Embodiment 1

[0044] Experimental report on the activity of the mixture of glufosinate-ammonium and dicamba on weeds

[0045] Purpose of the test: To determine the herbicidal effect of the mixture of glufosinate-ammonium and dicamba on target weeds under potted conditions in the greenhouse, and to evaluate their combined effect.

[0046] Test target: grass weed - goosegrass

[0047] Test method: potted stem and leaf treatment (NY / T1155.4-2006): set soil in a flower pot with a height of 10 cm and a diameter of 10 cm, sow 15-20 weed seeds of the target weed, cover with a thickness of 0.5-1 cm After the weeds grow to the 2-4 leaf stage, the stems and leaves are sprayed with 12mL per spray, repeated 4 times, and a blank control is set up. After treatment, place them in the greenhouse for cultivation, regularly observe the growth of the target weeds, measure the symptoms and inhibition of the target for 15 days, and weigh the fresh weight of the aboveground part or the fresh weight of the plant...

Abstract

The invention relates to a refined glufosinate ammonium-dicamba compound, which consists of an active component accounting for 20 to 70 percent of the total weight of the refined glufosinate ammonium-dicamba compound and auxiliary material accounting for 30 to 80 percent of the total weight of the refined glufosinate ammonium-dicamba compound; the active component is a mixture of refined glufosinate ammonium and dicamba at a weight ratio of 0.01 to 100:1. All the components of the refined glufosinate ammonium-dicamba compound have a good synergetic effect, and the refined glufosinate ammonium-dicamba compound can be effectively used for preventing and controlling perennial tolerant plants, elder weeds and the like, effectively broaden the prevention and control range of the refined glufosinate ammonium and the dicamba and remarkably prolong persistence. Moreover, the preparation method of the refined glufosinate ammonium-dicamba compound is simple and easy to implement, processing equipment is easy to obtain, the cost is low, and the refined glufosinate ammonium-dicamba compound has obvious market promotion value and economic benefit.

Description

technical field [0001] The invention belongs to the application field of agricultural chemicals, and in particular relates to a compound composition of refined glufosinate-ammonium and dicamba. Background technique [0002] The chemical formula of glufosinate ammonium is C 5 h 12 NO 4 P, the formula weight is 181.27, the chemical name is 4-[hydroxyl (methyl)phosphono]-L-homoalanine, it is L-type glufosinate-ammonium, it is easily soluble in water, not easily soluble in organic solvents, and is suitable for light Stable, melting point 214-216 ℃, is a highly efficient, low toxicity, non-selective contact type phosphoric acid herbicide. The refined glufosinate-ammonium is an L-type glufosinate-ammonium, and its herbicidal activity is twice that of the racemic DL-type glufosinate-ammonium mixture. Glufosinate-ammonium inhibits glutamine synthetase, leading to nitrogen metabolism disorder in plants, accumulated ammonia poisoning, and then chloroplast synthesis, photosynthesis...
