Abstract:
Field efficacy trials of five insecticides on cabbage caterpillar were conducted in order to select an effective and low-toxic drug for cabbage caterpillar control. The results showed that 30% indoxacarb and 10% cyantraniliprole solution had efficient controlling function, the average control efficiency of 1, 3, 7 d after treatment was 73.90%-89.91%; the next was 4.5% beta cypermethrin ME 1000 times, the average control efficiency of 1, 3, 7 d after treatment for which was 70.14%-76.99%. Therefore, it was recommended to alternately apply 10% cyantraniliprole SC 1000 times and 30% indoxacarb 3000 times, and to apply 4.5% beta cypermethrin ME 1000 times at suitable times for controlling cabbage caterpillar.
