Problems solved by technology

[0011] At present, herbicides in paddy fields are limited by the safety of crops, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in paddy fields. 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 mixed herbicide containing bentazone, cyhalofop-butyl and quinclorac, and application thereof, belonging to the field of herbicides. Bentazone, cyhalofop-butyl and quinclorac are used as main active components of the mixed herbicide, the mass ratio of bentazone to cyhalofop-butyl to quinclorac is 0.1-80:0.1-80:0.1-80, and the total mass percentage of the three componentsin the mixed herbicide is 1 to 85%. The mixed herbicide provided in the invention has substantial effects in application of weeding after seedling emergence in a paddy rice field, especially in application of preventing and eliminating various grassy and broadleaf weeds in the paddy rice field. Compared to a single herbicide, on the premise of improving drug effects, the mixed herbicide in the invention enables resistance of weeds to be delayed, has a broad weeding spectrum and a long persistent period, and is safe to paddy rice and succeeding crops.

Description

technical field [0001] The invention belongs to the field of herbicides, and relates to a mixed herbicide containing bentazone, cyhalofop-ethyl and quinclorac and an application thereof. technical background [0002] Benazone, also known as paicaodan, bentazon, chemical name: 3-isopropyl-(1H)-benzo-2,1,3-thiadiazin-4-one-2,2-dioxide thing, 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. When used in paddy fields, it can penetrate through the leaves and 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 physiological dysfunction and death. The active ingredi...
