Abstract
The biological insecticide with special effect on vegetable insects is prepared with active components including powdered derris root containing elliptone, thuricide powder and nucleopolyhedrosis virus powder, assistant (capsaicine), wetting agent and suspending agent and features high effect, low cost and no other toxic by-effect.
Description
The invention belongs to insecticidal materials, is a kind of to the specific agricultural biological insecticide of vegetable-crop pest-insect.
Kill the chemical insecticide of " Rogor " or " blinds green grass or young crops " class commonly used such as greengrocery insect such as mythimna separata, bean worm, aphid, two spotted spider mite, cabbage caterpillar, diamondback moth larvae, adult at present, long-term this class medicine that uses can make insect develop immunity to drugs, influence its disinsection efficiency, and can cause environmental pollution, its residual life, also can endanger the safety to people and animals.And another kind of as contain rotenone and mushroom (as white muscardine fungi, bacillus thruingensis) though etc. the Biocidal preparation of effective ingredient can overcome the deficiency of chemical insecticide to a certain extent, but this class biological source insecticide is more common in single agent and is used, as only containing the medicine of rotenone, it is narrower to exist the desinsection scope, deficiencies such as the strong inadequately and insecticidal mechanism dullness of drug effect.
The object of the present invention is to provide a kind of is active principle with the derris root powder, bacillus thuringiensis,Bt powder and the nucleopolyhedrosis virus powder that contain rotenone, and the wettable biological insecticidal dust of interpolation auxiliary agent (peppery element), wetting agent (biological Xanthan gun) and suspending agent (drawing back powder), this insecticide can be widened the kind of kill pests, stronger drug effect is arranged so can overcome the existing in prior technology deficiency.
The proportioning and the compounding process that prepare required each material of this insecticide are:
A kind of agricultural wettable biological insecticide is to contain the derris root powder of a certain amount of rotenone, the bacillus thuringiensis,Bt powder that contains a certain amount of gemma is an active principle with the powder that contains a certain amount of nucleopolyhedrosis virus, being mixed with appropriate amount of addition agent, wetting agent, suspending agent forms, and it is characterized in that the relative weight ratio of three kinds of active principle derris root powder, bacillus thuringiensis,Bt powder, nucleopolyhedrosis virus powder is 1: 0.75-1.6: 0.20-0.5; The surplus material that is added is to be that auxiliary agent, biological Xanthan gun are wetting agent, draw back powder or dextrin is a suspending agent with peppery element; The ratio of the gross weight of each surplus material and each active principle gross weight amount is 1: 5-6;
Preparation and compounding method are:
Producing of A, derris dust: after derris root decaptitated, be cut into the segment of 30-60mm, put into crusher for crushing, get its powder with the square-bottomed bamboo basket sieve sieve of certain order number again;
Producing of B, bacillus thuringiensis,Bt powder: do medium with wheat bran skin, cotton benevolence cake, ash, after the high-temperature sterilization, apply 20-40mm on the upper berth, cement flooring thick, and room temperature keeps 28 ℃-30 ℃, puts bacterial strain in medium.Mix thoroughly, cover gauze fermentation 24 hours, throw off gauze then and dry the base-material that has carried disease germs, get its powder with the square-bottomed bamboo basket sieve of certain order number, sealing is preserved standby;
C, be mixed: in temperature is 10 ℃-25 ℃ drying room, get peppery plain the interpolation in the derris dust earlier, mix thoroughly dry after, to contain in proportion pepperyyer element derris root powder, bacillus thuringiensis,Bt powder, nucleopolyhedrosis virus powder and Xanthan gun powder, draw back powder and drop in the agitator and mix thoroughly, get final product these biological insecticides, pinkiness, its water content should be lower than 3%, and sealing is placed on the moon place of drying in the air and stores;
D, using dosage: get a certain amount of this Biocidal pulvis and spray with the 500-800 water-soluble dilution back of separating doubly.
The relative weight ratio of effective component content and each material of surplus is in each material:
The content of rotenone should be 6-9% in the derris root powder, and the content of gemma is hundred million of 60-100/gram in the bacillus thuringiensis,Bt powder, and the content of virion is hundred million of 80-100/gram in the nucleopolyhedrosis virus powder; Peppery element, biological Xanthan gun, the relative weight ratio that draws back the powder three are 1: 1.0-1.5: 0.9-1.8.
The specification of used utensil is:
The square-bottomed bamboo basket sieve that sieve is got the derris root powder is 150 orders, and the square-bottomed bamboo basket sieve that sieve is got the bacillus thuringiensis,Bt powder is 120 orders.
Embodiments of the invention are as follows:
1,100 kilograms of these insecticides of preparation need contain 7% rotenone 41 kilograms in derris root powder, contain 7,000,000,000 gemma/grams 34 kilograms in bacillus thuringiensis,Bt powder, contain 9,000,000,000/restrain 10 kilograms in the powder of nucleopolyhedrosis virus, peppery plain 4 kilograms of the amount of auxiliary of being added, 6 kilograms of biological Xanthan guns, draw back 5 kilograms in powder.Produce and be mixed process as described above.
2,100 kilograms of these insecticides of preparation need contain 8% rotenone 38 kilograms in derris root powder, contain 8,000,000,000 gemma/grams 35 kilograms in bacillus thuringiensis,Bt powder, contain 10,000,000,000/restrain 10 kilograms in the powder of nucleopolyhedrosis virus, peppery plain 6 kilograms, 6 kilograms of biological Xanthan guns, draw back 5 kilograms in powder.Produce and be mixed process as described above.
3,100 kilograms of these insecticides of preparation need contain 9% rotenone 36 kilograms in derris root powder, contain 9,000,000,000 gemma/grams 35 kilograms in bacillus thuringiensis,Bt powder, contain 10,000,000,000/restrain 10 kilograms in the powder of nucleopolyhedrosis virus, peppery plain 6 kilograms, 6 kilograms of biological Xanthan guns, draw back 7 kilograms in powder.Produce and be mixed process as described above.
This prepared wetting powder in use should be sprayed by the 500-800 water-soluble dilution back of separating doubly.
The obtained technological progress of the present invention is:
1, the comprehensive three kinds of biogenic effective ingredients as kill pests of this pesticide, insecticidal action complements each other, not only strengthen the effect of this pesticide, and can be widely used in the control to various pests such as low instar bollworm grub, adult, mythimna separata, bean worm, aphid, red spider, cabbage caterpillar, diamondback moth larvae, adult, vegetable aphid, dish mites. The greengrocery insect pest there is special efficacy.
2, because the present invention is a kind of biological insecticides, the mechanism of control diseases and pests of agronomic crop is pure biological so in use to people and animals and pest natural enemy, there is not poison to pay effect, there is not the toxic residue problem, environmentally safe after spraying can not destroy and affect the intrinsic taste of vegetables fruit.
