Description
Technical Field
The invention belongs to the technical field of pesticides, and relates to application of a composition containing bromofenoxanil and diafenthiuron to crop pests.
Background
The brobendiamide was developed by basf together with Mitsui Chemistry (MCAG), and the mechanism of action was novel. The demethylation-bromofenoxaprop-p-fluorobenzenediamide generated by metabolism of the bromofenoxaprop-p-fluorobenzenediamide has non-competitive resistance to GABA receptor antagonists, is a novel insecticide component classified into the 30 th family by the international insecticide resistance action committee, has no cross resistance with the existing insecticide, has excellent efficacy in controlling various chewing mouthpart pests, can control lepidoptera, coleoptera, thrips and other pests aiming at commercial crops and field crops, and can be used for controlling pests such as termites, ants, cockroaches, flies and the like in public health. The component of the brofenthiuron bisamide can be developed to be used for preventing and controlling the golden insects in grain seed coating agents.
Diafenthiuron is a novel thiourea insecticide and acaricide with high efficiency, which destroys the basic functions of the nervous system and inhibits the synthesis of chitin of pests by interfering the energy metabolism of the nervous system. Has contact poisoning, stomach poisoning, systemic absorption and fumigation effects, and has ovum killing effect. Converting into substance with insecticidal activity under ultraviolet light, and has strong activity on pests with severe drug resistance on vegetables. Can be used for preventing and treating aphid, whitefly, leafhopper, noctuidae pests and mites on various crops and ornamental plants.
Because crops often have various insect pests, and most medicaments can only control one or a certain type of pests, the effect of simultaneously controlling different pests can be achieved by the mixed use of two or more medicaments with different action mechanisms; can also improve the control effect and quick-acting property of the medicament, achieve the purposes of increasing the medicament effect and reducing the medicament resistance; can also improve the efficiency and reduce the medication cost.
