Abstract

The invention relates to the field of agricultural weedicide and in particular relates to weedicide for corn fields. The weedicide is prepared from the following raw materials: sodium methyl-4-chlorophenoxyacetate, 2,4-dichlorophenoxyacetic acid B1, isooctyl 2,4-dichlorophenoxyacetate B5, tribenuron or triasulfuron, a synergist, a disintegrating agent, a wetting agent, a dispersant and filling; the weedicide for the corn fields, provided by the invention, has a long working life and a wide weeding spectrum; the weedicide has ideal effect on monocotyledonous weeds no matter whether the weedicide is used for carrying out pre-emergence treatment or post-emergence treatment; the use amount of the weedicide is less, basically no soil residues are formed and the weedicide is safe to use; the weedicide has a weeding effect on resistant weeds, can be used for pre-emergence treatment of the corn fields and can also be used for post-emergence stem leaf spraying treatment, and the planting cost is saved.

Description

technical field [0001] The invention relates to the field of agricultural herbicides, in particular to a herbicide used in corn fields. Background technique [0002] Corn is currently the crop with the largest planting area in my country. The sown area of ​​corn fields is nearly 500 million mu, and the output is about 190 million tons, accounting for 35% of the total grain output. At present, the market demand for corn in my country is showing an increasing trend, and the weeding hazards are One of the important measures to increase corn yield. There are many kinds of herbicides currently used in cornfields, such as acetochlor, atrazine, etc. Acetochlor herbicides have a short residual period in soil and are easily degraded in plants. Acetochlor mainly controls annual gramineous weeds, and is less effective against dicotyledonous weeds; atrazine herbicides are effective against broad-leaved weeds, but they have a long persistence period in the soil, and when the dosage is high...
