To observe the toxic effect of different insecticides on natural enemies cauliflower

Abstract

The invasion of the diamondback Muss was launched by the second SMW and peaked at the 8th SMW of the year. The maximum temperature showed a significant positive correlation with the larval population of diamondback Moth. Coccinellid Predator, Coccinellid septempunctata L. Significant positive correlation with populations of maximum and minimum temperature C. septempunctata Under a variety of new insecticides tested against diamondback, Spinosad has been found to be the most effective. This was discovered at the same time on Indoxacarb. The insecticides, emamectin-benzote, chlorantranillyprol and fipronil were moderately effective. Chlorphenapir, acephat and pyridalyl were least seen. Chlorantranillyprole, indoxacalb, flubendiamide, chlorphenapia, and emamectin-benzotes were moderately toxic, while spinosad and pyridalyl were proven to be toxic. Treatment was not significant even at Flubendiamide 39.35 SC. Minimum yields were pyridalyl 10 EC and Acephat 75 sp. The overall treatment was significantly better than the controls. Yield results resulted in yield results spinosad = indoxacarbs flubendiamide '\emomectin benzoat\clorantraniliproles\fipronil = chlorfenapyr-acephat = pyridalic control.
