[0002] 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
[0003] 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
[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-atrazine mixed herbicide for controlling corn field weeds. The contained effective ingredients include 10% (weight) of sulcotrione and 30% (weight) of atrazine. The sulcotrione, the atrazine and known assistants are compounded into preparations of conventional forms, with the preparations including powder, wettable powder, suspoemulsions, missible oil and granules. The sulcotrione-atrazine mixed herbicide can control the majority of grassy weeds and broadleaf weeds in corn fields from a seedling stage to a late growth stage at one time. One time drug application can control the weeds of a whole corn growth period, so that the farming time is saved, the cost is reduced, the weed control spectrum is enlarged, and a large synergistic and complementary effect can be achieved.

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] 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. [0003] 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. [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...
