Author(s): Usha Kabadad and SK Gali
Abstract: A field experiment was conducted at main agricultural research station, Dharwad during rabi 2015-16 to study the persistence of chlorantraniliprole residues in cabbage (Brassica oleracea L.) and soil, following four application of chlorantraniliprole at0.20ml L-1 (single dose) and 0.40 ml L-1 (double dose) g a. i. ha-1. Analysis of cabbage samples using UPLC revealed that the chlorantraniliprole residue persisted up to two days in both single and double dose after the last spray. The initial deposits of chlorantraniliprole residues in cabbage heads on 0 day (2hrs after last spray) were 0.81 mg kg−1 in single dosage and 2.00 mg kg−1 in double dosage of the chemical and reached below detectable limit by 3rd day, showing 100 per cent dissipation of chlorantraniliprole at both the dosages. Soil samples collected after 15 days of last spray, did not show the presence of chlorantraniliprole residue. Based on complete dissipation of the insecticide the waiting period for harvest of crop was found to be five days after the last spray.
