Problems solved by technology

[0005] At present, herbicides in soybean fields are limited by the safety of crops, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely effectively control the occurrence of weeds in soybean fields. Too long, 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, acifluorfen-sodium and sethoxydim. The herbicidal composition treats bentazone, acifluorfen-sodium and sethoxydim as main effective components, and the mass ratio among bentazone, acifluorfen-sodium and sethoxydim is 1-60:1-60:1-60. The herbicidal composition of the invention which is used for postemergent weeding in soybean fields has a substantial effect when being applied to control various grassy weeds, broadleaf weeds, and sedges in the soybean fields. Compared with a single dose, the herbicidal composition of the present invention allows weed resistance delay, broad weeding spectrum, and long persistent period to be realized and has security to soybean and later crops on condition that the drug effect is improved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and in particular relates to a ternary compound herbicidal composition of bentazone, imazethapynic acid and sethenoxydim. The herbicidal composition can be applied to post-emergence weeding in soybean 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, an...
