Abstract

The invention discloses a herbicidal composition containing bentazone and cyhalofop-ethyl. The herbicidal composition uses bentazone and cyhalofop-ethyl as main active ingredients, and the mass ratio of bentazone and cyhalofop-ethyl is 1~80:1~80. The herbicidal composition of the present invention is applied to post-emergence weeding in paddy fields, especially for controlling gramineous and broad-leaved weeds in paddy 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 to rice and subsequent crops under the premise of improving the efficacy of a single agent.

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 binary compound herbicidal composition of bentazone and cyhalofop-methyl. The herbicidal composition can be used for post-emergence weeding in paddy 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 physiologica...
