Problems solved by technology

[0002] Sulcotrione is used to control broadleaf and gramineous weeds in corn fields. Its oral, dermal and inhalation acute toxicity to mammals is very low, and it is safe to use, but its herbicidal spectrum is narrow, which is not conducive to the control of other types of weeds. weeds
[0003] Atrazine can be used before or after budding to control annual weeds in cornfields. It is mainly effective in controlling broad-leaved weeds in cornfields, but poor in gramineous grasses. can not be used
[0004] The pesticides mentioned above have their own advantages and disadvantages, and cannot completely and effectively control the occurrence of weeds in corn fields, which brings great inconvenience to agricultural production.

Abstract

The invention relates to a sulcotrione and atrazine mixed herbicide containing the active ingredients of sulcotrione and atrazine, the sulcotrione weight accounts for 11%, and the atrazine weight accounts for 29%; the sulcotrione and the atrazine are compounded with known auxiliary agents to prepare into conventional dosage forms such as powder, wettable powder, suspension emulsion, missible oil, granula preparations; the sulcotrione and atrazine mixed herbicide can prevent and eliminate most of gramineous weeds and broadleaf weeds from the seedling stage to the late development stage in cornfields in one time and can control weeds in the entire growth period of corn through the application of the mixed herbicide in one time. The mixed herbicide saves farming time, reduces the cost, enlarges the weeding spectrum, and has large synergistic and complementary effects.

Description

technical field [0001] The invention relates to a herbicide, in particular to a mixed herbicide of sulcotrione and atrazine for controlling weeds in corn fields. Background technique [0002] Sulcotrione is used to control broadleaf and gramineous weeds in corn fields. Its oral, dermal and inhalation acute toxicity to mammals is very low, and it is safe to use, but its herbicidal spectrum is narrow, which is not conducive to the control of other types of weeds. weeds. [0003] Atrazine can be used before or after budding to control annual weeds in cornfields. It is mainly effective in controlling broad-leaved weeds in cornfields, but poor in gramineous grasses. can not be used. [0004] The above-mentioned pesticides have their own advantages and disadvantages, and cannot fully and effectively control the occurrence of weeds in the cornfield, which brings great inconvenience to agricultural production. Contents of the invention [0005] The purpose of the present invent...
