Problems solved by technology

However, acifluorfen is ineffective against grass weeds and sedges, and soybeans have contact damage. Therefore, the dosage should be strictly controlled during use, or mixed with other herbicides to reduce phytotoxicity and improve grass resistance. The Control Efficacy of Undergraduate Weeds
[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 belongs to the field of herbicides and discloses a mixed herbicide containing bentazone, acifluorfen and sethenoxydim and an application thereof. The herbicide uses bentazone, acifluorfen and sethoxydim as main active ingredients, and the mass ratio of bentazone, acifluorfen and sethoxydim is 0.1~80:0.1~80:0.1~80 , the total mass percentage of the three in the herbicide is 1-85%. The application of the mixed herbicide of the present invention in post-emergence weeding in soybean fields, especially in the application of controlling various gramineous or broad-leaved weeds in soybean fields has remarkable effects. Compared with a single dose, the herbicide of the present invention delays weed resistance, has a wide herbicide spectrum, long duration of action and is safe to soybeans and subsequent crops under the premise of improving the efficacy of a single agent.

Description

Technical field [0001] The invention belongs to the field of herbicides, and relates to a mixed herbicide containing triflufen, acifluorfen and enoxypyr and its application. technical background [0002] Bentasone, also known as Paicaodan and Bentasone. Chemical name: 3-isopropyl-(1H)-benzo-2,1,3-thiadiazine-4-one-2,2-dioxide, the structural formula is: [0003] [0004] The herbicide is a contact-killing selective post-emergence herbicide, used for the treatment of stems and leaves at the seedling stage, and works through leaf contact. For dry field use, the leaf surface penetrates and conducts to the chloroplast to inhibit photosynthesis. The use of paddy field can not only penetrate through the leaf surface but also be absorbed through the roots, and be transmitted to the stems and leaves, which strongly hinder the photosynthesis and water metabolism of weeds, cause nutrient starvation, and cause death due to physiological disorders. The active ingredients are metabolized to ...
