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 clethodim which serve as the main effective components and are in a mass ratio of 1-70:1-80:1-80. The herbicidal composition of the invention can be used in soybean field post-seedling weeding, and especially presents an obvious effect when applied to control of various gramineous and broadleaf weeds in soybean fields. In the precondition of improving the herbicide effect, the herbicidal composition of the invention, compared with a single agent, can delay weed resistance and has broad herbicidal spectrum, long persistent period as well as security to soybean and succeeding crops.

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, imazethapyr and clethodim. 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, and causes ph...
