Clodinafop-propargyl isoproturon compound herbicide

Abstract

The invention relates to clodinafop-propargyl isoproturon compound herbicide, belonging to pesticide technical field and mainly solving the technical problem that a clodinafop-propargyl isoproturon compound herbicide which can prevent and kill off gramineae weeds in wheat field but also can prevent and kill off broadleaf weeds is provided. The compound herbicide is prepared by the following raw materials and assistant by percent by weight: 4.5-12% of clodinafop-propargyl, 35-75% of isoproturon, 6-10% of dispersant, 1-3% of wetting agent, 3-5% of disintegrant, 2-3% of bonding agent, the balance carrier. The compound herbicide of the invention has obvious effect, is clearly superior to two single herbicides and is also clearly superior to other compound herbicides; the compound herbicide has wide herbicidal spectrum, can effectively prevent and kill off annual resistant gramineae weeds and broadleaf weeds, can prevent and kill off weeds of the whole growth period by once application, has no influence on next crop, is environmentally friendly and is ideal for wheat postemergence control.

Description

technical field [0001] The invention relates to a compound herbicide for post-emergence wheat, in particular to a compound herbicide of clodinafop-isoproturon. technical background [0002] Wheat is one of the main food crops in northern my country, and it is also an important feed crop. The annual planting area in my country is more than 30 million hectares, second only to the 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. At present, the main herbicides used in the post-emergence of domestic wheat fields are: Trisulfuron-methyl, Dicamba, Metsulfuron-methyl, Thisulfuron-methyl, Promethazol, Puma, etc., which are more effective in control...

Problems solved by technology

In this way, there is an urgent need for herbicides that can control both gramineous weeds and broadleaf weeds in wheat fields, without af
