Technical scheme of the present invention is: a kind of Chinese herbal medicine merges the botanical fungicide extracting, its active ingredient merges extraction by the Chinese herbal medicine of following weight ratio and forms, 20～30 parts of kuh-sengs, 20～50 parts of dandelions, 50～80 parts of the roots of langdu, 20～40 parts of Flos Artemisiae finitaes, 10～30 parts of gall nut.
Further, active ingredient of the present invention merges extraction by the Chinese herbal medicine of following weight ratio and forms, 22～28 parts of kuh-sengs, 25～45 parts of dandelions, 60～70 parts of the roots of langdu, 25～35 parts of Flos Artemisiae finitaes, 15～25 parts of gall nut.
Further, the preparation method that Chinese herbal medicine of the present invention merges the botanical fungicide extracting is: by each taste Chinese herbal medicine dried and crushed, in ethanol, soak 2～8 hours, circulate and extract 2～8 times, each extraction 40～60 minutes, removes the dregs of a decoction, and extract is placed in Rotary Evaporators Vacuum Concentration, in concentrate, add appropriate insecticides adjuvant, the liquid preparation making that stirs is exactly that Chinese herbal medicine of the present invention merges the botanical fungicide extracting.
Further, described insecticides adjuvant percentage by weight in liquid preparation is 1～10%.
Further, described insecticides adjuvant comprises bleeding agent and preservative.
Further, described bleeding agent comprises one or more in polyoxyethylene nonylphenol ether, fatty alcohol-polyoxyethylene ether, Tween 80.
Further, described preservative comprises Sodium Benzoate and/or potassium sorbate.
Advantage of the present invention is:
It is to have done a large amount of laboratory tests and field control effectiveness test screens perfect result that Chinese herbal medicine of the present invention merges the Chinese herbal medicine compatibility of the botanical fungicide extracting and ratio, its compatibility is scientific and reasonable, there is broad spectrum activity good, bactericidal effect is remarkable, instant effect, efficiency time is long, and the advantage such as can not develop immunity to drugs.
Chinese herbal medicine of the present invention merges the botanical fungicide extracting and degrades at natural world, agricultural chemicals derives from nature, do not pollute the environment and agricultural product, in environment and human body, can not form accumulation toxicity, comparatively safe to people and livestock, there is the feature of low toxicity, low-residual, the production of nuisanceless green vegetables, grain, fruit is had to positive meaning.
In preparation, also add bleeding agent and preservative, increase stability and the efficiency time of insecticide.
