Problems solved by technology

However, its herbicidal spectrum is narrow, and it is ineffective against field bindweed, etc., and it is difficult to completely kill broad-leaved weeds in corn fields
[0011] At present, herbicides in cornfields are limited by the safety of crops, and their herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in cornfields. Too long effective period, 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, clopyralid and atrazine, and application thereof. Bentazone, clopyralid and atrazine are used as main active components of the weeding composition, and the mass ratio of bentazone to clopyralid to atrazine is 1-70:1-60:1-60. The weeding composition provided in the invention has substantial effects in application of weeding after seedling emergence in a cornfield, especially in application of preventing and eliminating grassy and broadleaf weeds in the cornfield. Compared to a single weedicide, on the premise of improving drugeffects, the weeding composition in the invention enables resistance of weeds to be delayed, has a broad weeding spectrum and a long persistent period, and is safe to maize and 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 three-component compound herbicidal composition of bentazone, clopyralid and atrazine. The herbicidal composition can be used for post-emergence weeding in corn fields. Background technique [0002] Bentazone is also known as Paicaodan and Bendazone. Chemical name: 3-isopropyl-(1H)-benzo-2,1,3-thiadiazin-4-one-2,2-dioxide, the structural formula is: [0003] [0004] This herbicide is a contact-type selective post-emergence herbicide, used for stem and leaf treatment at the seedling stage, and works through leaf contact. When used in dry fields, it first penetrates through the leaf surface and is transmitted to the chloroplast to inhibit photosynthesis. When used in paddy fields, it can penetrate through the leaves and absorb through the roots, and is transmitted to the stems and leaves, which strongly hinders the photosyn...
