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 weeding composition containing bentazone, acifluorfen-sodium and haloxyfop-r-methyl. The weeding composition comprises main effective components of bentazone, acifluorfen-sodium and haloxyfop-r-methyl in a mass ratio of 1-80:1-80:1-80. The weeding composition of the invention has substantial effects on application to weeding after seedling in soybean field, especially application to control of gramineae weeds, broad leaf weeds and nutgrass flatsedge in the soybean field. Compared with a single dose, the weeding composition of the invention, on the premise of enhancing drug effect, delays weed resistance, has a wide weeding spectrum and a long persistent period, and is safe to soybean and later 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 high-efficiency flurifop-pyl. 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...
