Problems solved by technology

[0011] 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 fenoxaprop-p-ethyl which serve as the main effective components and are in a mass ratio of 1-70:1-70:1-70. 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 weeds, broadleaf weeds and sedges in soybean fields. Compared with a single agent, the herbicidal composition of the invention, in the precondition of improving herbicide effect, 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 in particular relates to a ternary compound herbicidal composition of bentazone, imazethapyr and fenoxaprop-p-p-p. 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 structural formula is: [0003] [0004] The herbicide is a contact-type selective post-emergence herbicide, which is used for the treatment of stems and leaves at the seedling stage, and works through 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 h...
