Abstract

The present invention relates to coal-based acid insecticide which is formed by uniformly mixing coal-based acid and insecticide according to the weight ratio of the coal-based acid and the insecticide of 0.006 to 1. The problem of the drug resistance of the existing insecticide is fundamentally solved, the dosage of the insecticide is reduced, and cost is reduced. The coal-based acid can reduce the toxic hazard of germicide for people and livestock, and meanwhile, the coal-based acid also has various functions of preventing diseases, resisting diseases, enhancing the bumping resistance performance of crops, etc.; therefore, the coal-based acid insecticide has favorable disinsection effect, and has better effect on promoting crop growth, increasing yield and improving crop quality.

Description

Coal based acid pesticide

The present invention relates to a kind of agricultural chemicals lethane, relate in particular to a kind of coal based acid pesticide.

Along with using in a large number for a long time of chemical pesticide, because biomolecule resistant strengthens, cause drug effect to descend, consumption is increasing, and to increasing severely harm and day of environment for human survival, therefore many medicaments lose using value so that be eliminated.The approach one that solves this class problem at present is that the synthetic novel pesticide of research replaces old kind, this method the time with and funds on consumption all very surprising, according to reports, develop a kind of novel pesticide the nineties, need screening compounds to reach more than 20,000, expensive 8,000 ten thousand dollars.The second approach is to start with from improving existing pesticide efficacy, selects for use existing pesticide efficacy is recovered and improve the method that the material of drug effect combines by physics, chemistry or physico chemistry to be combined into new agricultural chemicals.

Insecticide is to use early in the chemical pesticide, and kind is maximum, the agricultural chemicals monoid that consumption is very big, and in agricultural production, various insects are very serious to the harm of crop, are one of maximum harm that causes the agriculture underproduction.Show P83-84 page or leaf introduction in " combined use of pesticides and mixture " book according to Zhang Ruiting, in general a kind of chemical insecticide serious resistance will occur at a regional continuous application 3-5, even loses desinsection effectiveness fully.Ail, A.M. and Ayad, F.A. in that " Proceedings of thd 8th BritishInsecticide and Fungicide Conference (1975) has been described in detail the situation that some kinds of insecticides in use produce resistance in paper P763).Such as use sea, nuvacron control cotton field spodoptera in Egypt, only the triennium nuvacron has just lost the ability of controlling this insect fully in Egypt.Because the serious existence of pesticide resistance problem, countries in the world have to seek redress capturing on the resistance to insecticides problem, the method applied in the present invention is exactly an effective way that solves the resistance to insecticides problem.

It is low to the purpose of this invention is to provide a kind of cost, good disinsection effect, and can suppress the coal based acid pesticide that resistance takes place.

The object of the present invention is achieved like this: coal-based acid and insecticide are mixed by a certain percentage, and the weight ratio of coal-based acid and insecticide is 0.006-1.5: 1.

When (1) insecticide is liquid, with coal-based acid and insecticide mixing and stirring in proportion;

When (2) insecticide is wetting powder or soluble powder, coal-based acid and wettable or soluble powder are mixed;

When (3) insecticide is granule coal-based acid and insecticide are mixed the back granulation.

Described coal-based acid can be the humic acid substance (ulmic acid, humic acid, fulvic acid) that extracts in weathered coal, brown coal, the peat, also can be the coal-based organic acid that obtains through chemical degradation from weathered coal, brown coal, peat.

Described insecticide is the nuvacron in the organophosphorus insecticide, acephatemet, phosphamidon, parathion, it also can be the furans pellet in the carbamate insecticide, Methomyl can also be the dimehypo in decis, sumicidin and the sandworm toxin insecticide in the pyrethroid insecticides, Chlorphenamidine.

The present invention has compared following advantage with existing insecticide:

1. because the special synergistic effect of coal-based acid significantly improves the insecticide insecticidal effect that produces resistance, fundamentally solved the pesticide resistance problem of existing insecticide.

2. the insecticide consumption is reduced, compare with the former insecticide without coal-based sour modification, consumption can reduce more than the 35-60%, and duration of efficacy is prolonged.

3. coal-based acid can significantly reduce toxicity of pesticides, thereby original high toxicity insecticide safety in utilization is improved, expanded range is added dosage and reduced, thereby has reduced agricultural chemicals significantly to people and animals' murder by poisoning with to the pollution of environment.

4. reagent cost and drug cost are descended significantly, and (Xinghe chemical industry Co., Ltd) is 20 yuan/kg such as 40% nuvacron missible oil wholesale price.(nuvacron: coal-based acid) the coal-based sour nuvacron insecticide of forming can meet or exceed single effect with nuvacron at the identical insecticidal effect of dosage in 1: 0.8 and when using by weight ratio, and coal-based acid---nuvacron descends 40% than single with the nuvacron cost, meanwhile compares consumption with single phosphorus consumption of a specified duration and has reduced nearly 50%.

5. coal based acid pesticide of the present invention not only makes the insecticide drug effect increase substantially, consumption reduces, and the decomposition that coal-based acid is deposited process to the inhibition agricultural chemicals has remarkable result, thereby the insecticide shelf stability is significantly improved, coal-based acid simultaneously also has diseases prevention, disease-resistant raising crop anti-adversity energy, reduce the uniqueness effectiveness that damage by disease and insect takes place, coal-based acid still is the very high plant stimulin of a kind of biologically active, to promoting plant growth, increasing both production and income and improve crop quality etc. and all have very good effect, the effect of therefore using coal based acid pesticide to have to achieve many things at one stroke.
