Herbicidal composition containing cyclo-pyrazole fluridon and pyraflufen-ethyl

Abstract

The invention relates to a herbicidal composition containing cyclo-pyrazole fluridon and pyraflufen-ethyl. The herbicidal composition is mainly characterized by comprising two effective active constituents of cyclo-pyrazole fluridon and pyraflufen-ethyl, wherein the mass percent of cyclo-pyrazole fluridon and pyraflufen-ethyl in the composition is 1%-90%, preferably 2%-80%, and the mass ratio of cyclo-pyrazole fluridon to pyraflufen-ethyl is (1-100):(1-100), preferably (10-30):(1-5). The effective constituents of the herbicidal composition have the significant synergistic function, so that the herbicidal spectrum is enlarged, the pesticide application dosage is reduced, generation and development of the drug resistance of the weeds can be relieved, and social significance and high economic value are achieved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition containing cifluzazone and metazafen, which is used for controlling weeds in wheat fields. Background technique [0002] Wheat is an important food crop in my country, and it plays a vital role in solving people's food and clothing and social and political stability. With the continuous improvement of the mechanization level of agricultural production, the use of herbicides to control weeds in wheat fields has become An indispensable step in the current agricultural production process. However, long-term continuous high-dose use of a single species or a single mode of action of chemical herbicides is likely to cause problems such as weed resistance and resistance evolution. Reasonable compounding or mixing of herbicide compounds has the advantages of expanding the spectrum of weeds, improving the control effect, delaying the occurrence and ...

AI Technical Summary

Problems solved by technology

In practical application, it is found that pyraclofen has excellent control effects on pig worms, big bowl flowers, quinoa, chickweed, etc., but the control effect on broad-leaved weeds such as Artemisia solani, shepherd's purse, and lacquer is average, and it is not effective on Maijiagong. , Nied Hucai, and Buddha Seat have poor control effects, and basically have no effect on grass weeds

In addition, pyraclofen has poor herbicidal thoroughness
