Bioefficacy and persistence of cyantraniliprole in kinnow mandarin under subtropical conditions of Punjab, India

Abstract Foliar application of cyantraniliprole @ 60 g a.i ha− 1 was found most effective and statistically superior to standard checks imidacloprid and thiamethoxam in reducing Diaphorina citri population in kinnow mandarin upto 14 days of treatment. Thus the nature and amounts of active metabolites of cyantraniliprole used in kinnow are set to ensure the safety of the consumers and environment. Hence residue of cyantraniliprole at effective dose i.e. 60 g a.i ha− 1 and double of effective dose i.e. 120 g a.i ha− 1. using 1000 L of water was estimated from kinnow fruits and soil. The average initial deposit of cyantraniliprole in kinnow fruits were 0.254 and 0.415 mg kg− 1 which dissipated to the extent of 95.28 and 95.15% in the respective doses after 10 days and to below detectable limits after 15 days of spray. The residue of cyantraniliprole in soil was found below detectable limits after 10 days of spray. It is concluded that cyantraniliprole can be used in D. citri management programme in kinnow mandarin and the pre-harvest interval recommended for safe consumption of kinnow fruits was observed to be 15 days.
