Agriculture innovation: the important effects of certification and technology innovation

PurposeThis study aims to find how trade development and digitalization affect smart-green production. Four factors are investigated in these effects (certification, technology innovation, natural resource management, low pesticides).Design/methodology/approachThe mix-method approach was employed from validating the measurement scale to test the proposed hypotheses. At first, the grounded theory is the most authoritative and standard research method in qualitative research. Secondly, quantitative analysis was employed to draw conclusions about the impact of digitalization and trade development on smart-green agricultural production.FindingsThe results found that digitalization and trade development impact the development of smart-green agricultural production through certification employment, technology innovation, and a decrease in pesticide usage. Moreover, digitalization and trade development also indirectly affect the development of intelligent green agricultural production. Meanwhile, digitalization has a higher impact than trade development.Research limitations/implicationsThis research is based on the premise that digitalization and trade development can drive smart green agricultural production. Still, some studies have found a deviation between trade development and environmental protection. Hence, future research can explore the incentive effect of trade development and digitalization on other industries. Second, the measurement of the dependent variables in this study is based on the premise that smart-green agricultural production has not been widely promoted, so the changes in production before and after the whole public participation in smart-green output have yet to be reflected.Originality/valueSmart green production in agriculture is essential for a transition economy and the world to meet food security and protect the environment. However, the effects of certification, technology innovation, natural resource management, and low pesticides on smart-green agriculture production have yet to be identified. Insights from this study can help governments, policy-makers, and farmers in emerging economies by adapting their strategies within their local contexts.

Assessment of pesticide knowledge, Safety Practices and postharvest handling among cocoa farmers in South Western Nigeria

Cocoa beans are susceptible to fungal contamination during processing and storage. The knowledge of the use of pesticides and post-harvest handling of cocoa beans among farmers is of great importance for safe consumption. The study evaluated common cocoa production and post-harvest practices of farmers in selected study locations in South Western Nigeria. Primary data were collected through the administration of structured questionnaires, and interviews. The collected data were analyzed using inferential descriptive statistics. The results of 394 farmers showed that 52.9 % in Osun and 47.3 % in Oyo were primarily farmers by occupation, the rest had other ventures. The majority of cocoa farmers were men:83.6 % in Oyo State, 88.2 % in Osun state and 87.9 % in Ondo state. 28.6 % and 32.7 % of farmers were aged 51–60 in the Ondo and Oyo communities, respectively. Osun farming communities are dominated by young adults (51 %) of 31–50 years, followed by Ondo 40 % and36 % of farmers in Oyo State. Most cocoa farmers were married with 4–6 children as the most common household size in Osun (51 %), Ondo (60.4 %) and 49.1 % in Oyo State. The literacy level of farmers in cocoa communities was the highest in Oyo state where 47.3 % had tertiary education. Farmers in Oyo State had better knowledge of the dangers of pesticides than Ondo and Osun. However, ignorance of dangers in agrochemicals was higher among Osun farmers than in Ondo State. The highest (18 %) pesticide use during storage was recorded among Oyo farmers, while the least (11.0 %) was recorded among farmers in Ondo State. Pesticide usage was more abundant in Osun (50 %) during cocoa production than in the other study areas. The majority of farmers were positively disposed to make use of nose masks during agrochemical application, meanwhile, 69 %, 62 %, and 61 % of farmers used them already in Oyo, Ondo, and Osun states, respectively. Educational qualification (χ2 = 9.176, p = 0.027) of cocoa farmers was significantly related to knowledge of best practices. Farmers with higher education have a greater ability to receive and process information relating to global best practices in production, postharvest, and pesticide handling in cocoa. In conclusion, cocoa farmers’ knowledge of processing, use of pesticides, and storage practices differed from one location to another. Intensive orientation and more enlightenment by extension workers against indiscriminate use of pesticides in cocoa plantations and stores must be consistently and continuously done.

Assessing the Gray Water Footprint Impact of Pesticide Use in Tommy Atkins Mango Cultivation: A case study in the Semi-Arid Region of São Francisco Valley, Brazil

Mango production, particularly of the Tommy Atkins variety, is prominent in the São Francisco Valley region of Northeast Brazil due to favorable conditions and year-round cultivation facilitated by irrigation and growth regulators. However, concerns arise over its significant water footprint and heavy pesticide usage, prompting a study on the gray water footprint of pesticides applied to Tommy Atkins mangoes in Sub-middle São Francisco Valley-Pernambuco, Brazil. Utilizing models by Hoekstra et al. (2011) and Paraiba et al. (2014), the study estimated the Gray Water Volume (GWV) and assessed potential water contamination using the GUS Index and GOSS method. Results suggest minimal groundwater pollution risk but moderate surface water contamination risk. The GWV ranged from 106 to 107 m3 ha-1, with the model of Paraiba et al. (2014) showing higher environmental sustainability due to considering toxicity to aquatic non-target organisms. Despite this, both models indicate a high gray water footprint. The pesticide ranking derived from these findings can aid in selecting environmentally safer pesticide mixtures for mango cultivation, aiming to balance water protection and agricultural productivity.

Effects of exogenous chloride ions on the migration and transformation of Cd in a soil-rice system

Soil cadmium (Cd) contamination has emerged as a significant global environmental concern, posing numerous risks to individual organisms and entire ecosystems. Concurrently, the global increase in pesticide usage has elevated the influx of chloride ions (Cl−) into the soil. Given Cl−’s robust ability to coordinate and complex with various heavy metal ions, understanding its influence on the migration and transformation of Cd in soil-rice systems is essential for the rational application of pesticides and the effective mitigation of soil heavy metal pollution. In this paper, we explained the effect of Cl− on the environmental behavior of Cd in the soil-rice system in terms of growth traits, Cd uptake and accumulation by rice, and Cd solid-solution phase interface behavior through pot experiments and sand culture experiments. The results showed that Cd concentrations in all parts of the rice treated with CaCl2 during the filling period were lower than those in the Ca(NO3)2-treated group, with Cd accumulation diminishing as Cl− concentration increased. This suggests that the filling period is critical for Cd uptake and accumulation in rice. Unlike the accompanying anion NO3−, exogenous Cl− reduced Cd concentrations in the soil solution but increased them in rice. Notably, when the Cd/Cl ratio ranged from 0.625 to 2.5, Cl− formed predominantly CdCl+-complexes with free Cd2+ in the soil solution, enhancing the mobilization of Cd bound to soil particles and its subsequent absorption by rice. This study aims to assess Cl−’s effect on Cd migration and transformation in soil-rice systems, providing insights for safe rice production on Cd-contaminated soils and rational use of chlorine-containing pesticides.

Development and evaluation of a rope climbing sprayer robot for greenhouse environment

The ever-increasing population has promoted inventions and innovations such as greenhouse cultivation to enhance agricultural production in terms of both quantity and quality. Despite its advantages, greenhouse cultivation provides favorable conditions for the spread of diseases and pests. While agricultural pesticides have been exploited to protect plants and crops and to combat their diseases, they are unfortunately a major source of environmental pollution. In this study, a smart sprayer rope climbing robot was designed to spray the plant row from the side in two directions (top to bottom and vice versa). Using the Mylar sheets to collect and measure droplets, the robot's performance was evaluated in terms of the effects of nozzle speed (12, 15, and 18 m/min), pressure (1.4, 2.6, and 3.6 bar), and type (flat-fan and hollow-cone nozzles) as well as leaf position (upper, middle, and lower) on such indices as numerical median diameter (NMD), volumetric median diameter (VMD), coverage percentage, uniformity index of droplet spectrum, and droplet number per unit area. In addition, comparisons were made between the proposed sprayer robot and the two back-pack and trolley sprayers in terms of their pesticide consumption and user exposure levels. Maximum and minimum pesticide consumption rates of the robot were recorded at 1.16 L and 2.6 L, respectively, when it was used to spray two rows 15 m long in a greenhouse. Finally, pesticide consumption rate by the robot was found to be by 55% and 82.9% less than those recorded for the backpack and trolley sprayers, respectively.

Pesticide reduction: clustering organic croplands

Organic and conventional farms often coexist, yet their proximity does not ensure compatibility. Larsen et al. reveal that being surrounded by organic fields reduces pesticide usage in organic fields but increases it in conventional fields. We discuss these findings, emphasizing the need to cluster organic croplands for reduced pesticide use.

Assessing the effect of COVID 19 lockdowns on the composition of organic compounds and potential source of PM2.5 in Hanoi, Vietnam.

The ambient air quality during COVID-19 lockdowns has been improved in many cities in the world. This study is to assess the changes in persistent organic pollutants in PM2.5 during the COVID-19 lockdown in Hanoi. Individual organic species in PM2.5 ((e.g., polycyclic aromatic hydrocarbons (PAHs), polychlorobiphenyls (PCBs), and organochlorine pesticides (OCPs)) were measured in an urban residential area in Hanoi from before the March 10th to April 22nd, 2020, including before the partial lockdown (BL) and the partial lockdown (PL) phases. During the PL phase, the concentration of Σ14PAHs and Σ28PCBs was reduced by 38 and 52% compared with the BL period, respectively. The diagnostic ratio method implied that the sources of PAHs within the PL phase had a less effect on traffic and industrial activities than in the BL phase. The characteristic ratio method indicated that PCBs were mixed by commercial product and combustion process in both the BL and the PL periods, however, the source of PCBs in the BL phase was influenced by municipal waste incineration more than those in the PL phase. The decreasing concentration of Σ20OCPs during the partial lockdown was attributed to the restriction of human activities during the quarantine period. The results suggested that the source of OCPs was probably derived from the usage of pesticides in current and, historical degradation or the transportation of pesticides from the soil to the atmosphere.

Stop blaming the farmer: Dispelling the myths of ‘misuse’ and ‘safe’ use of pesticides to protect health and human rights

The negative effects of pesticide use in low- and middle-income countries (LMICs) are often blamed on the “misuse” of pesticides. The industry and government narrative is that the use of highly hazardous pesticides is safe when instructions are followed, and that harm occurs due to “irrational” and “improper” human behavior, linked to lack of knowledge by farmers. This assumption does not consider the real-life situations of pesticide users in LMICs, including structural, economic, and social barriers that make it impossible to follow “safety practices.” This “blame the farmer” narrative leads to ineffective risk mitigation measures, perpetuating and increasing people’s exposure to pesticide harms and endangering their lives. It is governments that allow the use of highly hazardous pesticides in their jurisdictions, and pesticide companies that produce them—not individual pesticide users in LMICs—who should bear the main responsibility for the prevention of the negative impact of these products. A human rights-based approach to pesticide management and the interpretation of international guidance that avoids the blaming narrative but puts real people, their health, and human rights first is needed to reduce and eliminate toxic exposure and save lives and health.

Occurrence, seasonal variations, and spatial distributions of current-use organoamine pesticides in the atmosphere of Shanghai, China

An increasing trend in pesticide usage requires a better understanding of the occurrence, fate, and exposure risk of current-use organoamine pesticides (CUOAPs) in the atmosphere as the population grows and climate changes. 33 target CUOAPs were measured in 89 atmospheric samples collected in different seasons from Shanghai, including gaseous and particulate phases. The total concentrations of gaseous phase CUOAPs ranged from 407 to 2980 pg/m3, with an average value of 887 ± 426 pg/m3. Conversely, the total concentrations of particulate CUOAPs were found to be one to two orders of magnitude lower than those in the gas phase, with low detection frequencies. Diphenylamine and Molinate were ubiquitous and predominant in the gaseous CUOAPs. The average total concentrations of gaseous CUOAPs were significantly higher in spring than those in winter and autumn seasons. Gaseous CUOAPs concentrations increased from rural to downtown areas during spring, showing different spatial distribution from winter and autumn. A significant correlation was observed between temperature and the presence of Dicloran, Pirimicarb, Diphenylamine, and Acetochlor. Agricultural activities and city pest control may be the main sources of CUOAPs, while meteorological factors including temperature and wind speed also impact the dispersal of these chemicals in the atmosphere. The increased risk of exposure was observed to be higher during the spring season compared to the autumn and winter seasons, aligning with the pattern of heightened utilization of CUOAPs during the planting and growing phases. The daily inhalation exposure of CUOAPs did not exceed the current oral reference dose.

Trends of Suicidal Poisoning in Southern part of Assam

Suicide is a leading cause of mortality among young people in many countries, making it a serious global public health problem. It is estimated that around 20% of global suicides are due to pesticide poisoning. This study was conducted with an objective to find out the commonest suicidal poison and its demographic distribution. This study was designed on victims of suicidal poisoning brought for medicolegal autopsy at Silchar Medical College and Hospital, Silchar, Assam between 15th October 2017 and 14th October 2022. Required information for the study was gathered from inquest reports, autopsy reports, chemical examiner’s analysis report of viscera and available documents in the departmental records. The collected information was statistically analysed using Microsoft excel version 2019. Out of 64 cases, poison was detected in 33 Cases. Male victims surpassed females with highest number of victims from age group 21-30 years. Most common poisoning agent was organophosphorus compounds. Educational and awareness programs regarding usage and storage of pesticides can become an important step for the prevention of deaths due to poisoning. However more research is needed to better understand suicides involving pesticides in their cultural contexts

Environmental pesticide exposure and Alzheimer's disease in southern Spain: A cross-sectional study

The intensive cultivation under plastic in southern Spain has made the agricultural model highly productive. Although strict regulations on pesticide usage exist, exposure to pesticides in the environment has been associated with an increased appearance of neurodegenerative diseases including Alzheimer's disease (AD). A cross-sectional study was performed to examine the prevalence and risk of AD related to pesticide exposure in Andalusia (Spain). We utilized the Odds Ratio statistical test to compare the prevalence rate of AD in the exposed and unexposed areas. 40,044 cases were collected from computerized hospital records between 2000 and 2021. Districts with higher pesticide use showed significantly higher prevalence rates and increased risk of developing AD, compared to those with lower pesticide use. These findings provide further evidence supporting an increased risk of AD following environmental exposure to pesticides at the level of the general population.

Metal-organic framework as nanocarriers for agricultural applications: a review

Agrochemicals are substances used to promote plant growth and eradicate pests; and are essential to meeting the world food demand both qualitatively and quantitatively. Unfortunately, their extensive usage has resulted in certain significant problems, i.e., soil contamination, bioaccumulation, and the development of pest resistance. Consequently, there is a need for a reduced and more regulated usage of agrochemicals. The development of sustainable nanomaterials is encouraged in agricultural nanotechnology to minimize the usage of conventional fertilizers, herbicides, and pesticides. Metal-organic Framework (MOF)s are porous materials made of functional organic ligands and metal nodes or clusters connected by covalent bonds. Researchers are becoming increasingly interested in using MOF in a variety of sectors. The features of engineered MOFs have the potential to be an optimal strategy for producing impressively unique results in agricultural research. They also have advantages in terms of biocompatibility and biodegradability, which can be leveraged to boost the efficiency of traditional agrochemicals administration. Controlled release of agrochemicals offers an innovative solution to decrease the nutrient uptake rates and contamination of the environment. The application of MOF nanoparticles as nanocarriers to modify the loading and release properties of agrochemicals is particularly highlighted in this review.

Effects of abamectin nanocapsules on bees through host physiology, immune function, and gut microbiome

Pesticide usage is a common practice to increase crop yields. Nevertheless, the existence of pesticide residues in the surrounding environment presents a significant hazard to pollinators, specifically the potential undisclosed dangers related to emerging nanopesticides. This study examines the impact of abamectin nanocapsules (AbaNCs), created through electrostatic self-assembly, as an insecticide on honey bees. It was determined that AbaNCs upregulated detoxification genes, including CYP450, as well as antioxidant and immune genes in honey bees. Furthermore, AbaNCs affected the activity of crucial enzymes such as superoxide dismutase (SOD). Although no apparent damage was observed in bee gut tissue, AbaNCs significantly decreased digestive enzyme activity. Microbiome sequencing revealed that AbaNCs disrupted gut microbiome, resulting in a reduction of beneficial bacteria such as Bifidobacterium and Lactobacillus. Additionally, these changes in the gut microbiome were associated with decreased activity of digestive enzymes, including lipase. This study enhances our understanding of the impact of nanopesticides on pollinating insects. Through the revelation of the consequences arising from the utilization of abamectin nanocapsules, we have identified potential stress factors faced by these pollinators, enabling the implementation of improved protective measures.

Analysis of nationwide soil pesticide pollution: Insights from China

China is a typical agricultural country that heavily relies on pesticides. Some pesticides can remain in the soil after application and thus pose a significant threat to human health. In order to characterize the status and hazards of nationwide soil contamination, this study extracted concentration data from published literature and analyzed them by a scoring approach, standard comparison and health risk assessment. For the soil pollution score, northern regions got the highest values, such as Henan (0.63), Liaoning (0.55), Heilongjiang (0.54) and Jilin (0.53), which implies high soil pesticide residues in these provinces. In contrast, Qinghai (−0.77), Guizhou (−0.64) and Tibet (−0.63) had lower scores. China's soil pesticide standards cover only 16 pesticides, and these pesticide concentrations were all below the corresponding standards. Direct exposure to soil pesticides in this study generally posed a negligible risk to children. Furthermore, pesticide dissipation and usage intensity in each province were analyzed as they were possible influences on pollution. The result showed that soil in the northern regions could accumulate more pesticides than those in the southern regions, and this geographic pattern was basically consistent with the distribution of soil pollution. However, the relationship between agricultural activities and soil pollution was less well characterized. It is recommended to establish a long-term monitoring database for pesticides and include more pesticides in regulatory frameworks. Additionally, efforts to accelerate pesticide degradation and shift the planting structure to reduce pesticide usage can help alleviate the pressure on soil from pesticides. This study can serve as a critical reference for policymakers and stakeholders in the field of agriculture.

Development of Regenerative Tea Cultivation Models through Dual Approach of Soil and Plant Health Management towards Crop Sustainability, Soil Quality Development, Pesticide Reduction and Climate Change Mitigation: A Case Study from Lakhipara Tea Estate,

Climate change is a reality and its impact on the tea plantations is apparent in the rise of pest intensity, higher agrochemical use, inconsistent crop yields, declining grand growth period, increased abiotic stress and various other challenges; that threaten long-term sustainability of the Indian tea sector. The urgency to adopt sustainable practices is increasing by the day but to gain time bound results a comprehensive focus encompassing soil and plant health development will be crucial. To deal with climate challenge head-on, the Indian tea industry is making changes at various levels of operations. The sustainable tea initiative at Lakhipara tea estate, was one such attempt by the Goodricke Group Limited in their Dooars tea growing region of West Bengal. The program was initiated in 2014 with an aim to reduce pesticide use, improve soil quality, and produce quality teas while sustaining crop yields, improving renewable energy use and lowering the carbon footprint. Adoption of Inhana Rational Farming (IRF) Technology and taking the essence from ‘Trophobiosis Theory’ of French Scientist F. Chaboussou, the program focused on management of soil and plant health. Three years evaluation of crop yields in respect of the budgeted crop, revealed on an average an excess of 78 kg/ha/year in the project area. In rest of the garden area a contrasting crop loss of 118 kg was recorded per ha during the same period. The higher crop performance positively correlated with the higher nutrient use efficiency which was 17.7 percent higher in the project area (NUENPK : 8.86) as compared to the general garden area (NUENPK : 7.53), which reflected the impact of plant health management towards enhanced nutrient uptake, assimilation and utilization. Assessment of pesticide usage, revealed up to 77% decrease in usage in the project area during 2014-16, as compared to the pre- project year. Comparison with pesticide usage of the Dooars tea growing region during this same period, indicated a 62% lower Crop Pesticide Pollution Index (CPPI) in the project area. The finding indicated a 52 to 77% reduction in the accumulated toxicity potential of the applied pesticides in the project area; thereby accrediting safer tea development under this program, when adjudged in terms of pesticide residue. Assessment of soil quality revealed an overall eight percent increment in Soil Fertility Index (FI) value, with significant improvement in soil microbial activity potential (MAP) values i.e., by almost four times. The finding pointed towards the favourable impact of soil health management primarily through Novcom composting towards enhancement of soil microbial interactions. Post three years of experimentation the overall Soil Quality Iindex (SQI) value increased by 6% in the project area. The finding corroborated a concurrent 6.72% increase in the soil organic carbon stock during the same period. Reduction in use of non- renewable inputs viz. chemical fertilizers and pesticides in the project area was indicated by approximately 40 percent enhancement in energy use efficiency and energy productivity post the assessment period. Carbon assessment in terms of kg CO2 equivalents/ kg made tea (using ACFA version 1.0) indicated approx. 65 to 70 % lower footprint in the project area, primarily due to 20 to 30 % reduction in chemical fertilizers and 60 to 70 % reduction in the use of synthetic pesticides. The results indicated that while integrated soil management is the pre-requisite criteria towards rejuvenation of soil health and for restoration of the habitat for predators, it does not play a direct role in reducing the pest pressure and simultaneously the requirement of pesticides. Physiologically activated plants/ bushes on the other hand; due to their higher nutrient assimilation capacity and efficient protein synthesis are always lesser susceptible to pest attack. Hence, focus on activation of plant physiology can reduce the plant- pest interaction leading to a natural reduction in the requirement for pesticides vis-à-vis the pesticide usage.

Influencing factors and risk assessment of phthalate ester pollution in the agricultural soil on a tropical island

Phthalate esters (PAEs) are widely prevalent in agricultural soil and pose potential risks to crop growth and food safety. However, the current understanding of factors influencing the behavior and fate of PAEs is limited. This study conducted a large-scale investigation (106 sites in 18 counties with 44 crop types) of 16 types of PAEs on a tropical island. Special attention was given to the impacts of land use type, soil environmental conditions, agricultural activity intensity, and urbanization level. The health risks to adults and children from soil PAEs via multiple routes of exposure were also evaluated. The results showed that the mean concentration of PAEs was 451.87 ± 284.08 μg kg−1 in the agricultural soil. Elevated agricultural and urbanization activities contributed to more pronounced contamination by PAEs in the northern and southern regions. Land use type strongly affected the concentration and composition of PAEs in agricultural soils, and the soil PAE concentration decreased in the order of vegetable fields, orchards, paddy fields, and woodlands. In paddy fields, di-isobutyl phthalate and di-n-butyl phthalate made more substantial contributions to the process through which the overlying water inhibited volatilization. Soil microplastic abundance, pesticide usage, crop yield, gross domestic product, and distance to the nearest city were calculated to be the major factors influencing the concentration and distribution of PAEs. Soil pH, organic matter content, microplastic abundance and the fertilizer application rate can affect the adsorption of PAEs by changing the soil environment. A greater risk was detected in the northern region and paddy fields due to the higher soil PAE concentrations and the dietary structure of the population. This study reveals important pathways influencing the sources and fate of PAE pollution in agricultural soils, providing fundamental data for controlling PAE contamination.

Climate change and crop production nexus: assessing the role of technological development for sustainable agriculture in Vietnam

PurposeThis study aims to examine the effects of climate change and agricultural technologies on crop production in Vietnam for the period 1990–2018.Design/methodology/approachSeveral econometric techniques – such as the augmented Dickey–Fuller, Phillips–Perron, the autoregressive distributed lag (ARDL) bounds test, variance decomposition method (VDM) and impulse response function (IRF) are used for the empirical analysis.FindingsThe results of the ARDL bounds test confirm the significant dynamic relationship among the variables under consideration, with a significance level of 1%. The primary findings indicate that the average annual temperature exerts a negative influence on crop yield, both in the short term and in the long term. The utilization of fertilizer has been found to augment crop productivity, whereas the application of pesticides has demonstrated the potential to raise crop production in the short term. Moreover, both the expansion of cultivated land and the utilization of energy resources have played significant roles in enhancing agricultural output across both in the short term and in the long term. Furthermore, the robustness outcomes also validate the statistical importance of the factors examined in the context of Vietnam.Research limitations/implicationsThis study provides persuasive evidence for policymakers to emphasize advancements in intensive agriculture as a means to mitigate the impacts of climate change. In the research, the authors use average annual temperature as a surrogate measure for climate change, while using fertilizer and pesticide usage as surrogate indicators for agricultural technologies. Future research can concentrate on the impact of ICT, climate change (specifically pertaining to maximum temperature, minimum temperature and precipitation), and agricultural technological improvements that have an impact on cereal production.Originality/valueTo the best of the authors’ knowledge, this study is the first to examine how climate change and technology effect crop output in Vietnam from 1990 to 2018. Various econometrics tools, such as ARDL modeling, VDM and IRF, are used for estimation.

Apivectoring: Harnessing pollinators for sustainable crop protection and pollination

Apivectoring, or Pollinator Biocontrol Vector Technology, employs bees to distribute biological control agents, offering a sustainable solution for managing plant diseases and insect pests while enhancing crop yield and quality. The most commonly used vectors in apivectoring are honey bees and bumble bees, though there’s potential to explore other pollinator species. Commercial dispensers like BeeTreat Dispenser®, BVT Inoculum Dispenser® and Flying Doctors® have been developed in countries like Finland, Belgium, and Canada, respectively. Though initially pioneered in North America, Australia, and Europe, this method is now being evaluated in India. The technology is a promising alternative to chemical pest control, reducing pesticide usage and ensuring crop pollination, although challenges remain in regions deprived of local rearing and/or research facilities.
