Abstract

The invention discloses a herbicide composition containing topramezone, belonging to the technical field of pesticides. The herbicide composition comprises a raw medicine prepared by compounding topramezone and a herbicide B, wherein the ratio of the topramezone to the herbicide B is (1-80):(1-80); and the herbicide B is any one of the following herbicides: fenoxaprop, fenoxaprop-p, isoproturon, diclofop-methyl, chlortoluron, methabenzthiazuron, imazamethabenz, tralkoxydim, difenzoquat, flampro, flampro M, pendimethalin, primisulfuron and the like. The herbicide composition disclosed by the invention is prepared by compounding topramezone and any one of the herbicide B; and the composition has the advantages of long duration, wide herbicide controlling spectrum and obvious weed control synergism, and overcomes the shortcomings of high cost and short duration by using topramezone only in the prior art.

Description

technical field

[0001] The invention relates to the technical field of pesticides, in particular to a herbicide combination containing fenfentrazone. Background technique

[0002] The crop yield is reduced due to the damage of weeds, so it is necessary to apply a large amount of herbicides every year for weed control to recover the loss of crop yield. In recent years, the harm of weeds to crops has become more and more serious, and due to the abuse of herbicides, weeds have become more and more resistant to pesticides, resulting in a decrease in the weed control effect year by year.

[0003] Fenzazone: It belongs to benzoylpyrazolone herbicide, which can be absorbed by roots, seedlings and leaves after the treatment of stems and leaves after emergence. It is transmitted to the top and base of the plant to the meristem, and inhibits p-hydroxyphenylacetone Ester dioxygenase (4-HPPL), which inhibits and disrupts the biosynthesis and function of carotenoids and chlorophyll, lea...
