Abstract

The invention discloses a corn field composite herbicide and a preparation method thereof. The composite herbicide comprises the following components in percentage by weight: 0.05-35% of isoxaflutole, 0.03-35% of thiencarbazone-methyl, 0.02-35% of mesotrione, 5%-20% of an additive and 45%-88% of a solvent and / or a carrier. The corn field composite herbicide has the beneficial effects that after the isoxaflutole, the thiencarbazone-methy and the mesotrione are compounded, can complement the respective advantages with one another, and expand the herbicide controlling spectrum, show obvious synergism, and especially have very good effects on swart weeds which are difficult to prevent and control, such as bermuda grass, paspalum distichum, and para grass; meanwhile, the composite herbicide is easy to degrade, is short in residue time in soil, has the good safety to corn and afterreap crops, and delays and controls the drug resistance of weeds and the succession of the field weed communities.

Description

technical field [0001] The invention relates to a herbicide, in particular to a cornfield compound herbicide containing various organic compounds and a preparation method thereof. Background technique [0002] Corn is the largest economic crop in my country, and effective control and control of weeds in cornfields is one of the main methods to increase corn yield. For the main weeds in the corn field: velvetleum, quinoa, Kochia, pigskin, nightshade, amaranthus, willow-leaved Polygonum, ghost needle grass, purslane, chickweed, fennel, cocklebur, and amaranth Annual broad-leaved weeds such as Acanthus chinensis, Sorrelleaf Polygonum, and Popona, as well as annual gramineous weeds such as crabgrass, barnyardgrass, goosegrass, Qianjinzi, giant foxtail and foxtail, etc. At present, amide herbicides are mainly used Such as acetochlor, alachlor, butachlor, metolachlor, etc. are used for control, but due to long-term continuous use, weeds develop resistance, and malignant weeds suc...
