Problems solved by technology

And the application period is longer
However, the herbicidal spectrum is narrow, and it is ineffective against broad-leaved weeds and perennial root weeds. The herbicidal spectrum is single, and the control of weeds is limited.
[0008] At present, herbicides in paddy fields are limited by the safety of crops, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in paddy fields. Too long effective period, 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 milinadin and its application. The herbicidal composition uses bentazone and milinadin as main active ingredients, wherein the mass of bentazone and milinadin The ratio is 1-80:1-80, and the herbicidal composition of the present invention can be applied to weeding after emergence in paddy fields, especially in the control of gramineous and broad-leaved weeds in paddy fields with remarkable effects. Compared with a single dose, 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 specifically relates to a binary compound herbicidal composition of bentazone and molinate, which can be applied to 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 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 metabolism ...
