Abstract
The plant pesticide powder for preventing and killing pest in stored grains consists of celas trusangulatus extractive with polybasic ester of dihydroagarofuran effective component and stuffing. The preparation process of the plant pesticide powder includes extracting effective component in celas trusangulatus root bark with organic solvent and subsequent mixing with stuffing to form powdered preparation. The advantages of the present invention include less consumption, high attachment, high pesticidal effect and convenient use.
Description
Technical field: the present invention relates to a kind of plant insecticide preparation that is used to prevent and treat pest of stored grain, belong to the field of pesticide technology.
Background technology: the annual storage in whole world grain because of insect cause harm cause with a toll of more than 10%.In China; pest of stored grain relies on controls such as pest control phosphorus, phosphine for a long time; because the single and unreasonable use of pharmacy variety; not only produced serious pesticide resistance; but also bring serious problems such as residual residual hazard; therefore both at home and abroad the research and development of always exploring the non-environmental pollution control measure, particularly vegetable insecticide of pest of stored grain enjoy attention, but do not see that so far the vegetable insecticide product appearance that is specifically designed to the protection of storage grain is arranged.
Wu Wenjun once was reported in and utilizes vegetable insecticide root bark of celastrus angulatus powder that corn weevil is had better prevention effect [Wu Wenjun, the research of pesticide plant Celastrus angulatus, agricultural chemicals 1991,30 (6): 10～12 in the laboratory; Wu Wenjun etc., the Celastrus angulatus extract is to control action and the mechanism of corn weevil population, grain storage 1998, (5): 9～13].
But because root bark of celastrus angulatus is a vegetable fiber, therefore be difficult to pulverize by 200 mesh sieves, though the powder by 200 mesh sieves, because of himself attribute (structure and compatibility) also only has certain adhering on rice, show certain preventive effect, and, in fact polluted rice because of its consumption big (0.4%), make it become pink, and to raw grain or seeds such as corn, wheats, because of its smooth surface, powder is difficult to adhere to, and preventive effect is very poor.In the laboratory test hardship is criticized the rattan root bark extract with acetone solution post processing storage grain,, in production practices, can't implement, also can't form product though favorable effect is arranged.Therefore, fail the Celastrus angulatus preparation is applied to the control of pest of stored grain so far.
Summary of the invention: purpose of the present invention just provides that a kind of tack is strong on storage grain, consumption is few, the Celastrus angulatus insecticidal pulvis of the worry of noresidue residual hazard, not only pest of stored grain is had good control efficiency, and to person poultry safety, nuisanceless.
Celastrus angulatus pulvis of the present invention mainly is made up of the Celastrus angulatus extract and the inert filler diatomite that with the dihydroagarofuran are active ingredient.The shared mass percent of this each component of Celastrus angulatus preparation is as follows:
The root bark of celastrus angulatus extract 0.1～70% that contains the polynary ester of dihydroagarofuran
Inert filler diatomite 30～99.9%
Manufacture method of the present invention comprises the steps:
A. with root bark of celastrus angulatus oven dry, pulverizing, be transferred to extractor, add benzene and carry out refluxing extraction, get the Celastrus angulatus extract.
B. the extract of steps A gained is changed in the reactor of band decompressor, be concentrated into and no longer include solvent and reserve, emit remaining liq in the still, be the extract that contains the polynary ester of active insecticidal components dihydroagarofuran.
C. with inert filler diatomite drying after the airslide disintegrating mill ultramicro grinding to powder 99.5% by 325 mesh sieves.
D. with the extract of step B gained with acetone solution after inert filler by sprayer unit and step C gained in mixer, mix, make the Celastrus angulatus pulvis.
Accompanying drawing is a technological process block-diagram of the present invention.
Compared with prior art, Celastrus angulatus insecticidal pulvis of the present invention has the following advantages:
A. consumption is few. The dosage of prior art control pest of stored grain is that 0.4% (root skin powder accounts for the mass percent of handled thing, and is lower With), Celastrus angulatus insecticidal agent pulvis dosage of the present invention is 0.05%.
B. tack is good, the preventive effect height. Prior art is poor because of tack, and can not effectively control raw grain or the kinds such as wheat, corn Pest damage during son is stored, and Celastrus angulatus insecticidal pulvis of the present invention is ultra tiny powder, contained day of Celastrus angulatus extract Right sticker composition and filler attribute thereof and have well attachedly, so the grain such as the smooth corn of effects on surface, wheat have very Good protective effect.
C. easy to use. During warehouse-in the Celastrus angulatus insecticidal pulvis is admixed raw grain or seed gets final product, and do not affect the germination percentage agent of seed The flavor quality of raw grain.
Actual insect protected result (table 1) shows that pulvis of the present invention is admixed corn seed or wheat seed with 0.05% dosage, and is complete Entirely can control sitophilus zea-mais harm.
Table 1 Celastrus angulatus insecticidal pulvis to the control effect process 7d of sitophilus zea-mais after the death rate (%) behind the death rate (%) 50d behind the death rate (%) 21d behind the death rate (%) 14d

Embodiment:
Learn from else's experience ultra micro diatomite (99.5% by the 325 mesh sieves) 500g of comminution by gas stream puts into to smash at a high speed and mixes the machine barrel.Take by weighing the benzene extractives 100g of root bark of celastrus angulatus, under stirring at low speed, spray into barrel behind the adding 100ml acetone solution with air compressor machine.Last smashing at a high speed mixed 10min, flings to solvent in fume hood, promptly makes the Celastrus angulatus insecticidal pulvis that contains extract 20%.
Claims (3)
1. plant insecticide pulvis of preventing and treating pest of stored grain is to be the preparation of active ingredient with the polynary ester of the dihydroagarofuran in the root bark of celastrus angulatus, it is characterized in that said preparation made through ultramicro grinding by root bark of celastrus angulatus extract and inert filler.
