“…The phytotoxic effects of chlorantraniliprole 18.5% sc on brinjal leaves, shoots, and fruits were measured using the technique described by Kodandaram et al (2017) at the recommended (40 g a.i./ha) and double the recommended (80 g a.i./ha) concentrations.…”

Brinjal shoot and fruit borer (BSFB) (Leucinodes orbonalis (Gennadius)) causes significant economic harm to brinjal (Solanum melongena L.) production. The present study was carried out at research farm of ICAR-Indian Institute of Vegetable Research, Varanasi, Uttar Pradesh to standardize the optimum dose of chlorantraniliprole 18.5% sc (CAP) to manage BSFB under field conditions and to quantify the residue of CAP in brinjal for food safety. Three CAP doses (20, 40, and 80 g a.i./ha) along with an old generic insecticide (cypermethrin 25% ec @50 g a.i./ ha) as a check and an untreated control were examined during 2017–19. CAP applications of 40 and 80 g a.i./ha were similarly efficient against BSFB and resulted in a significantly higher yield of brinjal fruit. The population of borers was reduced significantly in the treatment, CAP @40 g a.i./ha as compared to the untreated control. Phytotoxic effects of chlorantraniliprole 18.5% sc were not observed. Natural enemies of the brinjal ecosystem, viz. predatory pentatomid bug [Eocanthecona furcellata (Wolff)], ladybird beetle [Coccinella septempunctata (Linn.)], and spider were unaffected by CAP treatment. When CAP was applied @40 and 80 g a.i./ha, chlorantraniliprole degraded from brinjal fruits with half-lives of 4.85 and 7 days, and pre-harvest intervals of 7 and 10 days were prescribed, respectively. Even at greater application doses, residues in a person's meals were found to be lower than the maximum permissible intake (24.96 mg/person/day) in day-zero samples. Chlorantraniliprole @40 g a.i./ha can be an effective alternative to the conventional insecticides against BSFB in brinjal, ensuring quality, sustainability, and safety.

“…The data regarding the consumption of chemical pesticides, which was projected to reach 70668 metric tons in 2020-21 (MoA&FW, 2021) [8] , clearly illustrates the rising need for chemical pesticides. After chili, eggplant receives the most pesticide spraying out of the 13-14% of vegetables in India (Kodandaram et al, 2013) [6] . However, its careless use has detrimental effects on the environment and the economy.…”

The crop of brinjal is vulnerable to several pests, illnesses, and insects. The growers of eggplants employ fungicides and chemical insecticides in a combination of two to three. Insect resistance to pesticides and residual issues arise from the continuous and careless application of insecticides. The health risks associated with pesticide residues in food, whether short-or long-term, are dose-dependent. The amount of pesticide consumed per kilogram of body weight determines whether or not there may be health risks. The Food Safety and Standards Authority of India sets the maximum residue limits (MRLs) values for various pesticides in various crops in our nation (FSSAI). Using more recent pesticides is safer in terms of toxicity to non-targets, safer for the environment, and also prevents the target pest from developing resistance. Integrated pest management, or IPM, is one of the most important and environmentally safe solutions to boost crop yield in the nation while ensuring the sustainability of the brinjal crop. Farmers must decide which pesticide to use and how to apply it correctly. Each pesticide label that comes with the formulation package details the amount to be used, when and how to apply it, as well as any necessary precautions to take both during and after application. Teaching farmers to use pesticides safely is the biggest challenge. Building robust and efficient networks amongst farmers, extension agents, and research organizations is necessary to provide healthy food, minimize the use of pesticides, and save the environment.

“…With their awful shoots and fruit borer, these pests can cause significant crop losses. It damages tender shoots and fruits, reducing yield by up to 90% in different country locations [13,14]. To manage the population of pests and raise the quality of brinjal crops, it is crucial to understand the seasonal activity of the pests and the environmental factors affecting their population dynamics.…”

The purpose of this study was to determine the effect of weather parameters on the infestations of shoot and fruit caused by brinjal shoot and fruit borer (Leucinodes orbonalis) (Lepidoptera; Pyralidae) during Kharif and Rabi seasons of two consecutive years. The findings showed that the shoot infestation began (5.35%) in 1st week of January and severed (30.85%) in 3rd week of February and 1st week of March in the first and second years. The shoot infestation was associated positively (r=0.267) with temperature but negatively with relative humidity and rainfall (r=-0.182 and -0.235). The fruit infestation (26.57% and 21.74%) began in the 1st week of February and gradually peaked (52.69 and 46.36%) in the 1st week of March. However, it was associated negatively with relative humidity (r=-0.773 and 0.747) and rainfall (r=-0.204 and -0.202) while positively with temperature during the rabi season of the first year. The same patterns of infestations were recorded in the next year. Compared to the Kharif seasons, shoot infestation started (7.65%) in 1st week of July and the highest (31.21%) in 3rd week of August. Additionally, it was associated negatively with temperature (r=-0.235) while positively with relative humidity and rainfall (r=0.060 and 0.677). The infestation of the fruit started (27.35 and 21.25%) in 1st week of August and steadily increased, reaching to peak (53.26 and 47.22%) in 1st week of September. Moreover, it was associated negatively with temperature (r=-0.500 and -0483) and positively with relative humidity (r=0.426 and 0.443). However, a negative association (r=-0.187 and -0.180) was found with rainfall. While in the second year, the same infestation patterns were recorded as the previous year, except rainfall was positively (r=0.0283 and 0.287) associated with fruit infestation. In conclusion, the weather affects the BSFB infestation significantly or non-significantly. This finding could be helpful for farmers in planning their cultivation practices for brinjal and pest management strategies to reduce the infestation caused by BSFB.
