At present, the most commonly used glufosinate-ammonium is the racemate of L-type and D-type glufosinate-ammonium (ie a mixture of L-type and D-type each accounting for 50%), of which L- glufosinate-ammonium has herbicidal effect, while D-type almost Inactive. L-Glufosinate-ammonium, also known as refined glufosinate-p, was originally discovered as the active metabolite of the biological pesticide herbicide bialaphos in plants. Its herbicidal activity is twice that of ordinary glufosinate-ammonium, and the application rate per mu is only glufosinate-ammonium. 50% of phosphine, the application cost of the two is basically the same. The development and production of Glufosinate-p will greatly reduce the dosage of the original drug, which plays a very important role in improving product economy, reducing the use of pesticides, and reducing environmental pressure
Compound objects of refined glufosinate-p:
(1) The combination of glufosinate-p and dicamba has good synergy and synergistic effects. It can be effectively used for the control of perennial tolerant plants, older weeds, etc., and effectively improve the control range of glufosinate-p and dicamba. Significantly extend the validity period.
(2) A combination of glufosinate-p and diphenyl ether herbicides can be used to control grass weeds, broadleaf weeds and sedge weeds. Through the compounding of multiple active ingredients, the effect is fast, the herbicidal spectrum is expanded, and the environmental compatibility is improved.
(3) The compound of glufosinate-p and saflufenacil can be used to control grass weeds, broadleaf weeds and sedge weeds. Through the compounding of a variety of active ingredients, the low-temperature efficacy is improved, thereby improving the control efficiency, expanding the herbicidal spectrum, and reducing the dosage of the drug.
(4) One or more combination of glufosinate-p and sulfonylurea herbicides can be used to control grass weeds, broad-leaved weeds and sedge weeds. The combination of multiple active ingredients can expand the herbicidal spectrum, reduce or eliminate high temperature phytotoxicity, and reduce sensitivity to rainy weather.
(5) The compound of glufosinate-p and 2-methyl-4 chloride can be used to control perennial grass weeds, broad-leaved weeds and sedge weeds. Through the compounding of multiple active ingredients, it can improve the low-temperature control effect and the control efficiency of perennial weeds, increase the speed of weed control, expand the weed control spectrum, and reduce the dosage of the medicine.
(6) The compound of glufosinate-p and glyphosate can be used to control perennial grass weeds, broad-leaved weeds and sedge weeds. Through the compounding of a variety of active ingredients, the control efficiency of perennial weeds is improved, the quick-acting effect of the medicament is improved, the herbicidal spectrum is expanded, and the dosage of the medicine is reduced.
(7) One or more compound of one or more pyridine ester herbicides in the pyridine ester herbicides can be used to control grass weeds, broad-leaved weeds and sedge weeds. Through the compounding of multiple active ingredients, the effect is fast, the herbicidal spectrum is expanded, and the environmental compatibility is improved.
(8) The compound of glufosinate-p and clethodim can be used to control perennial grass weeds, broad-leaved weeds and sedge weeds. Through the compounding of multiple active ingredients, the control efficiency of older weeds is improved, the control effect of low temperature is improved, the dosage of active ingredients for weed control is reduced, the quick-acting effect of the medicine is improved, and the dosage of the medicine is reduced.
(9) The compound of glufosinate-p and pyridine acid herbicides can be used to control grass weeds, broad-leaved weeds and sedge weeds. Through the compounding of multiple active ingredients, the dosage of medicament is reduced, thereby reducing drug residues and improving environmental compatibility.
(10) The compound of glufosinate-p and quizalofop-p-ethyl can be used to control perennial grass weeds, broad-leaved weeds and sedge weeds. Through the compounding of multiple active ingredients, the control efficiency of older weeds is improved, the control effect of low temperature is improved, the dosage of active ingredients for weed control is reduced, the quick-acting effect of the medicine is improved, and the dosage of the medicine is reduced.
(11) A combination of glufosinate-p, penoxsulam and oxfentrazone, can be used to control grass weeds, broad-leaved weeds and sedge weeds. The combination of multiple active ingredients can increase the rate of weeding and reduce drug residues.
