The N-(phosphonomethyl)glycine (Glyphosate) salt which is the N-(phosphonomethylglycine) 1H-1,2,4-triazol-3-ylamine salt (Glyphosate triazolamine salt). Preferably, it is the N-(phosphonomethylglycine) mono-1H-1,2,4-triazol-3-ylamine salt (Glyphosate mono-triazolamine salt) of formula:
Useful concentrate composition for the “in situ” preparation of a phytotoxic formulation by dilution with water, or by dissolution in water to reach a required active compound concentration, which is a liquid or solid product wherein the active compound comprises the Glyphosate triazolamine salt, and at least an auxiliary including agriculturally acceptable diluents, extensors, carriers, conditioning agents, humidifying agents, and/or dispersing or emulsifying agents; and such phytotoxic formulation. A process to prepare a liquid concentrate composition of the Glyphosate triazolamine salt comprising: (a) suspending acid glyphosate in water; and (b) slowly adding triazolamine under constant stirring, and keeping the temperature from 15 to 40° C., and additionally adding an agriculturally acceptable auxiliary; and a process to prepare a solid concentrate composition of the Glyphosate triazolamine salt comprising the mixture of acid glyphosate and triazolamine, and the additional addition of an agriculturally acceptable auxiliary. A method to combat weeds in a crop by the application of the phytotoxic formulation on the existing weeds in a crop, or a plantation of fruit trees, to control weeds, preferably Aleppo grass (
Sorghum halepense
), Bermuda grass (
Cynodon dactylon,
water grass (
Echinochloa crusgalli
), summer grass (
Digitaria sanguinalis
), sunchillo (
Wedelia glauca
), nutgrass (
Cyperus rotundus
), blite (
Amaranthus quitensis
), wild buckwheat (
Polygonum convolvulus
), and pigweed (
Chenopodium album
).
N-(磷酸甲基)甘氨酸(草甘膦)盐,即N-(磷酸甲基)甘氨酸1H-1,2,4-三唑基胺盐(草甘膦三唑胺盐)。最好是N-(磷酸甲基)甘氨酸单一H-1,2,4-三唑基胺盐(草甘膦单三唑胺盐)的配方:
有用的浓缩组合物,通过与水稀释或在水中溶解以达到所需的活性化合物浓度,该活性化合物包括草甘膦三唑胺盐,以及至少一种辅助剂,包括农业可接受的稀释剂,扩展剂,载体,调理剂,湿润剂和/或分散或乳化剂;以及这种植物毒性配方。
制备草甘膦三唑胺盐的液体浓缩组合物的过程包括:(a)将酸性草甘膦悬浮在水中;(b)缓慢加入三唑胺,同时不断搅拌,并保持温度在15至40°C之间,并额外添加农业可接受的辅助剂;以及制备草甘膦三唑胺盐的固体浓缩组合物的过程,包括酸性草甘膦和三唑胺的混合物,并额外添加农业可接受的辅助剂。
通过在作物中将植物毒性配方施用于现有的杂草或果树种植园,以控制杂草,最好是阿勒颇草(Sorghum halepense),百慕大草(Cynodon dactylon),水草(Echinochloa crusgalli),夏草(Digitaria sanguinalis),sunchillo(Wedelia glauca),莎草(Cyperus rotundus),blite(Amaranthus quitensis),野荞麦(Polygonum convolvulus)和藜(Chenopodium album)的方法来对抗作物中的杂草。
