Background technology
Glyphosate (glyphosate), has another name called glyphosate, and agriculture reaches (Roundup), the sweet acid of phosphine etc., and its chemical name is: N-(phosphoryl methyl) glycine.Glyphosate is current most economical interior suction conduction nonselective herbicide in the world, mainly absorb by cauline leaf, conduct under ground portion, suppress enol acetonyl shikimene phosphonic acids synzyme in plant corpus, thereby in inhibition plant corpus, shikimene transforms to phenyl alanine, tyrosine and tryptophan, protein is synthesized and be interfered, cause weeds death.
Glyphosate is a kind of organophosphorus herbicide of being developed at first by About Monsanto Chemicals for 1971.Since 20 century 70 commercializations in mid-term, due to the characteristic of the good herbicidal performance of glyphosate and low-residual, range of application constantly expands, and output increases rapidly, is the important kind in weed killer herbicide.In China, glyphosate also becomes one of kind of output maximum in weed killer herbicide.Mainly by add the method for surfactant in liquid, further improve its activity at present, reduce use cost, also have the report with some chemical fertilizer composite usage synergy.
Glyphosate is the main medicament of preventing and kill off perennial weed both at home and abroad.Glyphosate has broad weed-killing spectrum, holds concurrently except the remarkable advantage of therophytes and perennial root plant, can prevent and kill off unifacial leaf and plant dicotyledonous, annual and the section more than 40 such as perennial herb and shrub.After glyphosate buries, be combined and lose activity with the metal ion such as iron, aluminium very soon, seed hiding in soil and edaphon are had no adverse effects.This medicament is very low to aquatile toxicity, is that the water environment of the country such as the U.S., Australia allows one of minority weed killer herbicide kind using.
In existing glyphosate products, glyphosate is mainly with isopropylamine (IPA) salt, dimethylamine (DEA) salt, ammonium (NH
4) salt, potassium (K) salt, sodium (Na) salt, the salt of these five kinds of forms has been listed " (glyphosate and its esters registration management suggestion (exposure draft) " that the Institute for the Control of Agrochemicals of the Ministry of Agriculture,PRC issued on October 8th, 2013 in.In these products, under the identical weed killer herbicide concentration in glyphosate, isopropyl amine salt effect is best.
Zeneca Ltd. is in the patent 03809541.6 (application number) of China application, mentions trimethylsulfonium (Trimesium), the MEA (MEA) of glyphosate in the time doing brewed dose of low one-tenth.Akzo Nobel limited company patent 200980132051.7 (application number) is mentioned diethanol amine (DEA), the triethanolamine (TEA) of glyphosate in the time doing thickening glyphosate formulation.In existing technical literature, all do not mention the composition that uses glyphosate and multi-element organic amine salify.
In test, we find, containing multi-element organic amine, particularly contain the salt forming agent of ethylene diamin(e), the in the situation that of glyphosate same amount, can use less salt forming agent, and the glyphosate salt of selecting suitable organic polyamine to make as salt forming agent can significantly improve the herbicidal effect of glyphosate formulation, be better than existing glyphosate salt forming agent (as isopropylamine, sodium hydroxide, potassium hydroxide, ammoniacal liquor, dimethylamine etc., in existing technical scheme, the effect of isopropylamine is best).Use the consumption of organic polyamine salt forming agent to be less than isopropylamine, new composite formula cost is significantly lower than the cost that uses glyphosate isopropyl amine salt.
For reaching identical result of use, while using glyphosate organic polyamine salt, the consumption of surfactant can be less than the consumption of surfactant in the known glyphosate formulations such as glyphosate isopropyl amine salt, also can reduce costs, and reduces the pollution bringing to spraying chemical substance in environment.
