Efficacy of spirotetramat 11.01 + imidacloprid 11.01 SC against jassids, red mites and general predators in tomato
Abstract: Three different formulated doses (375, 500 and 625 ml ha-1) of spirotetramat + imidacloprid against jassids (Amrasca biguttula biguttula), red mites (Tetranychus urticae) and insect predators (coccinellids and spider) of tomato were tested in field condition during rabi summer seasons of 2017 and 2018. The other treatments were spirotetramat (500 ml ha-1), imidacloprid (375 ml ha- 1), fenazaquin (1250 ml ha-1) and acephate (390 g ha-1). The statistically at par maximum efficacy (against jassids and mites) and yield were observed in spirotetramat + imidacloprid at 500 and 625 ml ha-1. Even the lowest dose (375 ml ha-1) was also better responsive as compared to other treatments. Except acephate and fenazaquin, no harmful effect was recorded against above mentioned general insect predators. But considering economics, spirotetramat + imidacloprid at 375 - 500 ml ha-1 could be recommended in farmers’ field for managing jassids and mites in tomato.
