Problems solved by technology

[0008] At present, herbicides in soybean fields are limited by the safety of crops, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely effectively control the occurrence of weeds in soybean fields. Too long, excessive dosage or uneven application will easily cause residual toxicity to current crops or subsequent crops

Abstract

The invention discloses a herbicidal composition containing bentazone and fenoxaprop-p-ethyl. The herbicidal composition uses bentazone and fenoxaprop-p- The mass ratio of grass spirit is 1-60:1-60. The herbicidal composition of the invention can be used for post-emergence weeding in soybean fields, especially for controlling 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, especially the field of herbicides, and specifically relates to a binary compound herbicidal composition of bentazone and fenoxaprop-ethyl, 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 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. 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 metabol...
