Dissipation of combination product spirotetramat 120 SC + imidacloprid 120 SC (Movento Energy) in/on tomato

Abstract

Studies on the dissipation pattern of spirotetramat and imidacloprid in/on tomato fruits were undertaken by following three foliar applications at recommended and double the recommended doses of combination product spirotetramat 120 SC + imidacloprid 120 SC @ (75 and 150 g a.i./ha) at fruiting stage. Residues of spirotetramat and imidacloprid dissipated with half- life of 1.93, 1.37 and 1.40, 1.92 days, at both the doses respectively. The residues reached below quantification limit (BQL) on 5th day in spirotetramat and 7th day in imidacloprid at the recommended dose. Considering this, Pre-harvest interval (PHI) of 7 days can be suggested for combination product with reduced risk of insecticide residues in tomato.
