Abstract

The invention discloses a weeding compound containing bentazone, dicamba and atrazine. Bentazone, dicamba and atrazine are taken as the main active principles of the weeding compound and the mass ratio of bentazone to dicamba to atrazine is (1-70):(1-70):(1-70). The weeding compound is applied to weeding after seedling in a corn field and has especially obvious effect for removing gramineae weedsand broad leaf weeds from the corn field. Compared with a single agent, the weeding compound provided by the invention has the advantages that the pesticide effect is promoted, the weeds resistance is restrained, the weeding scope is wide, the effect is long-lasting and the weeding compound is safe to corn and post-cultured crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and in particular relates to a ternary compound herbicidal composition of bentazone, dicamba and atrazine. The herbicidal composition can be applied to post-emergence weeding in corn fields. Background technique [0002] Mechasong, also known as Paicaodan and Bendasone. Chemical name: 3-isopropyl-(1H)-benzo-2,1,3-thiadiazin-4-one-2,2-dioxide, the herbicide is a contact type selective post-emergence Herbicides, used in seedling stem and leaf treatments, act by leaf contact. When used in dry fields, it first penetrates into the chloroplast through the leaf surface to inhibit photosynthesis. The use of paddy fields can not only penetrate through the leaves but also 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 physiolog...
