Problems solved by technology

However, glufosinate cannot kill small shrubs in forest land or non-cultivated land. In addition, some weeds have developed resistance to glufosinate
Its use in forest land and non-cultivated land is limited to a certain extent
[0009] 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 effectively control the occurrence of weeds and small shrubs in woodland and non-cultivated land. Due to its high water solubility or long field duration, excessive dosage or uneven application, it is easy to cause residual toxicity to current crops or subsequent crops.

Abstract

The invention discloses a synergistic herbicide composition comprising triclopyr and glufosinate and an application thereof; in the synergistic herbicide composition, triclopyr and glufosinate are used as main effective components, and the mass ratio of triclopyr to glufosinate is 1-65: 1-50. The synergistic herbicide composition can be used for preparing the herbicide for removing weeds in forest land or uncultivated area. Under the precondition that the pesticide effect is improved relative to simple dosage, the synergistic herbicide composition retards weed resistance, and has wide herbicide spectrum and long duration; moreover, the synergistic herbicide composition has safety to forest and afterreap crops, and particularly has obvious effect in all kinds of gramineous and broadleaf weeds in forest land or uncultivated area.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and relates to a binary compound of triclopyr and glufosinate-ammonium. The herbicidal composition can be applied to weeding in woodland and non-arable land. 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] The structural formula is: [0004] [0005] 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: lot...
