Abstract

A high-safety additive of herbicide for improving its effect and decreasing its toxic by-effect is prepared from diethylamino ethanol caproate (0.5-95 Wt%) and potassium dihydrogen phosphate (5-99.5 Wt%).

Description

A kind of herbicide safety additive

Technical field

The present invention relates to a kind of herbicide safety additive.

Background technology

China is that an Agricultural Bio-disasters takes place frequently, one of large agricultural country of agroecological environment fragility, China region is wide, weather conditions are different, and farmland weed is of a great variety, and the important weeds that agricultural production is worked the mischief have kind more than 50, cause the malignant weed of serious harm that kind more than 20 is arranged, China farmland is subjected to the weeds hazard area to be about 6,000 ten thousand hectares every year, 3,000 ten thousand hectares of serious injured areas, and direct economic loss is up to more than 200 hundred million RMB.In January, 26.4%, 2005 China's weed killer herbicide output that present weed killer herbicide output in China's registration accounts for the pesticide producing total amount increases by 46.4% on a year-on-year basis.Along with constantly applying of modern agriculture High-Tech result, present national farmland chemical herbicide popularizing area has reached 1,000,000,000 mu times, and modern agriculture is more and more stronger to the dependence of weed killer herbicide.Yet the effect of chemical herbicide in agricultural production is more and more important.In China, the history of existing more than ten years of the application of chemical herbicide, and consumption is increasing, atrazine plus acetochlar is increased to 200ml/ mu from originally 100ml/ mu, now breaks through 250ml/ mu; Tribenuron-methyl is increased to present 2g/ mu from 0.75g/ mu originally; Trefanocide is increased to present 150ml/ mu from 100ml/ mu originally, have in addition surpass 200ml/ mu; Particularly long-acting high residue weed killer herbicides such as the clomazone that uses in the northern China grain-producing area, Sulfometuron Methyl have been increased to more than two or three times; When improving herbicidal effect, because the variety of issue of a large amount of residual initiations of weed killer herbicide becomes increasingly conspicuous.Because the application of agricultural chemicals such as chemical herbicide, chemical pesticide is residual and pollute the life that has promptly endangered the people, has brought serious disaster to agricultural production again.The harm of weed killer herbicide on agricultural generally has following several: (1) recessive poisoning, poisoning directly perceived; (2) hide poisoning, the outburst poisoning.Recessive poisoning mainly occurs in crop such as wheat when the seedling spraying weed killer herbicide, selected the homemade outstanding weed killer herbicide of import, though these weed killer herbicides can not cause poisoning directly perceived, but can have influence on the reproductive growth of crops such as wheat, make crop roots such as wheat undeveloped, minimizing is tillered, and resistance against diseases is poor, the incidence of disease is high especially, generally makes more than the crop failure 7-20%.Selected import or homemade part weed killer herbicide inferior when intuitively the poisoning first is owing to the spray medicine for use, made crops suffer the serious underproduction or total crop failure; It two is that blindly medication frequently occurs, can not be in strict accordance with period that requires and dosage medication because the level of peasant's medication is low; In addition, poisoning is to use residual the exceeding standard of chemical herbicide accumulative total year after year owing to hide, the outburst poisoning takes place in about more than 6,000 ten thousand mu of soils, Heilongjiang Province, area, China northeast in this year, weed killer herbicide is promoted relatively early in area, China northeast, chemical residual exceeds standard in the soil, and variation symptoms such as fertilizer are not lacked of proper care, dewatered, take off to length, stiff seedling, Huang Ye, dried point, photosynthesis to cause soybean, rice seedling dead seedling, mashed root, atrophy to occur.Investigate according to Ministry of Agriculture's agricultural chemicals evaluation, weed killer herbicide accounts for 80% in the various pesticide injuries of China, and herbicide residue and poisoning are very severe at present, and existing plant growth promoter can only use separately, and can not with herbicide mixture, this has brought very big trouble for peasant household in the use.

Summary of the invention

The object of the present invention is to provide a kind of herbicide safety additive,, produce thereby make crops avoid being subjected to poisoning and reduce poisoning to quicken the degradation speed of weed killer herbicide in the farming object.

To achieve these goals, technical program of the present invention lies in having adopted a kind of herbicide safety additive, comprise that weight percentage is that diethylamino ethanol caproate and the weight percentage of 0.5-95% is the potassium dihydrogen phosphate of 5-99.5%.

Described potassium dihydrogen phosphate can use any one or its any combination in urea, fulvic acid or the turpentine oil to substitute.

Diethylamino ethanol caproate and potassium dihydrogen phosphate among the present invention are used with, can improve plant body inner chlorophyll, protein, the content of nucleic acid and photosynthetic rate, improve the activity of peroxidase and nitrate reductase, promote carbon, the nitrogen metabolism of plant, strengthen plant to the absorption of liquid manure and the accumulation of dry matter, water balance in the control agent, strengthen crop, fruit tree disease-resistant, drought resisting, cold tolerance; Delay plant senesecence, promote the quality of crop precocity, volume increase, raising crop, reach volume increase, increase matter.In addition, can also play a protective role, make poisoning recover to speed, replenish the phosphorus in the crops various crops; Herbicide safety additive of the present invention and herbicide mixture do not have the opposite effect.Two kinds of components matching of the present invention are used, and action effect was fast, than the fast 5-10 of existing plant growth promoter days.Safe additive of the present invention can be used for various effects, can avoid the generation of poisoning and reduction poisoning, and the present invention experiment showed, that through large tracts of land result of use is fine, and effect of increasing production is obvious; In addition, production cost of the present invention is low, is easy to apply.

Safe additive of the present invention is compared with other medicament, and the result is as follows:

Experimental result shows: the present invention and weed killer herbicide share and can effectively solve the recessive poisoning that causes to crops because of herbicide residue, prevent efficient more than 85.7%, significant difference.Can improve simultaneously the availability of weeding speed and weed killer herbicide, can prevent the multiple diseases that causes because of herbicide residue effectively, protect productive rate, have good economic worth and social value, be easy to apply up to 46%.

When the present invention was pulvis, promptly diethylamino ethanol caproate and potassium dihydrogen phosphate were mixed with, and 0.07 hectare uses one bag, and one bag heavy 40 gram is converted water 20-30 kilogram for one bag.

When the present invention was liquor, promptly any one or its any combined hybrid in diethylamino ethanol caproate and urea, fulvic acid or the turpentine oil prepared, and every bag 200 gram is converted water 200-300 kilogram for one bag, every bag of half hectare of ground.
