“…Higher clothianidin dissipation in soil corresponds to higher organic carbon content (Zhang et al, 2018) and microbial growth (Kah et al, 2007). Moreover, the presence of clay content in the soil promotes the sorption of pesticides, rendering slow degradation of pesticides (Sahu et al, 2019).…”

Aim: To investigate the effects of farmyard manure addition, elevated CO2, soil sterilization, dry conditions, field-capacity conditions, and submerged conditions on clothianidin dissipation from the soil, as well as the effects of different pH levels, namely, pH 4.0, 7.0, and 9.2, on its dissipation from the aqueous solutions. Methodology: Samples were processed by the QuEChERS method from the soil and the dipping and shaking method from the aqueous solution, and then analyzed by Shimadzu HPLC-PDA. Results: The results revealed that clothianidin dissipation from soil and aqueous solution best fit first-order kinetics, with the coefficient of determination r2 value < 0.90. In the soil, varying clothianidin dissipation was recorded with significant impact and their decreasing dissipation rate was as follows: submerged conditions (t1/2103.7–107.5 days) > elevated CO2 (t1/2115.7–143.3 days) > farmyard manure addition (t1/2130.8–150.5 days) > field-capacity conditions (t1/2158.4–215.0 days) > dry conditions (t1/2250.8–334.4 days) > soil sterilization (t1/2342.0–376.2 days). In the aqueous solution, clothianidin dissipation was slow at pH 4.0 (t1/2430 days) but fast at pH 9.2 (t1/2273.6 d days). Interpretation: The findings suggest that clothianidin dissipation could be positively affected by FYM addition, elevated CO2, soil sterilization, dry conditions, field-capacity conditions, submerged conditions, and aqueous pH level in all the treatments. This information would help gain a better understanding of clothianidin dissipation in the environment for good agricultural practices,proper risk assessment, and monitoring guidelines.

The environmental effects and possible hazards of chlorantraniliprole, a frequently used insecticide, have recently come to the forefront. This article provides an in-depth look at novel methods for characterising chlorantraniliprole and its metabolites in soil, water, and plants. Various analytical procedures are covered in depth, including chromatographic methods, mass spectrometry, capillary electrophoresis, immunoassay-based procedures, and spectroscopic procedures. The difficulties and restrictions of chlorantraniliprole analysis, as well as its advantages, are discussed in length, along with sample preparation and extraction methods. The essay finishes by looking forward to several promising avenues of research and development, such as novel approaches, omics integration, and environmentally friendly analytic approaches. These findings aid in the advancement of chlorantraniliprole knowledge and open the path for more ecologically responsible pesticide application.

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.
