My company in the patent No. of application in 2002 is: 02113260.7 " dry pyrethrum flower pulvis and wetting powder " patent of invention has the following disadvantages: 1) on the prescription, dry pyrethrum flower is pulverized back adding diatomite or talcum powder is made the dry pyrethrum flower powder, under the situation that does not add antioxidant, pyrethrin poor stability, degraded easily; In sealing, stored 2 years under the normal temperature condition, the degraded of dry pyrethrum flower powder reaches more than 25%, has surpassed the active ingredient degraded 5% with interior national standard, decomposes under the situation that temperature raises to reach 50%, and product quality is difficult to guarantee.2) on the prescription, do not add synergist in the dry pyrethrum flower powder, it only plays avoidance effect to insect, does not reach the effect of kill insects, and drug effect can not be given full play of.3) because this prescription needs dry pyrethrum flower powder degree thinner, so will carry out twice pulverizing to the dry pyrethrum flower powder, long processing time, the power consumption height increases cost, and makes a large amount of pyrethrin active ingredient degradeds, because the dry pyrethrum flower powder is along with the degradation speed that diminishes of grain fineness is accelerated, and when carrying out the secondary pulverizing, machine can produce heat, and temperature raises also can accelerate the degraded of pyrethrin.
Summary of the invention
The purpose of this invention is to provide good, the easy degraded of a kind of drug effect, environmentally friendly, to the natural pyrethrin flower powder agent and the preparation method of warm blooded animal safety.
Technical scheme of the present invention is:
The natural pyrethrin flower powder agent is prepared with following raw material: preparing every 100g pollen agent pyrethrum cellulose content is 0.1～1g; Plant resource synergist addition is 1～5 times of pyrethrin content, and plant resource antioxidant addition is 1～3% of a pyrethrum cellulose content, and surplus is a tripolite filling material.
The plant resource synergist is: oil tea fruit powder, oriental wormwood powder and folium eucalypti powder; The plant resource antioxidant is that agent is rosemary, powder and tea polyphenol powder.
The preparation method:
1, chooses dry pyrethrum flower, pulverize once by micronizer;
2, measure the content of pyrethrin in the pyrethrin flower powder, take by weighing the amount of needed pulvis flores pyrethri;
3, add plant resource synergist, plant resource antioxidant and filler, put into mixer and puddle evenly;
4, check pyrethrin flower powder agent sieving rate and pyrethrin content, product packing warehouse-in.
The present invention's raw material preparing natural pyrethrin flower powder agent such as the pyrethrin that adopts plant resource, synergist, antioxidant of filling a prescription, dispersive property is good, has the following advantages:
1, pyrethrin flower powder agent biggest advantage is the insecticide of pure plant source, do not add any chemical substance, and the pyrethrin of other formulations, as: missible oil, microemulsion, wetting powder, in all inevitably add emulsifier, chemical substances such as surfactant so real pure natural has been accomplished in the pyrethrin flower powder agent, organise.
2, tagging property of pyrethrin flower powder agent, so and other its pulvis to have difference to be that powder does not need very thin, drift that this is also less.
Even 3, pyrethrin flower powder agent generation drift phenomenon does not pollute the environment yet, because the pyrethrin flower powder agent is botanical pesticide fully, without any chemical substance, real environment friendly agricultural.
4, after the formulation of pyrethrin was pulvisization, the pesticide processing process was fairly simple, can economize on resources, and reduced production costs.
5, use the pyrethrin flower powder agent can save a large amount of labours, dosage reduces, and dispenser can prolong interval, can save more agricultural chemicals, and the control cost is low.Because sedimentary facies is when evenly on plant for pulvis, rate of recovery height once dusts and can keep the long drug effect phase, thereby can prolong dispenser interval, so can save the agricultural chemicals usage amount, also can reduce workload.
6, the pyrethrin flower powder agent not only can be used for the land for growing field crops, can also be used for protection ground.Protection ground pesticide spraying is difficulty relatively, and conventional spray-on process is because water consumption is big, and not only working condition is poor, inefficiency; and medicament runs off serious; and canopy chamber humidity is gathered increase, strengthened the damage by disease and insect occurrence condition on the contrary, and use pulvis just can address this problem.
7, pyrethrin flower powder agent pesticide application technology is simple, effect is high, the tool operability, is widely used in arid and water scarcity, The mountains are high and the roads are steep, the insect pest that the large tracts of land outburst is caused disaster, the mountain and forest region that needs control rapidly to endanger in a short time.
In a word, natural pyrethrin flower powder agent of the present invention has overcome the shortcoming that prior art exists, and the antioxidant that uses, synergist etc. are entirely botanical material, really realized pure naturalization, environmentally safe, pollution-free, and can economize on resources, production technology is simple, reduces production cost, improves insecticidal effect.The preparation success of natural pyrethrin flower powder agent of the present invention, it is aerial stable to have improved pyrethrin greatly, has improved the control efficiency and the availability of pulvis.The natural pyrethrin flower powder agent has good control efficiency to most of agriculture vegetable-crop pest-insects such as imported cabbageworm, diamond-back moths, is a kind of desirable insecticide of producing pollution-free food, pollution-free food, organic food.
