Abstract
The present invention relates to a bacillus thuringiensis oil suspension pesticide for spray-controlling forest pests by ultraloe dose. It is made of bacillus thuringiensis raw powder, solvent, dispersing agent and thickening agent through a certain preparation process. The solvent includes diesel oil and dimethyl O-phthalate, etc. the dispersing agent includes sodium lignosulfonate, nekal and NNO, etc. and the thickening agent includes gas-phase SiO2, bentonite, aluminium stearate and gum tiagacanh powder, etc. Said suspension pesticide can obtain good pests-killing effect for killing the forest pests of pine caterpillar, fall webworm and yangshanzhou moth etc. The controlling effects of said suspension pesticide for killing pine caterpillar for 2,4,6 days are 50.4%-64.8%, 69.1%-84.1% and 89.9%-96.8% respectively.
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 the mixture of any one or any two solvent in diesel oil, machine oil, soya-bean oil, repefral and the solvent known in those skilled in the art.
Described dispersant is sodium lignin sulfonate, draw back in powder, NNO, MF, IS dispersing and the dispersant known in those skilled in the art any one.
Described thickener is gas phase SiO
2, in bentonite, aluminum stearate, long jiao powder, xanthans and the thickener known in those skilled in the art any one.
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.
