“…It is a non systemic, broad-spectrum insecticide and acaricide with contact and stomach action and being extensively used for the control of lepidopteran group larvae, whitefly and mites on cotton, pigeonpea, chilli and vegetable crops (Sharma et al, 2018;Yadav et al, 2015). Further, profenofos efficacy on pod borer and pod fly infesting pigeonpea was in the range of 25 to 85% when used as ovicide and larvicide (Srivastava and Mohapatra, 2003;Chandrayudu et al, 2006;Malathi, 2007).…”

Background: Pigeonpea is a drought resistant legume crop, cultivated in semiarid tropical and subtropical regions of the world mainly for its protein enriched seeds. Insect pests are major biotic constraints implicating yield losses of staggering dimensions. Profenofos is being used for management of pigeonpea pod borer and studying the pattern of dissipation, residual occurrence and hazard index for consumption of pigeonpea grain contaminated with profenofos is very important. Methods: A simple, sensitive and reproducible method for analysis of profenofos in pigeonpea green pods and dry grain was standardized and validated using liquid chromatography tandem mass spectrometry (LC-MS/MS) with electro spray ionization (ESI+). Modified QuEChERS methods with 1 % ethyl acetate in acetonitrile involved in the extraction of profenofos residues from green pods and mature dry grains. Results: The limit of detection and limit of quantification (LOD and LOQ) were 0.002 and 0.006 µgg-1, respectively. The recovery ranges from 88.75 to 101.36 % for the green pods and 88.34 to 98.77 % for mature dry grains with relative standard deviation (RSD) was in the range of 0.99 to 4.05 %. The field study was conducted to investigate the dissipation kinetics of profenofos in pigeonpea. Two applications of profenofos 50 % EC at 500 and 1000 g a.i.ha-1 at 15 days intervals in pigeonpea at the time of pod formation recorded initial deposits of 20.28 and 41.64 ìgg-1 in the green pod, respectively. At15 days after application, residues gradually dissipated to the level of 0.78 and 1.98 µg g-1 accounting to the loss of 96.15 and 95.58 % at 500 and 1000 g a.i. ha-1, respectively. The half-life values were 5.18 and 5.93 days. Hazard index (HI) was found less than 1 at 25th and 35th day after application at 500 and 1000 g a. i. ha-1, respectively.

“…Comprehensive analysis of two year's data from the experiment conducted during 2018-19 and 2019-20. The result of application of both seed treatment and foliar sprays with insecticides was found to be significantly elevated to the control ( The most common vector for MYMV is whitefly which was effectively managed by Imidacloprid, Spinosad (Yadav and Singh, 2014), and dimethoate (Yadav et al, 2015). For minimizing the whitefly population, scheduled spray of imidacloprid on 25 and 40 DAS was most effective found.…”

“…Many researchers have advocated using chemicals to control sucking pests in order to effectively reduce their population [4,5,6]. However, because the continuous and widespread use of insecticides from the same class has led to issues with resistance, negative effects on parasites and predators, residue hazards for people and animals, and environmental pollution [7].…”

Aim: The growing concern for environmental safety and the demand for pesticide residue –free food worldwide have evoked interest in pest management through the use of botanicals, which offers a good alternative to manage the insect pests in an eco-friendly manner. This research was carried out to study the efficiency of botanicals on the aphid population in lablab under organic production system. Study Design: The study was carried out in Randomized Block Design (RBD) with eight treatments and three replications. Place and Duration of Study: The study was carried out at College Orchard, Department of Vegetable Science, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore during 2021 - 2022. Methodology: The study was performed using chilli extract with three concentrations (2.5, 5.0 and 7.5%) and compared with other botanicals such as neem oil, neem seed kernel extract, garlic extract and panchagavya. The aphid population was counted visually before and 1, 3, 5 and 7 days after spraying. Results: The results showed that after 7 days spraying 95.81 per cent of aphid population was reduced in T3 (7.5% chilli extract) followed by T2 & T1 (5 % & 2.5%) with a population reduction to the level of 95.62 and 91.54 per cent, respectively. This was followed by neem oil with a reduction of 83.50 per cent followed by garlic extract (79.74%), neem extract (76.94%) and panchagavya (62.81%). The inflorescence infestation was also lower in T3 (4.94) which were compared to control. Conclusion: The application of chilli extract resulted in reduction of aphid population in lablab under organic cultivation. Infloresecence infestation was also recorded minimum in chilli extract treated plots. The chilli extract is non-toxic to humans and does not harm the environment and hence this can be utilized as an alternative to chemical pesticides.
