Problems solved by technology

However, it is basically ineffective against Clover, Echinacea, and wild water chestnuts. The weeding 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 weeding composition containing bentazone and propanil and application thereof. The weeding composition comprises the following main effective components: the bentazone and the propanil, wherein the mass ratio of the bentazone to the propanil is (0.1-80):(0.1-80). The weeding composition disclosed by the invention can be applied to the post-emergence weeding for paddy fields and especially has an outstanding effect on preventing and weeding gramineous weeds and broadleaf weeds in the paddy fields; in addition, compared with a single agent, the weeding composition disclosed by the invention has the advantages of weed resistance delay performance, broad weeding spectrum, and long acting period under the precondition of enhancing a weeding effect and has safety for paddy rice and succession crops.

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 containing bentazone and propannil, 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 me...
