Abstract

The invention discloses a glyphosate and glufosinate ammonium compounded herbicide composition. The glyphosate and glufosinate ammonium compounded herbicide composition is prepared from glyphosate, glufosinate ammonium, levo-alpha-terpilenol and a traditional Chinese medicine additive; the traditional Chinese medicine additive comprises callistemon rigidus, erodium stephanianum willd, geranium, artemisia annua, cape marigold, Chinese pulsatilla root, coptis chinensis, xanThium sibiricum, sophora alopecuroide, rheum officinale, garlic, folium artemisiae argyi, honeysuckle and houttuynia cordata; the composition can further be matched with an agriculturally pharmaceutically acceptable carrier to prepare preparations like a missible oil, a microemulsion, an emulsion oil in water, a suspendingagent, a wettable powder, a water dispersible granule, a suspoemulsion, a granule, an aqueous solution and a powder, and the composition is convenient to use and store. The glyphosate and glufosinateammonium compounded herbicide composition has an obvious synergistic interaction, is low in toxicity, high in efficiency, and long in lasting period, and is organic and environmentally friendly, theuse amount of a herbicide is reduced, the use cost and the environment pollution are reduced, and the grassy weeds, the sedge weeds and the broadleaf weeds in the forest land and the non-cultivated land are effectively prevented and killed.

Description

technical field [0001] The invention relates to herbicides in the field of agriculture, more specifically to a compound herbicide composition of glyphosate and glufosinate-ammonium. Background technique [0002] At present, the herbicides used on forest land are mainly herbicides such as glyphosate and Kewuzong. However, glyphosate alone has little effect on some weeds, and the effect on broad-leaved weeds is not ideal; Ke Wuzong is a contact herbicide, which can only kill the above-ground parts of plants, and has no effect on some perennial weeds. Poor, and its own high toxicity, easy to cause poisoning incidents. [0003] Glyphosate is a systemic broad-spectrum herbicide. Safer for natural enemies and beneficial organisms. It mainly inhibits the enolpyruvyl shikimelin phosphate synthase in plants, thereby inhibiting the conversion of shikimelin to phenylalanine, tyrosine and tryptophan, interfering with protein synthesis and causing plant death. Glyphosate is known for...
