Abstract

The invention belongs to the field of herbicide, and discloses a mixed herbicide containing bentazone, acifluorfen and molinate, and application thereof. The herbicide comprises main effective components of bentazone, acifluorfen and molinate in a mass ratio of 0.1-80:0.1-80:0.1-80. The mixed herbicide of the invention has substantial effects on application to weeding after seedling in a rice field, especially application to control of gramineae weeds and broad leaf weeds in the rice field. Compared with a single dose, the herbicide of the invention, on the premise of enhancing drug effect, delays weed resistance, has a wide weeding spectrum and a long persistent period, and is safe to rice and later crops.

Description

technical field [0001] The invention belongs to the field of herbicides, and relates to a mixed herbicide containing bentazone, acifluorfen and molinate 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 o...
