Abstract

The invention belongs to the field of pesticides, and in particular relates to a herbicidal composition containing triazole sulcotrione and pyridazine compounds and an application thereof. The herbicidal composition comprises active ingredient A and active ingredient B in herbicidally effective doses, wherein active ingredient A is triazosulfotrione, and B is a pyridazine compound selected from pyridazine or cyclopyrimorate. The composition can effectively control weeds such as Solanum nigrum, Stephania japonica, barnyard barnyardgrass and barnyardgrass in paddy fields, has the advantages of expanding the herbicidal spectrum, reducing the amount of application, being safe for crops, and capable of producing synergistic effects and solving resistant weeds Features.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a herbicidal composition containing sulfentrazone and pyridazine compounds and application thereof. Background technique [0002] Chemical weeding is the most economical and effective method for weed control in farmland. However, the long-term continuous and high-dose use of chemical herbicides of a single species or single mode of action is likely to cause problems such as weed resistance and resistance evolution. [0003] The chemical structural formula of sulfentrazone is It is a newly developed HPPD inhibitor herbicide for post-emergence stem and leaf treatment in paddy fields. It has excellent biological activity and can effectively control various malignant weeds in paddy fields. [0004] The chemical structural formula of dazat is It is a selective post-emergence herbicide. The stems and leaves are quickly absorbed by the leaves after treatment, hindering the Hil...
