Embodiment 1

[0014] According to the effective component weight ratio of mesotrione / dimethyltetrachloride sodium salt = 80 / 1, mesotrione and dimethyltetrachloride sodium salt are homogeneously compounded, and the two components are mixed and used separately Used alone to carry out drug effect contrast test, the results are shown in Table 1.

Embodiment 2

[0016] Mesotrione and dimethyltetrachloride sodium salt are homogeneously compounded according to the ratio of mesotrione / dimethyltetrachloride sodium salt=4 / 1 according to the weight ratio of the effective components, and the drug effect comparison test results are shown in Table I.

Embodiment 3

[0018] According to the effective component weight ratio of mesotrione / dimethyltetrachloride sodium salt = 75 / 28, mesotrione and dimethyltetrachloride sodium salt are homogeneously compounded, and the drug effect comparison test results are shown in Table I.

Abstract

The invention discloses a herbicidal composition, which is formed by compounding mesotrione and powder of MCPA-sodium salt, wherein effective constituents of the herbicidal composition are the mesotrione and the MCPA-sodium salt, and the weight ratio of the effective constituents in the composition is as follows: the ratio of the mesotrione to the MCPA-sodium salt is between 1 / 80 and 80 / 1. The herbicidal composition makes up the disadvantages of poor effect and narrow herbicidal spectrum of the prior herbicide in corn and sugarcane fields, can prevent and remove various weeds in the sugarcane field at one time, has good herbicidal effect, reduces using amount, delays the generation of drug resistance of the weeds, and is environment-friendly, time-saving and labor-saving.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a herbicidal composition for broad-spectrum control of weeds in corn and sugarcane fields, and belongs to the field of agrochemical technology. Background technique [0002] People have already begun to devote themselves to the research and development of herbicides in corn and sugarcane fields. It can be found through investigation that many herbicide products that are safe for corn are more sensitive to sugarcane. The application number is 200610053858X, and the Chinese invention patent application titled "A Herbicide for Controlling Weeds in Sugarcane Fields" discloses a herbicide for sugarcane fields, which belongs to herbicides containing heterocyclic compounds, and its active ingredient is diuron , sodium 2-methyl-4-chloride and ametrazine, the range of mass fractions is: 5-25% for diuron, 5-20% for sodium-2-methyl-4-chloride; 10-50% for arazine. The compound herbicide has a ce...
