Abstract
Disclosed is a Bacillus thuringiensis (Bt) biological pesticide effervescence tablet, which comprises Bt biological pesticide raw powder and findings including wetting agent, emulsifying agent, crumbling agent, and binding agent. The constituents include Bt biological pesticide raw powder, lignin sulfonic acidic sodium, stearic acid, 2-hydroxybenzoic acid, sodium hydrogen carbonate, and starch. The invention has the advantages of less contamination, easy transportation, long keeping time and easiness in application.
Description
Technical field
The present invention relates to a kind of preparation of biopesticide formulation, particularly the bacillus thuringiensis biopesticide.
Background technology
At present, bacillus thuringiensis (Bacillus Thuringiensis, Bt) biopesticide mainly contains pulvis, wetting powder, emulsion and four kinds of formulations of aqueous suspension agent.Owing to contain compositions such as albumen, spore, fermentation residue in the Bt biopesticide,, cause the shelf-life shorter so emulsion and aqueous suspension agent are putrid and deteriorated easily.And pulvis needs uses of dusting of special-purpose medical instruments, is easy to cause user's suction, and concurrent fecula agent is drifted about, contaminated environment.Therefore, the emulsion of Bt, aqueous suspension agent and pulvis are not popular to people, and be very rare on market.The Bt wetting powder is comparatively commonly used, and is soluble in water, and spray application still, needs to be poured in the water and stirring and dissolving before the use, be easy to be infected with on user's the skin.Therefore, the novel form of Bt biopesticide is demanded exploitation urgently.
Effervescent tablet is a kind of novel form that occurs in recent years, mainly form by former medicine, wetting agent, dispersant, disintegrant and binding agent, be characterized in efficient, pollute less, storing is convenient, easy to use, represented the developing direction of pesticides new formulation and new operation technique.(2000,2:P6-7) effervescent tablet of having reported chemical pesticide such as tpn, benthiocarb, dichloro Bian and second west is succeeded in developing " Fujian chemical industry "." agricultural chemicals " (2001,40,11:P9-11) reported that the diflubenzuron effervescent tablet succeeds in developing.But these effervescent tablets all belong to the chemical pesticide formulation, and ingredient is only limited to chemical scope.
Summary of the invention
The invention provides a kind of prescription of the Bt of production biopesticide effervescent tablet, increase a kind of formulation of Bt biopesticide, it is few that Bt is polluted, and is easy to storing, and long shelf-life is easy to use.
Bt biopesticide effervescent tablet is made up of the former powder of Bt biopesticide and auxiliary material wetting agent, dispersant, disintegrant, binding agent, composition is that the former powder of Bt biopesticide, wood are planted plain sodium sulfonate, stearic acid, salicylic acid, sodium bicarbonate, starch, and the weight ratio of each composition is followed successively by 10～800: 0.3～30: 0.3～30: 0.1～90: 0.1～70: 0.2～50.
Wherein wood is planted the effect that plain sodium sulfonate both can play wetting agent, increases the solvability of Bt, can play the effect of dispersant again, promotes the even dispersion of Bt; Disintegrant sodium bicarbonate and salicylic acid play stirring and mixing effect; Adhesive starch combines all the components when compressing tablet.
Product that the present invention obtains is a tablet, produces bubble in water, and tablet is disintegration gradually, and the Bt pulvis is distributed in the water equably after the disintegration, both sprayablely is applied to various crops, also can directly throw and execute in the paddy field, does not need special medical instruments.
The toxicity evaluation of this product is 16000--32000IU/mg, and 3 years shelf-lifves, the normal temperature sealing is preserved.
Embodiment
(1) table 1 composition takes by weighing raw material
Table 1Bt biopesticide effervescent tablet composition (gram)
(2) above-mentioned raw materials is mixed, be pressed into tablet with tablet press machine;
(3) pack, normal temperature is preserved, and the shelf-life is 3 years.
The toxicity evaluation of Bt biopesticide effervescent tablet is 16000--30000IU/mg.During use, can render in the sprayer water disintegration, salicylic acid in the tablet and sodium bicarbonate are met the water post-foaming, and bubble promotes effervescent tablet and moves about in water, and active ingredient can promptly be distributed in the water, form uniform suspension, spray application is in various crops again.Also Bt biopesticide effervescent tablet directly can be thrown in the paddy field, active ingredient can be diffused into the everywhere in rice field after the disintegration.Bt biopesticide effervescent tablet integrates the advantage of biopesticide and effervescent tablet, easy to use, be easy to metering, can reduce being infected with to the operator, environmentally friendly, nontoxic to people, animal, be applicable to the control of 100 various pests on grain, cotton, vegetables, melon and fruit, greenery patches and the forest.
Claims (1)
1, a kind of bacillus thuringiensis biopesticide effervescent tablet, it is characterized in that, Bt biopesticide effervescent tablet is made up of the former powder of Bt biopesticide and auxiliary material wetting agent, dispersant, disintegrant, binding agent, composition is that the former powder of Bt biopesticide, wood are planted plain sodium sulfonate, stearic acid, salicylic acid, sodium bicarbonate, starch, and the weight ratio of each composition is followed successively by 10～800: 0.3～30: 0.3～30: 0.1～90: 0.1～70: 0.2～50.
