Abstract
In the present study, dissipation and residue dynamics of tebuconazole in peanut plant and soil and final residue in peanut plant, kernel and soil were carried out. Tebuconazole was applied at recommended dose (187.5 g a. i. ha−1) and double recommended dose to cropped plots following two foliar applications at an interval of ~15 days between 40 and 60 days after sowing of peanut for two consecutive years. The dissipation experiments showed faster degradation of tebuconazole in plant (half-lives: 3.2–5.5 days; degradation rate constant: 0.1267–0.2142 day−1) than soil (half-lives: 9.6–12.5 days; degradation rate constant: 0.0553–0.0725 day−1) in both the season. At harvest, soil, plant and peanut kernel samples were found to contain no residues of tebuconazole irrespective of doses and season, indicating tebuconazole is safe from the human and environmental contamination point of view.
