Composite herbicide for wheat fields

Abstract

The invention relates to a composite herbicide for wheat fields, and the composite herbicide comprises the following ingredients by weight: 10% of tribenuron methyl, 5.6% of 2-methyl-4-chlorophenoxyacetic acid sodium (MCPA-Na), 4.4% of sodium lignosulfonate, 30% of dairy 500, 15% of farming-benefiting penetrating agent A, 10% azone, 12% of kaolin and 13% of diatomite. The herbicide retains high activity of sulfonylurea herbicides, but also greatly reduces the use amount, and has the substantial advantages of being wide in herbicidal spectrum, high in herbicidal activity, safe to use, and free of phytotoxicity effects on sensitive next-stubble crops.

Description

technical field [0001] The invention relates to a herbicide, especially a compound herbicide suitable for use in wheat fields. Background technique [0002] At present, sulfonylurea herbicides are mostly used for weeding wheat fields. Although this herbicide has high herbicidal activity, it has a long residual effect period and a slightly high dosage, which will cause phytotoxicity to the next crop. Contents of the invention [0003] In order to solve the above problems, the present invention provides a compound herbicide for wheat fields, which has superior control effects on broad-leaved weeds and some grass weeds, is safe to use, and has no adverse effects on the next sensitive crops. Purpose. [0004] The compound herbicide for wheat fields of the present invention is composed of the following components by mass percentage: Tribenuron 10%, Sodium Dimethyltetrachloride 5.6%, Sodium Lignosulfonate 4.4%, Nongru 500 30%, Yinong Penetrant A15 %, Azone 10%, Kaolin 12%, Dia...
