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 quizalofo-P-ethyl. The weeding composition adopts the bentazone, the acifluorfen-sodium and the quizalofo-P-ethyl as main effective components, wherein a mass ratio of the bentazone to the acifluorfen-sodium to the quizalofo-P-ethyl is 1:60:1-60:1-60. The weeding composition provided by the present invention can be applicable for weeding in the soybean field after seedling, specifically provides significant effects for prevention and elimination of various grassy weeds, broadleaf weeds and papyrus in the soybean field. Compared to the single weed killer, in the premise of improvement of the efficacy, the weeding composition provided by the present invention delays the resistance generating of the weeds, and has wide weeding spectrum and long effective duration, and provides safeties for the soybean and the succeeding crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, especially the field of herbicides, and specifically relates to a ternary compound herbicidal composition of bentazone, imazethapyric acid and quizalofop-p-ethyl. 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...
