Fenoxaprop.Flucarbazone composite herbicide

Abstract

The invention relates to a Fenoxaprop.Flucarbazone composite herbicide, belonging to the technical field of pesticide and aiming to solve the technical problem of providing a Fenoxaprop.Flucarbazone composite herbicide for preventing and killing wheat field resistance grass family weeds. The technical key point is that the composite herbicide is prepared by the following raw materials and assistants in mass percentage: 0.1-90 of Fenoxaprop, 90-0.1 of Flucarbazone, 5-7 of dispersant, 1-3 of wetting agent, 3-5 of disintegrant, 2-3 of adhesive and balance of carrier. The inventive herbicide has obvious weeding effect on resistance grass family weeds, obviously superior to two single preparations and other composite preparations; meanwhile, the herbicide has broad weeding spectrum, can efficiently prevent and kill annual resistance grass family weeds without influencing the crops to be grown; the herbicide is environment-friendly and is an ideal herbicide for treating post-sprout stems and leaves of wheat at present.

Description

technical field [0001] The invention relates to a compound herbicide for post-emergence stem and leaf treatment of wheat, in particular to a compound herbicide of fenoxaprop-ethyl-flucarbasulfuron-methyl. technical background [0002] Wheat is one of the main food crops in northern my country. The perennial planting area in China is more than 30 million hectares, second only to rice planting area. The area of ​​wheat field weed damage accounts for more than 30% of the total planting area, of which more than 8% are severely damaged, and the yield is generally reduced by more than 15%, and in severe cases, the harvest may be completely eliminated. Therefore, the proportion of herbicides used in domestic wheat fields is almost 100%, and the dosage is very large. Weeds in wheat fields can be divided into broadleaf weeds and grass weeds. Among them, broad-leaved weeds are relatively easy to control, while grass weeds are more difficult to control because they belong to the gras...

AI Technical Summary

Problems solved by technology

According to experiments and practical application in the field, these herbicides can only control some of the grass weeds, but the effect on other grass weeds is not ideal

In this way, there is an urgent need for herbicides that can control resistant grass weeds in wheat fields, which will not affect the safety of subsequent crops and are environmentally friendly herbicides. At present, such herbicides are rarely seen in my country.
