Abstract
The present invention discloses one kind of pesticide for preventing and killing soil nematode and other pests and its preparation. Emamectin benzoate as main material is mixed with solvent, emulsifier and penetrant to form the pesticide oil cream. The pesticide oil cream is diluted and irradiated to roots or sprayed to soil so as to prevent and controlling meloidogyne hapla and other pests. It has simple use, low consumption, high pesticidal effect, fast degradation and no residue, and may be used in produce green food material.
Description
Technical field
The present invention relates to the control medicine and the preparation method of soil pests, relate to a kind of medicament and preparation thereof that prevents and treats nematode and other insects in the soil specifically.
Background technology
In recent years; owing to be subjected to protection the restriction of economic interests; plant monocrop year after year; crop rotation rotation of crops difficulty; cause the nutrient imbalance of soil; excessive use causes soil beneficial microorganism kind to reduce to agricultural chemicals in addition, has caused that nematode and other insects are on the rise in the soil, and the yield and quality of its crop is all seriously influenced.Specifically the continuous cropping time long more, its extent of injury is big more.Thereby in order to solve this practical problem, effectively the growth of elimination or inhibition nematode etc. provides a soil that guarantees healthy growth to crops, just must be to disinfecting soil.Uses at present that the drug main of sterilizing will adopt that methyl bromide is fumigated, lime oxygen, Avermectins missible oil etc.But these selections of killing drug ingedient are used, and can bring following problem:
1, methyl bromide.It is a kind of insecticide, bactericide of wide spectrum, can kill the following most of biologies such as nematode that comprise effectively.But it destroys ecological environment of soil, destroys atmospheric ozone layer, and people and animals are had severe toxicity.
2, calcium cyanamide.The large usage quantity of single use also will need a sun-drenched environment to its overlay film of digging during use, and the processing time is longer, takes a lot of work during operating cost.And slow after handling to the useful repopulate of its soil, the possibility that crop has poisoning to produce.
3, Avermectins missible oil.Can have certain effect to nematode, but along with making soil pests have certain pesticide resistance after long-term a large amount of the use, can fade to the inhibition effect of nematode, the soil disinfection effect reduces.
4, above-mentioned medicine practices, and no matter is to be used for the face of land or underground using, and all can't satisfy and can suppress the infringement of nematode to crop, can effectively protect soil environment again.Therefore seek a kind of effectively and can become a urgent problem to the medicine of its disinfecting soil.
Summary of the invention
The objective of the invention is for solving the above problems, a kind of effective recovery soil micro-ecosystem balance is provided, the medicament of nematode and other insects in the control soil of increase crop yield.
Another object of the present invention also provides the above-mentioned medicaments preparation method of finishing.
For achieving the above object, the present invention finishes by the following technical programs.
Medicament of the present invention is to make by following percentage by weight:
Choose purity at the former medicine 0.1-20% of the stupid formates of the Affirm (Merck Co.) more than 60%, solvent 39-70%, emulsifier 4.45-31%, bleeding agent 4.45-31%.
In the present invention, described solvent is to be selected from toluene, dimethylbenzene, any of absolute ethyl alcohol.
In the present invention, described emulsifier is to be selected from any of neopelex, calcium dodecyl benzene sulfonate.
In the present invention, described bleeding agent is JFC.This JFC is a nonionic surface active agent, fatty alcohol-polyoxyethylene ether.
In the present invention, choose purity at the former medicine 1% of the stupid formates of the Affirm (Merck Co.) more than 60%, solvent 70%, emulsifier 13%, bleeding agent 16%.
Medicaments preparation method involved in the present invention is as follows:
Choose the former medicine of emamectin-benzoate by weight percentage, with a small amount of solvent dissolving, add the bleeding agent mixing then earlier, add the emulsifier mixing again, last solvent by weight additional surplus carries out mixing, promptly makes the missible oil medicament.
The good effect that medicament of the present invention has is:
1, the medicament that makes of the present invention and use compliance with environmental protection requirements, degraded is fast, and noresidue does not destroy useful population in the soil, and reduces the poisoning to crop.
2, medicament of the present invention uses simple to operately, can fall ill according to soil nematodes and irritate root after weight dilutes in proportion, dip in root or spray soil, compare the high 1-10 of an Avermectin order of magnitude, be difficult for developing immunity to drugs, thereby it is few to have a consumption, effective to soil disinfection.
3, medicament of the present invention can be widely used in the root-knot nematode (as vegetables, tobacco, strawberry etc.) in the control proportion of crop planting; Simultaneously also to cockchafer Class A, acupuncture needle insects, mole cricket class, nocturnal moth class, Paederus densipennis Bernh, grub category, cutworm class, root sky bovine, root stinkbug class, maggot, other insects such as diptera mosquito class larva of burying.
4, medicament of the present invention has the soil micro-ecosystem of recovery balance, increases the characteristics of crop yield.
Embodiment
Below in conjunction with specific embodiment, the present invention is further illustrated, should be understood that institute only is used to the present invention is described and is not used in the restriction scope of the invention to embodiment.
At first choose purity at the former medicine 1.43kg of 70% emamectin-benzoate, the xylene solvent that adds 30kg, dissolve former medicine, after treating former medicine dissolving, mixing behind the adding fatty alcohol-polyoxyethylene ether bleeding agent 10kg adds 8kg neopelex emulsifier mixing again, adds 37.7kg xylene solvent mixing at last again, promptly make the missible oil finished product, can use after the packing.
The application of this medicament when proportion of crop planting, with the actual conditions of medicament according to scholar's earth nematode morbidity weight, is irritated root by the laggard row of proper proportion dilution medicament.
Above-mentioned medicament is except that this crop being irritated root or dipping in the root use.Also soil can be sprayed, same action effect can be reached.
If when being used for spraying method, should spray medicament to its soil earlier, then its back field planting of ploughing is got final product.
