Problems solved by technology

[0003] Some patents in the prior art have disclosed the control effect of the mixture containing nicosulfuron on common weeds such as barnyard grass, crabgrass crabgrass, goosegrass, quinoa, purslane, and amaranth, such as CN1428080A, CN1390456A .
Bromoxynil mixed with 2,4-D butyl ester has been reported to have a significant synergistic effect on commelina, but it is ineffective against gramineous weeds

Abstract

The invention relates to a herbicide composition, wherein component A is nicosulfuron, component B is bromoxynil, and component C is a hormone herbicide; and the weight portion ratio of the three active components is 1 to 1-30 to 1-30. The hormone herbicide is 2, 4-D, 2-methyl-4-chlorophenoxyacetic acid, dicamba or fluroxypyr and so on. The herbicide composition has obvious synergistic action and is particularly suitable for preventing and killing grassy and broad leaved weeds in corn fields.

Description

technical field [0001] The invention belongs to the field of agricultural herbicides, in particular to a herbicide composition. Background technique [0002] At present, the herbicides used in cornfields in my country mainly include the mixed use of atrazine and amide herbicides before emergence, and the application of atrazine, 2,4-D butyl ester, sodium dimethyltetrachloride, bromoxynil, and sulcotrione after emergence. , Nicosulfuron et al. Because atrazine has a long residual effect in the soil, it is not conducive to crop rotation stubble, and the herbicide used for soil treatment has poor efficacy or even ineffective in drought, and its weeding effect is greatly affected by soil moisture. However, 2,4-D butyl ester, dimethyltetrachloride sodium salt, bromoxynil, etc. in the stem and leaf treatment herbicides only have good control effects on broad-leaved weeds, but are invalid for gramineous weeds; Although it is effective on grasses and broad-leaved weeds, its reactio...
