Abstract
The invention relates to an insecticide composition containing tolfenpyrad and cyantraniliprole, belonging to the field of chemical control. The insecticide composition contains the effective components including tolfenpyrad and cyantraniliprole, and auxiliaries, and has an excellent synergistic effect to the control of rice leaf folders. An indoor bioassay experiment shows that the synergistic effect ratio of the insecticide composition on the rice leaf folders is (80 to 1)-(1 to 80). A field experiment shows that different dosage forms of the composition containing the two components present excellent control effects on the rice leaf folders, and the control effect on the rice leaf folders is 88% or above after the composition is used for 7 days, is 91% or above after the composition is used for 14 days and is remarkably higher than the control effect of a common insecticide, namely Coragen. The insecticide composition has the characteristics that the synergistic effect is remarkable, the control effect is good, the dosage is low, and the composition is safe to the environment and target organisms and has multiple treatment effects; and the composition can be used for simultaneously treating other insect attacks (such as striped rice borer and tryporyza incertulas) on the rice and has a very good effect of delaying the drug resistance of the rice leaf folders to chlorantraniliprole.
