Current chemical weed control has become the important measures of weed control in agricultural production, also improves agricultural production efficiency, especially the application of amino acids herbicide glyphosate, glufosinate-ammonium, changes the general layout of agricultural weeding. But in actual use, chemical weed control needs substantial amounts of water as scattered carrier, and peasant has to the diluent bearing tens kilograms in farm work, considerably increases the labor intensity of peasant, being greatly reduced labor efficiency, this seems more prominent in the area of water intaking and operation difficulty simultaneously. Simultaneously when using conventional herbicide products to carry out spraying operation, herbicide drift phenomenon is serious, the dangerous to the crop generation poisoning of periphery; On the other hand conventional herbicide products resistance of rainwater washing against performance is poor, it is necessary to after dispenser at least 6H without rain.
In order to solve the problems referred to above, the use technology of herbicide is conducted in-depth research by countries in the world, for reducing labor intensity, reducing drift and aspect of raising labour efficiency proposes different solutions. Wherein in the U.S., people are in order to solve in the spraying application of pesticide diluent, and medicinal liquid drips the problem with wind drift, it is common to use water-soluble polymer such as guar gum as drift control agents with control drift. In Japan, peasant is for preventing drift, it is desirable to medicinal liquid viscosity is at least tens of centipoise, village this etc. develop in medicinal liquid, add high-grade water solubleness gel (consumption is the 0.025%��3% of the herbicide diluent weight) method that prevents medicinal liquid drift. Zhu shawn is disclosed at Chinese patent CN102123594A, said preparation makes glyphosate formulation thickening by adding nitrogen-containing surfactants, the problem that this patent solves is to meet the market demand, a kind of dense thick glyphosate formulation is provided, is not solve that current glyphosate formulation sprinkling process exists the problem that drift phenomenon causes risk.
Therefore, the above-mentioned various defects existing for low-gallonage spraying are carried out in the urgent need to a kind of amino acids water baseization herbicide suitable in low-gallonage spraying to solve current existing amino acids herbicide.
Summary of the invention:
For drawbacks described above, it is an object of the invention to provide a kind of amino acids water baseization herbicide for low-gallonage spraying, herbicide can be realized and carry out low-gallonage spraying, improve preventive effect and the work efficiency of weeding, reduce labor intensity and reduce the poisoning risk that when spraying, drift brings.

In the operating process of common agricultural, agriculture labourer and professional of agriculture are when carrying out weeding operation, the mode of the large aperture sprinkler of high-volume spraying and medium volume spraying is usually taken, and performance of keeping humidity and the anti-drift performance of medicinal liquid are paid close attention to and require less by this. But it is as the development of plant protection apparatus and the continuous lifting of value of labour power, low-gallonage spraying (every mu of amount of liquid medicine is at the 0.4kg-1kg) mode of low-gallonage spraying (every mu of amount of liquid medicine is at 1kg-10kg)/develops increasingly very much, it has also become the developing direction that plant protection field is new. But when using common medicament to carry out the low-gallonage spraying of low-gallonage spraying/very, droplet tails off, it is easy to cause drift; On the other hand spraying droplet is just arriving after target quickly evaporation drying, makes pesticide active ingredient be difficult to be absorbed by target and conduct, and drug effect is difficult to ensure that. Wetting agent and drift control agents are effectively combined by the present invention, increasing on the basis of droplet median diameter, significantly improve the spraying droplet wetting time at target surface, be conducive to target fully absorbing and conducting farm chemical ingredients, while reducing drift risk, drug effect is had the effect of being obviously improved, be effectively guaranteed safety and the effectiveness of the low-gallonage spraying of low capacity/very; In drug effect performance, owing to invention formulation amount of being watered when spraying is little, greatly reduce the impurities in water influence to medicament effective ingredient, simultaneously because spouting liquid is little in unit are, significantly reduce the medicinal liquid loss in crop surface, add the effective ingredient enrichment in crop surface, simultaneously because effective ingredient and auxiliary agent content are significantly high in unit volume, accelerate the conduction in the infiltration and plant of plant leaf blade of the herbicide effective ingredient, be conducive to the performance of drug effect; In dispenser efficiency, owing in unit are, water consumption substantially reduces, every mu of spouting liquid is 1 liter-10 liters, relative to conventional spray, every mu of working performance improves 3 times, and this will greatly reduce the work load of dispenser workman, raise labour efficiency, be substantially reduced the cost in agricultural operation.
As preferably, herbicide active active ingredients 20%-41%, surfactant 5%-10%, synergist 5%-12%, wetting agent 1%-10%, drift control agents 0.1%-0.5%, defoamer 0.05%-0.08%, remainder water.
By to for the screening of the compatibility of each component, content ratio in the amino acids water baseization Herbicidal composition of low-gallonage spraying, the formula that we prefer that out is more prominent in effect, especially the performance reducing drift and moisturizing aspect is significantly improved.
In the present invention, amino acids herbicidal active component is one or more the combination in glufosinate-ammonium, glufosinate-ammonium-P sodium salt, glyphosate, ammonium glyphosate, glyphosate dimethylamine salt, glyphosate potassium, glyphosate isopropyl amine salt.
