Abstract

The invention discloses a herbicidal composition containing sethoxydim and bentazone. The herbicidal composition uses sethoxydim and bentazone as main active ingredients, and the mass ratio of sethoxydim to bentazone is 1-80. : 1-80. The herbicidal composition of the invention is applied to post-emergence weeding in soybean fields, especially for controlling various gramineous and broad-leaved weeds in soybean fields, and has remarkable effects. Compared with a single agent, the herbicidal composition of the present invention delays weed resistance, has a wide herbicidal spectrum, long duration of action, and is safe for soybeans and subsequent crops under the premise of improving drug efficacy.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and specifically relates to a binary compound herbicidal composition of bentazone and sethenoxydim, which can be applied to post-emergence weeding in soybean 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 physiological dysfunction and death...
