Author(s): Sushil, Sushma Bisht, SS Yadav and Beena Kumari
Results of a field experiment conducted during 2015-16 to study degradation of novaluron in chickpea are reported. Novaluron (10 EC) at 37.5 (T1), 75 (T2) and 150 (T3) g a.i ha-1 at pod formation stage. Samples were drawn periodically at 0 (2h after spraying), 1, 3, 5, 7, 10, 15, harvest time and analyzed by GC-ECD. Novaluron dissipated following first order kinetics with half life 1.40-2.73 in green pods and 2.31-3.13 in soil. The average initial deposits of novaluron in green pods and soil were found to be 0.642, 1.705, 2.251 and 0.144, 0.186, 0.223 mg kg-1 at T1, T2 and T3, respectively. In case of green pods and soil 91 and 77% dissipation was observed at University recommended dose within 5 days after application. Harvest time grain and soil were found to be BDL.
