Abstract

The invention belongs to the field of herbicides and discloses a mixed herbicide containing bentazone, acifluorfen and clethodim and an application thereof. The herbicide uses bentazone, acifluorfen and clethodim as main active ingredients, and the mass ratio of bentazone, acifluorfen and clethodim 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 for 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 bentazone, acifluorfen and clethodim 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 ingredients ...
