Abstract
The present invention relates to a coal-base acid herbicide which is formed by uniformly mixing 0.004 to 5 portions of coal-base acid and 1 portion of herbicide by weight. The problem of chemical resistance in the existing herbicide is basically solved, the manufacturing cost and using cost are greatly reduced, the coal-base acid herbicide can reduce harm toxicity to people and farm animals, and simultaneously, the coal-base acid has favorable effects of promoting the growth of crops, increasing yield, increasing harvest and improving the quality of the crops.
Description
The present invention relates to a kind of pesticide herbicide, relate in particular to a kind of coal-base acid herbicide.
Along with the chronic administration of chemical pesticide, pesticide resistance strengthens in recent years, and drug effect descends, dosing is increasing, environmental pollution and day sharp increase, particularly weed killer herbicide is the main poisonous substance source of causing the water system environmental pollution, therefore many medicaments lose using value so that be eliminated.Countries in the world solve the main path that this roughly the same inscribes at present: the one, and synthetic novel pesticide replaces old kind, but this method consumes all very surprising in time and funds, it is reported, develop a kind of novel pesticide the nineties, need screening compounds to reach more than 20,000, expensive 8,000 ten thousand dollars, visible this measure is not an optimal path; The second approach is to start with from improving existing pesticide efficacy, selects for use to make existing pesticide efficacy recover and improve the material of its drug effect, is combined into new agricultural chemicals, and this method is economically feasible but also the crisis of having avoided old farmer's medicine to be eliminated not only.Weed killer herbicide is a major types of chemical pesticide, and various weeds and crops strive fertilizer to strive water be to influence the harm greatly that the agriculture underproduction is grown and caused to the crop normal growth in agricultural production.Once mentioned in " Chinese farmland weed chemical control " (1996, Chinese agriculture publishing house publishes) book: as far back as 1950's, the Hawaii sugarcane field is just found to resist 2,4-D weeds strain system; 2,4-D uses in China's Heilungkiang large tracts of land and has reached 30 years, and its herbicidal effect is passed in time and obviously descended." agricultural chemicals " magazine, 1993 the 32nd the 2nd phases of volume: clearly propose in " the drug-fast development of pest is to the pesticide species Influence and Development " article: use synergist can improve the drug effect agent and can improve drug effect, prolong medicament service life, become an important means in the resistance management.Agricultural synergist is also few at present, but requires urgent.The herbicidal effect of molinate also reduces because of resistance strengthens obviously, and sulfonylurea and dinitroaniline are had cross resistance.Report in " agricultural chemicals " the 38th volume the 5th phase " present situation of sulfonylurea herbicide and trend analysis " article: though be that the sulfonylurea herbicide of representative has efficiently with superstar, the wide spectrum characteristic, consumption generally is no more than 100g/hM
2Advantage, but its listing is soon, the report that just has pair weeds to develop immunity to drugs, pesticide resistance has become sulfonylurea herbicide and has used a big obstacle with development.The pesticide resistance problem that solves weed killer herbicide has become the task of top priority.The consumption of all pointing out to reduce weed killer herbicide in above data is to solve the drug-fast basic method that falls careless agent.
It is low to the purpose of this invention is to provide a kind of cost, and herbicidal effect is good, can make the obvious improvement of existing weed killer herbicide herbicidal effect and even fundamentally control the coal-base acid herbicide that its pesticide resistance takes place once again.
The each component weight ratio of coal-base acid herbicide of the present invention is:
Coal-based acid: weed killer herbicide=(0.004-5): 1
Above-mentioned coal-based acid is from weathered coal, and the humic acid substance that extracts in brown coal or the peat also can be a weathered coal, the coal-based organic acid that brown coal or peat obtain through chemical degradation.
Above-mentioned weed killer herbicide is 2 in the phenoxy carboxylic acid herbicides, 4-D; It also can be the chloramben in the benzoic acid herbicide; It also can be the Acetochlor in the acetamide-group herbicides; It also can be the fluometuron in the phenyl ureagroup herbicides; Superstar or metsulfuron-methyl in also can sulfonylurea herbicide; Also can carbamate and thiocarbamate herbicide in molinate or benthiocarb; Can also be glyphosate or the careless fourth phosphine in the organic phosphates weed killer herbicide.
The preparation method of coal-base acid herbicide mixes coal-based acid and weed killer herbicide according to the above ratio, and concrete grammar is as follows:
When (1) weed killer herbicide is liquid, with coal-based acid and weed killer herbicide mixing and stirring in proportion;
When (2) weed killer herbicide is wetting powder, coal-based acid and wettable weed killer herbicide are fully mixed;
When (3) weed killer herbicide is granule, coal-based acid and weed killer herbicide and filler are mixed the back granulation;
When (4) weed killer herbicide is dry suspending agent, with the former medicine of coal-based acid and weed killer herbicide mix be uniformly dispersed after, make thousand suspending agents by weed killer herbicide dry suspending agent manufacturing process.
The present invention has compared following advantage with existing weed killer herbicide:
1. owing to unique synergistic effect of coal-based acid, fundamentally solved the pesticide resistance problem of existing weed killer herbicide.
2. the weed killer herbicide consumption is reduced, with compare consumption minimizing 30-50% without the former weed killer herbicide of coal-based sour modification more than, and prolonged the weeding duration.Because consumption reduces, thereby has reduced the pollution of weed killer herbicide to environment.
3. reagent cost and drug cost are descended significantly, such as 10% superstar's granule (du pont company) wholesale price is 260 yuan/Kg, (coal-based acid: coal-based sour superstar's weed killer herbicide of the superstar) forming can meet or exceed single effect with the superstar by herbicidal effect under dosage the same terms in 1: 1 and when using by weight ratio, and the latter's cost only is the former half, (coal-based sour cost is generally 1-2 unit/Kg), this shows, reagent cost drop by half not only, its dosage (comparing with single superstar) is drop by half also.
4. coal-base acid herbicide of the present invention not only makes effect of herbicides improve, consumption reduces and coal-based acid also can reduce the murder by poisoning of weed killer herbicide to people and animals, coal-based acid simultaneously also has diseases prevention, disease-resistant raising crops anti-adversity, coal-based acid also has very high biostimulation activity to promoting plant growth, and increasing both production and income improves crop quality all very good effect.
