Synergistic herbicide composition containing triclopyr and hexazinone and application thereof

A herbicidal composition and a technology of cycloazinone, applied in the fields of herbicides and pesticides, can solve the problem of not being able to completely and effectively control weeds and small shrubs in woodland and non-arable land, residual poisoning of current season crops or subsequent crops, and field persistence. It can improve the efficacy, delay the resistance of weeds, and widen the herbicidal spectrum.

Problems solved by technology

[0006] At present, herbicides in woodland and non-cultivated land are limited by the age of weeds, and the herbicide spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds

Abstract

The invention discloses a synergistic herbicide composition containing triclopyr and hexazinone and application thereof. In the herbicide composition, the triclopyr and the hexazinone are taken as the main active ingredients; and the mass ratio of the triclopyr to the hexazinone is 1-75: 1-75. The herbicide composition can be used for preparing herbicide for killing weeds in a woodland or non-cultivated land. Compared with single-composition herbicide, the herbicide composition has a broad herbicide spectrum and acts for a long time on the premise of improving herbicide effect, is safe for the forests and the afterculture crops, and particularly has an obvious effect of controlling various graminaccae, broadleaf weeds and undershrub in the woodland or the non-cultivated land.

Description

technical field [0001] The invention belongs to the technical field of pesticides, especially the field of herbicides, and relates to a binary compound of triclopyr and hexazinone. The herbicidal composition can be applied to forest land and non-arable land for weeding. Background technique [0002] Triclopyr (triclopyr), chemical name: 3,5,6-trichloro-2-pyridineoxyacetic acid, its chemical formula is: C 7 h 4 Cl 3 NO 3 . [0003] [0004] Triclopyr is a conductive herbicide, acting on nucleic acid metabolism, causing plants to produce excess nucleic acid, causing some tissues to transform into meristems, resulting in abnormal growth of leaves, stems and roots, depletion of storage substances, and embolization of vascular tissue Or burst, and the plant gradually dies. It can be rapidly decomposed by microorganisms in the soil. It is used to control weeds and shrubs in forest land and non-cultivated land, such as: lotus seedlings, mother-in-law, ferns, eupatorium ad...
