Abstract
The present invention relates to Bacillus thuringiensis oil suspension insecticide, particularly to insecticide for spraying, preventing and killing forestry pests by an ultra-low dosage. The Bacillus thuringiensis oil suspension insecticide is prepared from Bacillus thuringiensis initial powder, a solvent, a dispersing agent and a thickening agent, wherein the solvent comprises diesel oil, dimethyl phthalate, etc., the dispersing agent comprises sodium lignosulphonate, nekal, NNO, etc., and the thickening agent comprises gas-phase SiO2, bentonite, aluminum stearate, gum tragacanth powder, etc. The suspension insecticide has the better killing effects on the forestry pests, such as pine caterpillars, clostera anachoreta, etc., and has the advantages of no toxicity for people and livestock, safety for natural enemies of the pests, no environmental pollution, no need of water, strong permeability and adhesiveness, evaporation resistance, rainwash resistance, long effective periods and storage resistance; the present invention has a synergistic effect. The preventing and killing effect of the suspension insecticide is 50.4% to 64.8%, 69.1%to 84.1% and 89.8%to 96.8% on 2, 4 and 6 days of the pine caterpillars, etc.
Description
Technical field the present invention relates to a kind of insecticide that is used for ultra low volume spray control forestry pest.
Background technology bacillus thuringiensis,Bt (Bacillus thuringiensis, be called for short Bt) be the important insect disease indigenous bacteria of a class, be research at present both at home and abroad at most, output is maximum, the quasi-microorganism insecticide that is most widely used, to some important forestry insects, has good control efficiency as dendrolimus punctatus, fall webworm, poplar caterpillar, gypsymoth and looper etc.The Bt formulation that is used for forest pest control at present mainly is aqueous suspension agent and wetting powder.Because these two kinds of formulations need dilute with water in the aerial spraying process, the anti-evaporating ability is relatively poor, and fogdrop diameter diminishes, and causes drift, influences result of use.And to reach enough settling amounts, and the necessary low-latitude flying of aircraft, efficient is low, and may cause fatal crass's tragedy.Therefore must develop the special-purpose formulation that is suitable for preventing and treating forestry pest.
Oil-suspending agent is that one or more pesticide active ingredients (wherein have at least a kind of for the former medicine of solid) form high dispersive, stable suspension system in non-water system dispersion medium.Compare with formulations such as aqueous suspension, wetting powders, advantages such as it has, and permeability and adhesiveness are strong, anti-evaporating, storage tolerance and synergy, and need not add water when using, especially be fit to aircraft ultra low volume spraying control forestry pest.Based on these advantages, development bacillus thuringiensis,Bt oil-suspending agent is particularly necessary.
The bacillus thuringiensis,Bt oil-suspending agent is a kind of novel form that is used for ultra low volume spray control forestry pest, occurred on the U.S., Canada and other places, but its prescription and manufacture craft is not all published.Domestic some unit is carrying out the research of this formulation, also do not form product, published one piece " Development of ULV Formulation of Bacillus thuringiensis " (seeing Chinese biological control 17 (4) P167-169) article, he just represents with code name, does not list concrete prescription.
Summary of the invention the objective of the invention is according to above-mentioned situation, aim to provide a kind of to forestry pests such as pine caterpillars, fall webworm, poplar caterpillar have better killing effect, nontoxic to people and animals, to natural enemies security, need not add water in free from environmental pollution, the use, permeability and adhesiveness are strong, anti-evaporating, resistance of rainwater washing against, lasting period length, storage tolerance, the oily suspension pesticide of bacillus thuringiensis,Bt of synergistic effect is arranged.
The implementation of the object of the invention is, bacillus thuringiensis,Bt oil suspension pesticide is formulated by the former powder of bacillus thuringiensis,Bt, solvent, dispersant, thickener, and wherein the percentage by weight of each component is:
Bacillus thuringiensis,Bt 8～38% dispersants 0.8～6%
Thickener 0.7～6% solvent 55～85%
Described solvent is any one or any two kinds mixture in diesel oil, machine oil, soya-bean oil, the repefral,
Described dispersant is sodium lignin sulfonate, draw back in powder, naphthalene sulfonic acid-formaldehyde condensation product sodium salt, condensation compound of methyl naphthalene sulfonic acid and formaldehyde, the polyoxyethylene carboxylate any one,
Described thickener is gas phase SiO
2, in the bentonite, aluminum stearate, long jiao powder, xanthans any one.
The english term of the naphthalene sulfonic acid-formaldehyde condensation product sodium salt in the dispersant of the present invention is NNO, and the english term of condensation compound of methyl naphthalene sulfonic acid and formaldehyde is MF, and the english term of polyoxyethylene carboxylate is IS dispersing.
Solvent of the present invention, dispersant, thickener also comprise any one in solvent known in those skilled in the art, dispersant, the thickener.
Beneficial effect of the present invention:
1, forestry pests such as pine caterpillars, fall webworm, poplar caterpillar have favorable effect;
2, people and animals nontoxic, to pest natural enemy safety, free from environmental pollution;
3, need not add water in the use, especially be fit to lack of water mountain area forest pest control;
4, have that permeability and adhesiveness are strong, advantages such as anti-evaporating, resistance of rainwater washing against, lasting period are long, storage tolerance and synergy.
