Abstract

The invention relates to the field of cabbage pest control and application thereof, and provides a binary compound insecticidal composition containing pyridine quinazoline. The binary compound insecticidal composition comprises an effective component A and an effective component B. The effective component A is pyridine quinazoline, the effective component B is one of thiacloprid, acetamiprid and Paichongding, the part ratio of pyridine quinazoline to thiacloprid is (1-80): (80-1). The dosage form of the insecticidal composition is one of a suspending agent, a water dispersible granule, wettable powder and an emulsion in water. According to the invention, the pyridine quinazoline and the thiacloprid are compounded, such that the insect pest control effect is effectively improved, the insect pest killing range is effectively increased, the abuse of various large-dose pesticides to kill beneficial insects is avoided, a significant synergistic effect is achieved within a certain ratio range, and an excellent control effect is achieved on the insect pests on crops; and meanwhile, the insect pests can be effectively prevented from generating obvious drug resistance, the use amount of pesticides is reduced, pollution to the environment is effectively relieved, and the insecticidal composition has high social use value and good application prospects.

Description

technical field [0001] The invention relates to cabbage pest control and the application field thereof, in particular to a binary compound insecticidal composition containing pyridinequinazoline. Background technique [0002] Pyridinequinazoline is a new type of quinazoline insecticide. Its mechanism of action is to prevent or interfere with the ability of pests to eat and crawl until the pests slowly starve to death. It is mainly used to control aphids and whiteflies on crops such as vegetables, fruit trees and tea. The piercing and sucking mouthpart pests such as worms, scale insects, leafhoppers and thrips can significantly reduce the spread of viral vectors. The compound can completely penetrate the leaf surface, and can also effectively control and control the pests that prey on and live under the leaf surface. [0003] Thiacloprid is a new type of chloronicotinoid insecticide with special effects on sucking and chewing mouthpart pests. The mechanism of action is diff...
