Pymetrozine and isoprocarb insecticidal composition

Abstract

The invention relates to an insecticidal compound of pymetrozine and isoprocarb, which refers to a mixed insecticide that can efficiently prevent such pests with piercing-sucking mouthparts as a plant hopper and the like, and consists of the pymetrozine (effective ingredient I) and the isoprocarb (effective ingredient II); the weight ratio of I to II is 1:5 to 1:15, and the two can be mixed to prepare normal dosage forms, such as wettable powder, aqua, suspending agent, and the like; when in use, the mixed insecticide is diluted to a required concentration by adding water; and the mixed insecticide can be used for preventing agricultural pests, in particular to the pests with piercing-sucking mouthparts, such as the plant hopper and the like. The mixed insecticide has the advantages that (1) the mixing of the pymetrozine and the isoprocarb has significant synergistic effect on the plant hopper, thus improving the control effect; (2) the resistance of the pests against the single dose of the pymetrozine and the isoprocarb is delayed; (3) high-toxic pesticides are replaced, pesticide application is reduced, and environmental pollution and pesticide residues in food are decreased; and (4) compared with the single dose of the pymetrozine, the application cost is significantly reduced.

Description

(1) Technical field [0001] The present invention relates to the binary insecticidal composition that pymetrozine (hereinafter referred to as active ingredient I) and isoprocarb (hereinafter referred to as active ingredient II) are active ingredients, and its preparation can be used to control agricultural pests, especially planthoppers . (2) Background technology [0002] Pymertrozine, as the active ingredient I, belongs to triazinones with a unique mode of action. The action is characterized by the inhibition of the nerve center of feeding behavior, and interferes with normal feeding activities by affecting the nerve center regulation of fluid absorption. Leaf conduction activity on crops, and can move apically in the xylem and basally in the phloem; controls most pests of the Homoptera, especially Aphididae, Whiteflies (such as Bemisia tabaci), Leafhoppers And planthopper pests, suitable for vegetables, rice, cotton, fruit trees and a variety of field crops. Its validity...
