Problems solved by technology

However, sulcotrione has relatively poor control effect on gramineous weeds, and its herbicidal spectrum is relatively narrow, so it is subject to certain restrictions in use.
[0005] At present, herbicides in cornfields are limited by the safety of crops, and their herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in cornfields. Too long effective period, excessive dosage or uneven application will easily cause residual toxicity to current crops or subsequent crops

Abstract

The invention discloses a herbicidal composition containing bentazone, dicamba and sulcotrione. The herbicidal composition takes bentazone, dicamba and sulcotrione as main active ingredients, wherein the mass ratio of bentazone to dicamba to sulcotrione is (1-80):(1-80):(1-80). The herbicidal composition has an obvious effect on postemergence weed control in corn fields, especially on controllingvarious grass and broadleaf weeds in the corn fields. Compared with the single agent, the herbicidal composition delays weed resistance, has wide herbicidal spectrum and long efficacy duration and does no harm to the corns and the aftercrops on the premise of improving the pesticide effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and specifically relates to a ternary compound herbicidal composition of bentazone, dicamba and sulcotrione, which can be applied to post-emergence weeding in corn fields. Background technique [0002] Mechasong, also known as Paicaodan and Bendasone. Chemical name: 3-isopropyl-(1H)-benzo-2,1,3-thiadiazin-4-one-2,2-dioxide, the herbicide is a contact type selective post-emergence Herbicides, used in seedling stem and leaf treatments, act by leaf contact. When used in dry fields, it first penetrates into the chloroplast through the leaf surface to inhibit photosynthesis. The use of paddy fields can not only penetrate through the leaves but also absorb through the roots, and then transmit to the stems and leaves, which strongly hinders the photosynthesis and water metabolism of weeds, causes nutrient starvation, and causes physiological dysfunction and...
