Bio-based integrated pest management in rice: An agro-ecosystems friendly approach for agricultural sustainability

Climate change, environmental pollution and depletion of natural resources are among the prominent potential challenges for sustainable crop production and environment management in modern agriculture. Rice production systems have threatened with insect pests and weeds that significantly contribute to yield losses. Although control of insects, pests and weeds has remained the major effective plant protection tool, yet hazards to environmental safety urge the scientific community to propose alternative pest management strategies. Apprehensions about conventional agriculture sustainability have impelled the extensive introduction of integrated pest management (IPM). Bio-based IPM is one of the important component for controlling insect-pests, and weeds in rice, as it is environmentally benign, effective, and economically viable. In the present article, we analysed several studies to highlight the: (1) description of practices related to IPM in rice, (2) progress regarding the bio-based integrated insect pests and weed management with possible implications and scope, (3) allelopathy effectiveness for weed management in rice, and (4) present dilemmas and proposed future research directions. Briefly, this article explores the opportunities for the scientists and rice farmers to maximize the utilization of diverse natural control agents as a partial or total substitute for synthetic pesticides.

Evaluation and adoption of IPM modules in rice in Krishna district of Andhra Pradesh

India is the second largest producer and consumer of rice grown in the world after China. Pest and disease intensity is increasing slowly due to many factors. The control of leaf folder and stem borer, many methods has been adopted but insecticides are still playing a key role for its control. Integrated Pest Management (IPM) is one of the ecofriendly approach which can be utilized to control the non-judicial uses of insecticides to control rice insect pest. Krishi Vigyan Kendra, Ghantasala conducted frontline demonstrations to demonstrate the efficacy of rice IPM technology on farmers’ field under real farming situation during Kharif 2014 to 2016. Altogether totally 45 demonstrations were laid out over an area of 12 hectares. Increased yield ranged from 28.50 to 35.25 q/ha with average yield of 31.90 q/ha was observed in IPM module and also recorded highest grain yield of rice 35.25 q/ha in IPM module compared to non- IPM module. It has been observed that among IPM trained farmers, various cultural practices have wide spread adoption as against very low adoption of biological practices. Because of poor knowledge about pest-specific lures, its use and non - availability lead to poor adoption of the mechanical practices. The major problems reported in biological practices and its adoption were its slow action against the target pest, lack of easy availability, short shelf-life and low survival of these bio-agents on farmers’ field. Therefore, more awareness programmes and more demonstrations should be demonstrated on IPM module which is eco-friendly and safer to non-targeted organism in comparison to conventional insecticides.

INTEGRATED PEST MANAGEMENT (IPM) AND ITS APPLICATION IN RICE – A REVIEW

Rice is the staple food crop for more than half of the world’s population though it’s cultivation is done in only 11% of the world’s cultivable land. Several pests attack rice in different ways at different stages. Increased reliance on pesticides for pest control is found to be unsustainable and cost-ineffective. So, Integrated Pest Management (IPM) has been introduced as the best alternative for pest management in rice. IPM in rice helps to minimize risks to the environment and human health. Rice IPM uses the combination of cultural, use of resistant varieties, biological, physical, and chemical practices for pest control. Farmers Field School has been the most effective way to increase IPM knowledge among rice farmers. Such training helps to facilitate the farmers to apply ecologically informed farming practices. There are several challenges regarding the implementation of rice IPM. To increase IPM implementation in rice emphasis should be given on farmers’ training and education. The role of government is also vital for the successful implementation of IPM. This review article provides an overview of various IPM practices being performed in rice fields at present.

Survey of Integrated Pest Management (IPM) Practice in Vegetable Crops of Rupandehi District, Western Nepal

In the present study, documentation of farmer’s knowledge on Integrated Pest Management (IPM) was carried out in Rupandehi district during the year 2016. The objective of this paper is to assess the knowledge of farmers about IPM and its effectiveness in this district. It was carried out by conducting semi-structured interview with the participants of IPM FFS, vegetable growing farmers, stakeholders and local people with the help of standard questionnaire, Focus Group Discussion (FGD) and key informant interview. The IPM program is found to be conducted by an international non-government organization viz. Food and Agriculture Organization (FAO) and government organizations viz. Plant Protection Directorate (PPD), Agronomy Development Directorate (ADD) and District Agriculture Development Organization (DADO) through Farmer’s Field School (FFS) in this district. In total forty IPM FFS was conducted from 1998 to 2015 which provided training about IPM in rice and vegetable crops to 1057 farmers in which 393 were male and 664 female. Although a significant difference has been found in the knowledge about the amount of pesticide used, biological method of pest control for IPM by FFS participant and nonparticipant farmers, it is not observed in their behavior during the cultivation of crops in the farm. The result showed that only 5% of participants of Farmer’s Field School (FFS) are following IPM practices in their own farm after taking training. Int. J. Appl. Sci. Biotechnol. Vol 5(2): 237-242

PROTOCOL: Farmer Field Schools for Improving Farming Practices and Farmer Outcomes in Low‐ and Middle‐income Countries: A Systematic Review

Farmer field schools (FFS) are a common approach used to transfer specialist knowledge, promote skills and empower farmers around the world. At least 10 million farmers in 90 countries have attended such schools. FFS are implemented by facilitators using participatory "discovery-based" learning based on adult education principles. Many different implementing bodies have been involved. Field schools have a range of objectives, including tackling overuse of pesticides and other harmful practices, improving agricultural and environmental outcomes, and empowering disadvantaged farmers such as women. We conducted a systematic review of evidence on FFS implementation to investigate whether FFS make a difference, to which farmers, and why or why not. We synthesised quantitative evidence on intervention effects using statistical meta-analysis, and qualitative evidence on the barriers and enablers of effectiveness using a theory of change framework. The results of statistical meta-analysis provide evidence that FFS are beneficial in improving intermediate outcomes relating to knowledge learned and adoption of beneficial practices, as well as final outcomes relating to agricultural production and farmers' incomes. The findings suggest this to be the case for FFS promoting integrated pest management (IPM) technology, as well as other techniques. However, the rigorous impact evaluation evidence base is small and there are no studies that we were able to identify as having a low risk of bias. There is no evidence that neighbouring non-participant farmers benefit from diffusion of IPM knowledge from FFS participants. Therefore, they do not experience improvements in IPM adoption and agriculture outcomes. The evidence of positive effects on agricultural outcomes is largely limited to short-term evaluations of pilot programmes. In the few examples where FFS have been scaled up, the evidence does not suggest they have been effective in improving agricultural outcomes among participating farmers or neighbouring non-participants. Although empowerment is a major objective of many FFS, very few studies have collected information on this outcome in a rigorous manner. A few studies suggest farmers feel greater self-confidence. What explains the lack of scalable effects among FFS participants, or diffusion of IPM practices among the community? FFS differ from standard agricultural extension interventions, which tend to focus on disseminating knowledge of more simple practices such as application of fertiliser and pesticides, or adoption of improved seeds. The experiential nature of the training, and the need for the benefits of the FFS technology to be observed, are barriers to spontaneous diffusion. Furthermore, the effectiveness of scaled-up interventions has been hampered by problems in recruiting and training appropriate facilitators at scale. The review provides implications for policy, practice and research.

Evaluation of Lethal Effects of Chlorantraniliprole on Chilo suppressalis and Its Larval Parasitoid, Cotesia chilonis

Chlorantraniliprole was introduced into China from 2008 as a novel insecticide to control the rice stem borer, Chilo suppressalis (Walker). Cotesia chilonis (Matsumura) is the major parasitoid of C. suppressalis. We collected seven populations of C. suppressalis and two populations of C. chilonis in different locations in China in 2009 to investigate the lethal effects of chlorantraniliprole on them. The populations of C. suppressalis from different regions showed various LD 50 values ranging from 2.00 to 18.70 ng per larva. Chlorantraniliprole has negligible acute contact toxicity (LC 50>500 mg L −1) to C. chilonis and its oral toxicity is also much lower than that of fipronil (>2 800-fold difference in LC 50). The results indicated that chlorantraniliprole is a good alterative in rice integrated pest management (IPM) programs. The susceptibility data of C. suppressalis will be useful for monitoring resistance levels in future.

Investigation Of Information Sources And Communication Channels In Ipm Rice Farming In Fars Province, Iran

Extension of integrated pest management (IPM) as a component of sustainable agricultural development, involves empowering farmers. Facilitating the information accessibility of farmer groups seems as empowerment strategy. This strategy is based on identification ofrelated patterns, including information sources and communication channels of farmer groups. Along with this comment, a study was carried out through a survey research design for data collection to study the effects of information sources and communication channels inrice IPM. The statistical population of the study consisted all of rice growers in Marvdasht county, Fars province in Iran. Sample size included 90 farmers determined by Cochran's formula. Proportional random sampling technique was used to select farmers. A questionnaire was compiled to collect data. The results showed that out of studied information sources and communication channels, in order of importance, neighbors, agricultural inputs providers including pesticides dealers and to visit the farms that applied IPM obtained high priorities,. Also results showed that there were significant relationships among age, rice farming land area, farming experience, yield, participation in extension programs, accesslevel to pesticides, need feeling to pesticides, tendency level to decrease pesticide use , possibility of pests control naturally, and information sources and communications channels in IPM. Furthermore the results of multiple regression revealed that variables such as, rice cultivation land area, farmer participations in extension programs, and tendency level offarmers to decrease pesticide use and possibility of pests control naturally explained 70 percent of variance of applying rice IPM as dependence variable.

Insect pest management in tropical Asian irrigated rice.

Abundant natural enemies in tropical Asian irrigated rice usually prevent significant insect pest problems. Integrated pest management (IPM) extension education of depth and quality is required to discourage unnecessary insecticide use that upsets this natural balance, and to empower farmers as expert managers of a healthy paddy ecosystem. Farmers' skill and collaboration will be particularly important for sustainable exploitation of the potential of new, higher-yielding and pest-resistant rice. IPM "technology transfer" through training and visit (T&V) extension systems failed, although mass media campaigns encouraging farmer participatory research can reduce insecticide use. The "farmer first" approach of participatory nonformal education in farmer field schools, followed by community IPM activities emphasizing farmer-training-farmer and research by farmers, has had greater success in achieving IPM implementation. Extension challenges are a key topic for rice IPM research, and new pest management technology must promote, rather than endanger, ecological balance in rice paddies.

Integrated Pest Management in Rice

Integrated pest management (IPM) in rice has been mainly applied to irrigated, lowland paddy rice ecosystems which generally use more inputs and have higher yields ha−1 than rainfed ecosystems. Large scale implementation of IPM was stimulated in the 1970s in several Asian countries by pest resurgences resulting from indiscriminate insecticide use. Legislation has been enacted in at least five countries to support IPM and by 1992, approximately 0.05% of Asian farmers had received training in IPM. In at least two countries, adoption of IPM as national policy has resulted in large savings from reduced importation of pesticides with no reduction in total rice output or productivity. The inter-country programme on rice IPM of the Food and Agriculture Organization (FAO), the United Nations, the International Rice Research Institute and national programmes have all contributed to promoting rice IPM. Host plant resistance, deployed with location-specific cultural practices that conserve natural enemies, remains the basis for sustainable, low-cost rice IPM. Thresholds, monitoring and forecasting systems have little or no impact on farmer practice in the tropics; farmer group learning appears to be the most effective way towards IPM adoption.Manejo integrado de plagas en el arroz
