Abstract
The invention belongs to the field of pesticides, and relates to a binary composition and an application thereof. The binary composition contains an active component a and an active component b, the active component a is a compound A, and the active component b is selected from compounds with insecticidal or bactericidal activity; and the compound A is a compound with the structural formula shown in the specification, and a weight part ratio of the active component a to the active component b is 100:1-1:100. The composition has the advantages of synergy, control spectrum enlargement and the like, and can be used for controlling pests and pest mites, and plant diseases induced by various fungi, bacteria, threadworms and viruses.
Description
technical field [0001] The invention belongs to the field of pesticides and relates to a binary composition and its application. Background technique [0002] The compound A (structural formula is as follows) can be used to control various pests, especially has outstanding control effect on Lepidoptera pests. The compound has both therapeutic effects on various pests of Coleoptera, Diptera, Thysanoptera, Homoptera and the like. Chinese invention patent CN101333213A discloses a 1-substituted pyridyl-pyrazole amide compound and its use for controlling pests and diseases, wherein compound 1.25 is compound A. [0003] [0004] In the history of pesticide development, the mixed use of pesticides has been developed along with the development of pesticides. Usually a commercial product with excellent effect will be accompanied by many related mixed drug varieties, and the market value created by the mixed drug product is often greater than that of the single drug product.
