Herbicidal composition containing dichloroquinoline oxadiazon and clomazone

A technology of quinclorone and clomazone, which is applied in the directions of herbicides, algicides, biocides, animal repellents, etc., and can solve the compound combination of quinclorone and clomazone. There are no reports on the drug and its application, the synthesis is blocked, and the biosynthesis of carotenoids is affected, so as to delay the resistance of weeds, reduce the use amount, and improve the control effect.

Problems solved by technology

[0002] Chloroquinone, the chemical name is 2-(3,7-dichloroquinolin-8-yl)carbonyl-cyclohexanone-1,3-dione, and the CAS number is 1350901-36-8, which is independently developed by my country A new type of herbicide, which is mainly absorbed by weed roots, stems, and leaves to control grass crops, especially barnyardgrass, foxtail, crabgrass, and various broad-leaved weeds that are currently difficult to control. After applying the weeds, It is absorbed by the leaves or roots, moves up and down in the plant, and quickly spreads to the whole plant. It is an HPPD inhibitor. Its action is characterized by the absorption and conduction of weed roots and leaves. The synthesis of p-hydroxyphenylpyruvate dioxygenase leads to the accumulation of tyrosine, which hinders the synthesis of plastoquinone and tocopherol, which in turn affects the biosynthesis of carotenoids, and the weeds die after albinism
At present, there is no report on the compound composition and application of quinclomid and clomazone
