Evaluating grape growers' brand awareness and market share dynamics of pesticide and fungicide brands

Evaluation of Reduced Fungicide Applications for Disease Management in Cold-Climate Wine Grapes in Wisconsin.

Cold-climate wine grapes are produced on 8,000 ha in the North Central region of the United States. Wisconsin has experienced considerable growth, with a 26% increase in acreage since 2017. Chemical management of fungal diseases in cold-climate, interspecific hybrid grapes mirrors that of traditional Vitis vinifera cultivars despite significant differences in disease susceptibility. Most cold-climate cultivars display disease tolerance or resistance to key pathogens such as Plasmopara viticola (downy mildew), Erysiphe necator (powdery mildew), and Phyllosticta ampelicida (black rot). Current fungicide programs in Wisconsin's cold-climate grape industry underutilize genetic resistance, resulting in overreliance on at-risk fungicides and an increased threat of fungicide resistance development. In vineyard trials, the impacts of a reduced fungicide application number compared to current grower "Standard" programs was assessed for disease incidence and severity for five diseases: anthracnose, black rot, downy mildew, Phomopsis cane and leaf spot and powdery mildew. In 2022, with moderate disease pressure at both vineyard sites, there were no significant differences observed when fewer fungicides (six or five applications vs. four applications) were applied. In 2023, higher disease incidence was observed in the "Standard" spray program at one study location which received a greater number of fungicide applications. In both years, grape cultivar was a significant factor with the 'LaCrosse' displaying greater average disease severity than the 'St. Pepin' in both the "Standard" and "Reduced" Programs. These findings present a promising opportunity for cold-climate grape growers to reduce the number of fungicide applications while maintaining disease control and marketable yield.

Artificial Intelligence Techniques in Grapevine Research: A Comparative Study with an Extensive Review of Datasets, Diseases, and Techniques Evaluation.

In the last few years, the agricultural field has undergone a digital transformation, incorporating artificial intelligence systems to make good employment of the growing volume of data from various sources and derive value from it. Within artificial intelligence, Machine Learning is a powerful tool for confronting the numerous challenges of developing knowledge-based farming systems. This study aims to comprehensively review the current scientific literature from 2017 to 2023, emphasizing Machine Learning in agriculture, especially viticulture, to detect and predict grape infections. Most of these studies (88%) were conducted within the last five years. A variety of Machine Learning algorithms were used, with those belonging to the Neural Networks (especially Convolutional Neural Networks) standing out as having the best results most of the time. Out of the list of diseases, the ones most researched were Grapevine Yellow, Flavescence Dorée, Esca, Downy mildew, Leafroll, Pierce's, and Root Rot. Also, some other fields were studied, namely Water Management, plant deficiencies, and classification. Because of the difficulty of the topic, we collected all datasets that were available about grapevines, and we described each dataset with the type of data (e.g., statistical, images, type of images), along with the number of images where they were mentioned. This work provides a unique source of information for a general audience comprising AI researchers, agricultural scientists, wine grape growers, and policymakers. Among others, its outcomes could be effective in curbing diseases in viticulture, which in turn will drive sustainable gains and boost success. Additionally, it could help build resilience in related farming industries such as winemaking.

Wine grape grower perceptions and attitudes about soil health

Developing and adopting strategies that preserve soil health from degradation due to drastic changes in climate is critical for securing sustainable viticulture. For example, healthy soils promote water infiltration, nutrient cycling, and retention functions that support grape production. However, little research has evaluated drivers of growers' decision-making processes and actions towards soil management practices that impact soil health in vineyards. The objective of this study was to assess wine grape growers' perceptions and attitudes of soil health to identify grower's most important soil health functions and definition, and to understand how these might influence behavior related to soil management practices. Therefore, we conducted semi-structured interviews with 16 wine grape growers understand current barriers, motivations, and opportunities for adopting and/or maintaining practices for building soil health in vineyards. Most growers described healthy vineyard soils as balanced, biodiverse, self-sustaining, and resilient systems that provide nutrient, and water cycling functions and support high-quality wine grape production. Three categories of growers emerged based on soil health attitudes including Early Adopter (n = 3), Early Majority (n = 4) and Late Majority (n = 9) groups. The main barriers for adoption and maintenance of soil health practices were high costs, potential economic risks, and lack of information on how these practices influence grape production especially for the Late Majority group. Most growers were willing to adopt more soil heath practices if additional specific, practical information could be provided on outcomes of soil health practices for wine grape production systems—especially economic benefits. The outcomes of this study guide future soil health research and outreach activities to better support growers in building and protecting vineyard soil health while achieving viticultural goals.

Vine spacing of <i>Vitis vinifera</i> cv. Shiraz/101-14 Mgt. III. Grape and wine quality

Vine spacing effects of Shiraz/101-14 Mgt on a relatively high potential soil in the Breede River Valley, Robertson, South Africa, on grape composition and wine quality, were investigated. Canopies were VSP trellised and orientated approximately NNE-SSW. Spacing between rows was fixed at 2.2 m. In-row vine spacing changed from 0.3 – 4.5 m with increments of 30 cm (from 15151 – 1010 vines/ha). Grape composition and wine quality were monitored over six seasons and two grape ripeness levels. Decreasing trends of soluble solids (°B) and pH and increasing titratable acidity from narrow to wide spacing were observed. Sugar accumulation of wider spacings seemed delayed. Berry skin total anthocyanin index and phenol content showed virtually no change. Malvidin mono-glucoside and its p-coumaroyl and acetyl derivatives were present in the highest concentrations, followed by peonidin-, petunidin-, delphinidin- and cyanidin mono-glucosides and derivatives, each vine spacing treatment displaying a unique grape anthocyanin profile. The narrower spacing of vines seemed to favour skin anthocyanin accumulation compared to wider spacing. Decreasing trends in wine total anthocyanin intensity, anthocyanin density, and phenols were observed from narrow to wide spacing; all had higher levels in wines from riper grapes. Individual wine anthocyanin concentrations also showed qualitative profile changes. The first regression join points for all anthocyanins occurred around 1.8 – 2.4 m vine spacing; those for malvidin and derivatives consistently appeared at 1.8 m spacing. Although volatile compounds only seemed to respond to ripeness level and not to vine spacing, wine sensory quality generally decreased with wider vine spacing at both grape ripeness levels. Given the changes in biotic and abiotic growth conditions with wider vine spacing, the results likely displayed adaptation to the combined impact of increasing light exposure, berry temperature, physiological functioning, vegetative and reproductive growth ratios, and plant stress. The study showed the prominent role of plant spacing in sustainable grape growing and wine outcomes and thus the importance of judicious decision-making during the establishment and management of vines under any growth conditions and in any terroir.

Uses of Gibberellic Acid for Increasing Grape Production

Grapes are one of the most delicious fruit and have been farmed from thousands of years, growing from wild vine. Plant hormone is used for increase size and yield. This study goes into the significance influence of Gibberalic Acid (GA3) on grape farming, showing the ways in which this plant hormone has transformed the agricultural industry. Gibberellic acid is a hormone that is found naturally in plants and is essential for controlling several physiological functions. Many studies have been conducted on its use in grape cultivation. The main factor is growth and development of grape is vine. In grapes GA3 affects everything from flowering to fruit ripening. Enhancing yield is one of the main ways that GA3 helps with grapes production. GA3 encourage the growth of cluster by inducing cell elongation and division, which leads to increasing yield. In addition to satisfying consumers demand, the rise in grape yield helps for grape grower’s bottom line. Roles of application of GA3 on grape vine are different depends on their stages of flowering and fruit setting. It is also gave positive effect on rachis elongation which helps to get Healthy and export quality production. Overall, this review concluded that the Gibberellic Acid (GA3) is an important component linked with improving quality, size of berry, higher production.

Agrochemical Spray Technology Adoption and Safety Awareness Assessment in Crop Protection in Vineyard Cultivation

A study was conducted in the Jalna district of Maharashtra to assess the adoption pattern of spray technology, and safety awareness among grape growers. The respondents were selected through random sampling and data was collected through a structured interview. The study revealed that among marginal landholders (< 1 ha) back-pack type sprayer was mostly in operation with an adoption level of 75%. In small landholders (1-2 ha), horizontal triplex pump (HTP) sprayers with an adoption level of 51.85% followed by tractor-operated air-blast sprayers (40.75%) were prevalent pesticide spraying technologies. More than 2/3rd (76.00%) of medium landholders (2-4 ha) had adopted tractor-operated air blast sprayers. For the application of plant growth regulators, 62.5% of small farmers, 81.8% of medium, and 100% of farmers had adopted electrostatic sprayers. The number of chemical sprays per season varied from 25 to 100, making grapes one of the major pesticide-consuming crops. Capacity, efficiency, cost, and availability of sprayers on a custom hiring basis were the four major factors affecting the adoption of spraying technologies.

A Study of the Elemental Profiles of Wines from the North-Eastern Coast of the Black Sea

Due to the increasing consumer interest in wines with a controlled place of origin, PGI (Protected Geographical Indication) and PDO (Protected Designation of Origin), the most acute question is how to identify them. One of the most effective ways to confirm the place of origin of wine in global practice is a comprehensive study of the elemental profile using statistical analysis methods. In the period from 2020 to 2023, 152 grape samples of grapes were collected from various wineries in Crimea and Kuban. The grape must that was obtained from them was fermented in laboratory conditions. The elemental profile was determined in the prepared wines, which included 71 indicators. In the conducted work, it was revealed that wines from Crimea and Kuban differ statistically significantly in the concentration of the elements B, Ca, Cu, Mn, Na, Ni, Re, Si, Sn and U. At the same time, the contents of the elements U, Sn and Re prevail in wines from Crimea, and those of B, Ca, Cu, Mn, Na, Ni and Si prevail in wines from Kuban. At the same time, methods of univariate and multivariate statistics do not allow us to reliably classify wine samples from Crimea and Kuban by their place of origin. In order to reveal the non-linear dependence of the studied indicators in wines on the geographical place of grape growing, the method of a supervised learning Random Forest was used. After training the model on the dataset, the proportion of its correct predictions was 96%. The model used 61 parameters, among which the most important were Ni, Re, Ba, Rb, Na, U, Sb, Zn, Bi, Ag and Ti.

Influences of Cluster Thinning on Fatty Acids and Green Leaf Volatiles in the Production of Cabernet Sauvignon Grapes and Wines in the Northwest of China.

Cluster thinning has been widely applied in yield management and its effect on green leaf volatiles (GLVs) in wines has seldom been studied. GLVs are important flavor compositions for grapes and wines. This work aimed to investigate the impact of cluster thinning on these volatiles and their precursors in grapes and wines. Severe cluster thinning (CT1) and medium cluster thinning (CT2) were performed on Cabernet Sauvignon (Vitis vinifera L.) vines in two sites (G-farm and Y-farm) from Xinjiang province in the Northwest of China. The impact of cluster thinning treatments on the accumulation of GLVs and their precursors, long chain fatty acids (LCFAs) of grape berries and C6 volatiles, in resulting wines was investigated. Multivariate analysis showed that cluster thinning treatments induced significant changes in fruit and wine composition in both farms. In Y-farm, medium cluster thinning (CT2) significantly increased the average cluster weight of harvested berries. Additionally, both cluster thinning treatments (CT1 and CT2) increased fatty acids in harvested berries and CT2 led to an increase in C6 esters and a decrease in C6 alcohols in the wines of Y-farm under the warmer and drier 2012 vintage. However, the effect of cluster thinning was likely negative in G-farm due to its wetter soil and excessive organic matter. The treatments may be applicable for local grape growers to improve viticultural practices for the more balanced vegetative and reproductive growth of Cabernet Sauvignon grapevines. This work also provided further knowledge on the regulation of fatty acids and the derived C6 volatiles through the lipoxygenase (LOX) pathway.

Phenolic, Amino Acid, Mineral, and Vitamin Contents during Berry Development in ‘Italia’ and ‘Bronx Seedless’ Grape Cultivars

Understanding the variations in amino acids, phenolic compounds, elements, and vitamins between grape varieties is essential for optimizing grape production, fine-tuning dietary recommendations, and harnessing the health potential of grapes. In this regard, this comprehensive study investigated the compositional diversity of two distinct table grape cultivars, ‘Bronx Seedless’ and ‘Italia’, at various critical phenological stages (BBCH-77, -79, -81, -83, -85, and -89). The research findings demonstrated remarkable differences in the concentrations of key nutritional components. Bronx Seedless consistently exhibited higher levels of several amino acids, including glutamate, phenylalanine, and aspartate with concentrations reaching 49.6, 52.7, and 24.8 pmol μL−1, respectively, in contrast to Italia. Regarding phenolic compounds, Italia emerged as the richer source, with concentrations notably higher for compounds such as vanillic acid (18.2 µg g−1 FW) and gallic acid (37.4 µg g−1 FW). Mineral analysis revealed variable concentrations, with Italia grapes containing higher levels of Fe (91.0 mg/kg) compared to Bronx Seedless (87.1 mg/kg); however, Bronx Seedless had slightly elevated levels of K (31,089 mg/kg) compared to Italia (28,184 mg/kg). Concidering vitamins, Italia grapes showcased superior levels of Vitamin B1 (14.1 mg/100 g FW) and Vitamin A (11.0 mg/100 g FW), while Bronx Seedless had higher concentrations of Vitamin B6 (29.5 mg/kg), C (3.9 mg/100 g FW) and Vitamin B2 (36.9 mg/100 g FW). Principal component analysis (PCA) elucidated complex relationships within these components, offering insights into potential correlations and interactions. The heatmap visualization further indicated the concentration gradients across various samples, unveiling the intricate nutritional profiles of these grape cultivars. This research can aid grape growers and consumers in making informed decisions about grape cultivars and their corresponding health advantages.

Assessing the influence of climate controls on grapevine biophysical responses: a review of Ontario viticulture in a changing climate

Climate change presents unique challenges for grape growers across the world. In Ontario, three distinct viticultural regions are experiencing climatic shifts towards warmer growing seasons. According to historical records collected from Environment and Climate Change Canada, Lake Erie North Shore has transitioned from an intermediate-to-warm growing season classification, the Niagara Peninsula from the lower to upper limits of the intermediate zone, and Prince Edward County from cool to intermediate, when analyzing their average growing season temperatures. Terroir is directly related to vine water status, an indicator of grapevine stress. Biophysical responses controlled by air temperature and precipitation include fluctuations in vapour pressure deficits, evapotranspiration, and water-use-efficiency rates, as well as soil water content levels. By conducting an extensive literature review, the development of a conceptual model addresses how variations in climatic controls, under the scope of climate change, may influence grapevine water status, biophysical responses, and associated production outcomes for Ontario vineyards. Cool-to-intermediate air temperatures, when paired with increased precipitation will lead to no or low vine stress, increasing photosynthesis and transpiration rates, and variable plant water-use-efficiency levels, producing higher yields and lower quality grapes, if no management strategies are applied. Oppositely, higher air temperature as a product of climate change, when paired with variable precipitation may produce mild-to-severe stress, reducing yield, and increasing grape quality. With the appropriate management strategies, both traditional and new, growers may be able to accommodate for the influence of climate change on their vineyards.

Unveiling the transformations in phytochemicals and grape features: a thorough examination of 'Italia' and 'Bronx Seedless' cultivars throughout multiple berry development stages

Understanding the physical and phytochemical characteristics of grape cultivars across different berry development stages is crucial for optimizing grape production and quality in the agricultural and viticultural industries. The study, therefore, investigated the physical characteristics and phytochemical composition of 'Italia' and 'Bronx Seedless' grape cultivars harvested across six distinct periods. In grape cultivars displayed an intriguing journey in terms of resveratrol, ranging from 5.96 mg/kg in Period I to 11.59 mg/kg in Period VI. These vital compounds known for contributing to grape color and potential health benefits showed substantial variation across the grape cultivars and harvest periods. In addition, significant variations in phytochemical compositions were observed between 'Italia' and 'Bronx Seedless' grape cultivars, with 'Italia' generally exhibiting higher concentrations of key compounds such as resveratrol, pterostilbene, anthocyanidins, and flavonoids. The longitudinal analysis across six berry developmental periods highlighted a progressive increase in the concentrations of these phytochemicals in cultivar, indicating a dynamic evolution of grape biochemistry over time. Particularly, delphinidin-3-O-glycoside, cyanidin-3-O-glycoside, and petunidin-3-O-glycoside showed marked increases, indicating significant growth in anthocyanin content from Period I to Period VI. Utilizing PCA biplots and a hierarchical clustering heatmap, the study visually represented the relationships and variances among various phytochemical components. The insights revealed how certain compounds clustered together, suggesting similarities and dissimilarities. The positioning of compounds on these plots indicated their significance in characterizing grape cultivars and their maturation over time. In summary, the data underlined the strong influence of berry development time on phytochemical composition, emphasizing the importance of strategic grape harvesting to attain desired phytochemical profiles for wine or other grape products. The findings provide valuable insights for grape growers, winemakers, and researchers aiming to exploit the full potential of these compounds in grape-based products and for those interested in understanding the dynamics of grape phytochemistry.

Aerial spraying for downy mildew control in grapevines using a remotely piloted aircraft

Downy mildew is a major problem for grape growers, as this disease is difficult to control. Synthetic fungicides are used to treat downy mildew with handheld backpack and tractor sprayer applications, with high chemical exposure by operators. As important tools for maximising yield, application technologies must be studied to optimise control efficiency. The objective of this study was to evaluate the efficiency of fungicide spray application using Remotely Piloted Aircraft (RPA) for the control of downy mildew in grapevine, with different spray volumes. The study was divided into two experiments using 4 vine lines, 10 blocks and 5 treatments with different mixture volumes: Experiment 1 with RPA application of 5 mixture volumes - 0, 22, 44, 66, and 88 L ha−1; Experiment 2 with RPA application of 3 mixture volumes - 44, 66, and 88 L ha−1 and a backpack application of one mixture volume - 800 L ha−1. Coverage percentage, droplet density and volume median diameter (VMD) were evaluated. Downy mildew severity on grapevine leaves was assessed using visual analysis and a diagrammatic scale. The application of 44 L ha−1 provided the greatest coverage and droplet density in the upper and middle strata; however, the backpack application had a better droplet distribution than the RPA application. Treatments of 44 L ha−1 with RPA and backpack application (800 L ha−1) provided the best disease control. In the trellis system, RPA application must be improved because of the low coverage in the lower parts of the plant, and further studies with different spray nozzles and application heights are needed.

The use of ecologically safe means in the protection against sucking phytophages in the ampelocenoses of the Northern Black Sea region

Goal. To provide data on insecticides for protection of grapes from thrips and Japanese grape cicada and their influence on the number of entomophages, which is an important element for the organization of effective and environmentally friendly technology of grape growing.
 Methods. Combination of quantitative and qualitative methods in plant protection — entomology and biomethod. The use of generally accepted methods of analysis (hypothesis, experiment, induction and synthesis) provides sufficient information on the control of grape thrips and Japanese grape cicada under the conditions of using environmentally friendly means of protection, which is one of the main elements of modern technologies for optimizing agroecosystems and obtaining environmentally friendly products. The phytosanitary method of route surveys involves the identification of entomophages and the establishment of dominant species and prevalence of grape thrips and Japanese grape cicada among them. The field method ensures the study of the effectiveness of the elements of the integrated grape crop protection system. The laboratory method involved the identification of species diversity of beneficial fauna. The statistical method was used to calculate the data obtained, determine their accuracy and reliability.
 Results. The database was updated with environmentally safe products, and regulations for their use were established, which are focused not so much on pest control as on the overall optimization of the phytosanitary condition of plantations, obtaining environmentally friendly products and preserving beneficial fauna. Under natural conditions, without pesticide pressure, the number of predators in a multicomponent entomocomplex is many times higher than in traditional agrocenoses.
 Conclusions. The composition of preparations with a given direction of minimizing damage to beneficial fauna and, accordingly, the environment was formed. The results obtained and the conclusions formulated on their basis are of practical importance in terms of the prospects for the production of environmentally friendly products by applying environmentally friendly and effective methods of controlling the number of sucking pests and preserving the natural agrobiocenosis.

The Impact of Marketing Channels on Farmers' Income: An Empirical Study of Kabul, Parwan and Kapisa Grape Farmers

Among the 150 grape growers in the three provinces of Kabul, Parwan and Kapisa in Afghanistan, the possibility of contract signing between farmers in Kabul and traders is lower, and that between farmers in Parwan and Kapisa and farmers' organizations is higher. 26.67% of farmers signed contracts with farmers' organizations, 45.33% of farmers signed contracts with traders, and 28.00% of farmers directly carried out market transactions without signing sales contracts. The average age of grape farmers is 30.9 years old, and the average planting period is 10.4 years. The results show that farm distance and Internet use have a significant negative impact on the non-adoption of contract sales, while Internet use and farm distance have a significant positive impact on the adoption of sales contracts with traders; farmers' planting years have a positive impact on the signing of sales contracts with traders; the increase of sales price reduces the feasibility of signing contracts with traders Compared with the farmers who get loans from friends, family members and banks, the farmers who get loans from farmers' organizations are less likely to sign contracts with farmers' organizations.Compared with the contracts signed by farmers' organizations, the signing of marketing contracts with traders has a positive impact on Farmers' welfare. The selective amendments of all marketing contracts are significant, indicating that there is a selective bias in the unobserved factors.

Determination, temporal variation and potential health risk assessment of pesticide residues in grapes from South and Southwest China

Pesticide residues in grapes from South and Southwest China were determined using the QuEChERS procedure and UHPLC-MS/MS and GC-MS/MS methods. The 4-year monitoring and survey showed 94.6% of the 1341 samples of grapes collected from eight main production areas contained one or multiple pesticide residues (above the respective LOQs). Overall, 40 pesticides were detected, including 24 fungicides, 12 insecticides, 2 acaricides and 2 plant growth modulators, of which one pesticide was unauthorised for use in treating grapes. Two or more pesticide residues were discovered in 87.4% of the samples (above the respective LOQs), and pesticide residues in 5.7% of the samples exceeded the MRLs, such as difenoconazole, cyhalothrin, propiconazole, etc. The main risk factors affecting the safety of grape before 2019 were difenoconazole, cyhalothrin and cyazofamid. After 2019, however, the frequency of occurrence of the above pesticides significantly declined, and the banned or restricted pesticides including omethoate were not found, which was credited to the stricter supervision and management policies by local governments. Despite the high detection rates and multi-residue occurrence of pesticides in grapes, about 84% of the samples were compliant with regulatory standards. Moreover, the accumulative chronic diet risk determined from ADI is very low. This study and timely monitoring can ensure that grape growers comply with GAP and minimise the occurrence of residues.

Zeolite application and irrigation during ripening reduced berry sunburn damage and yield loss in cv. Sangiovese (Vitis vinifera L.).

Climate change poses significant challenges to the grapevine cultivation for wine production. In the last years, the occurrence of extreme weather events such as intense heat waves and prolonged period of drought increased sunburn damage with negative consequences to yield and berry composition. Short-term adaptation strategies are urgently needed to mitigate these effects. In this light, our study aimed to evaluate the efficacy of zeolite application on the canopy and irrigation during ripening on sunburn damage, yield, and berry composition in cv. Sangiovese (Vitis vinifera L.). Over 3 years (2021-2023), canopy management and irrigation treatments were arranged in a strip-plot design. Canopy management treatments included leaf removal on the cluster zone, with and without zeolite application, and no defoliated control; irrigation treatments comprised irrigation from berry softening and no irrigation. Both zeolite application and irrigation reduced sunburn damage, thus mitigating yield loss. Regarding berry composition, zeolite application did not alter the main parameters whereas irrigation led to reductions in sugar and anthocyanin concentrations. These findings suggest that zeolite application and irrigation during ripening represent promising and cost-effective solutions for grape growers facing climate change-induced challenges. However, further studies are necessary to optimize timing of irrigation to avoid detrimental effects on anthocyanin accumulation.
