Composition of corn field herbicides

Abstract

The invention belongs to the field of pesticide mixing, and discloses a composition of corn field herbicides. The composition is a suspoemulsion, a water suspending agent or an oil suspending agent composed of A, B and C herbicide compounds serving as active ingredients, and the active ingredient content of the composition is 5 to 60 percent; A is mesotrione, B is one or more of triazine herbicides, and C is one or more of amide herbicides, wherein the composition contains one herbicide compound A, at least one herbicide compound B selected from the following compounds and at least one herbicide compound C selected from the following compounds; and according to the formula, the composition is ground under high pressure, emulsified and dispersed into the suspoemulsion, the water suspending agent or the oil suspending agent according to different proportions, and is used for preventing and killing weeds in corn fields at the post-emergence stage.

Description

technical field [0001] The invention belongs to the field of pesticide mixing, and relates to suspoemulsion, water suspension and oil suspension composed of effective component (A), at least one specific herbicidal compound (B) and at least one specific herbicidal compound (C). Background technique [0002] With the adjustment of agricultural structure, the further development of animal husbandry and the expansion of exports, the demand for corn has increased significantly. At present, more than 80% of domestic corn is mainly used for feed, starch, alcohol, monosodium glutamate processing and pharmaceuticals. In recent years, with the strengthening of environmental protection, the reduction of vehicle exhaust emissions and the use of ethanol instead of gasoline have become a trend to develop the ethanol industry. Its main raw material adopts corn, which will promote the expanded planting of corn, so it has more development potential than other crops. [0003] Corn is one of...

Problems solved by technology

The application area of ​​herbicides in cornfields in my country is 5.62 million hm2, accounting for only 1 / 4. The herbicide varieties in my country's cornfields are only atrazine, mecitrione, alachlor, acetochlor, metolachlor, Pretilachlor, thiasulfuron, nicosulfuron, trifluralin, 2,4-D, glyphosate, paraquat, etc. more than 10 species, of which the long-residual herbicide atrazine is used too much, which is harmful to subsequent crops. Influenced by the high multi-cropping index of crops in our country and the complicated crop rotation and intercropping, the long-term use of this single herbicide has huge hidden dangers

In addition, in the case of frequent droughts in our country, the efficacy of herbicides related to rainfall is unstable. When the application is dry, the efficacy is poor or ineffective. Sometimes heavy rains cause phytotoxicity.
