Effectiveness and Adoption of IRAC Group 30 Insecticide Molecules in Chilli Cultivation

The introduction of IRAC Group 30 insecticides, which act as GABA-gated chloride channel allosteric modulators, represents a significant advancement in pest management due to their novel mode of action and prolonged residual activity. These insecticides, including meta-diamides and isooxazolines, have gained importance in controlling insect and mite pests in high-value crops such as chilli. However, their increased use may impose selection pressure on pest populations, making it essential to understand both their effectiveness and adoption patterns at the farm level. In this context, the present study was undertaken to analyse the effectiveness of Group 30 pesticide molecules on chilli crop and to identify the factors influencing their adoption by chilli farmers in Guntur district of Andhra Pradesh. The study was conducted in two major chilli-growing mandals, Prathipadu and Medikonduru, where four villages were selected based on maximum chilli acreage. A total sample of 120 chilli farmers was selected through random sampling. Primary data were collected through personal interviews using a structured interview schedule. The study examined farmer's opinions, perceived effectiveness of Group 30 pesticides in terms of pest control, yield improvement, cost, application rate, potency and risk factors, as well as economic, social and technical factors influencing adoption. Analytical tools such as Likert's five-point scale and Garrett's ranking technique were employed to quantify perceptions and prioritize influencing factors. The results revealed that all sampled farmers were aware of and had adopted Group 30 pesticide molecules. Most farmers perceived these insecticides as effective in controlling pests and improving crop yield and overall crop health. Input dealers played a crucial role as information sources influencing pesticide choice and usage. Despite generally positive perceptions, concerns related to cost, safety, environmental impact and market competition were also reported. The study concludes that while Group 30 insecticides are widely accepted and beneficial for chilli cultivation, continuous farmer training, technical guidance and supportive extension services are essential to ensure their safe, effective and sustainable use.
