Description

A kind of Pesticide with Chinese medicinal material

Technical field

The present invention relates to technical field of agricultural insecticide, be specifically related to a kind of non-harmful Pesticide with Chinese medicinal material.

Background technology

At present, peasant household all lacks the ABC of proper use of agricultural chemicals, and most peasant household only prevents and treats with chemical pesticide, and reason is very simple: good disinsection effect, instant effect.Also have part peasant household to be careless about practical technique, once think that control efficiency is not good, just strengthen dosage, result makes damage by disease and insect create pesticide resistance.When having had drug-fast damage by disease and insect again when endangering the vegetables in field, just use larger dose to prevent and treat.Vicious circle like this, the residue of pesticide of vegetables will increase greatly.The peasant household more seriously had also breaks rules and regulations on vegetables, use taboo, limit agricultural chemicals, and after medication, the safety interval of Pesticide use does not also arrive and is just busy with listing, just larger to the harm of human body generation like this.Although there has been output, can not be up to standard because residual, can not walk the gateway of a country, do not enter high-end business and surpass, be difficult to enjoy high price, planting benefit is difficult to have and significantly promotes.To using the understanding of public nuisance-free agricultural chemicals not enough.The current agricultural chemicals affecting vegetables quality is mainly insecticide agricultural chemicals, again based on organophosphorus insecticides in this type of agricultural chemicals, to use in agricultural chemicals 70% be insecticide; In insecticide 70% be organophosphorus insecticides; In organophosphorus insecticides 70% be high poison, severe toxicity, persistent pesticide.Part peasant household think make medicine after the agricultural chemicals that at once takes effect be exactly agricultural chemicals, and minuent, non-harmful biopesticide price is high, effect slow, be waste man power and material, so certain impact also created on the quality of vegetables.The agricultural byproducts that long-term edible residue of pesticide exceed standard, although can not cause acute poisoning, may cause the chronic poisoning of humans and animals, cause the generation of disease, even have influence on the next generation.Since eighties of last century sixties, agriculture large area uses chemical pesticide, although once for China's agricultural brings immeasurable benefit, use chemical pesticides a large amount of for a long time, its hazard residue caused heavy damage to natural ecological environment.Therefore, replace high malicious chemical pesticide by efficient, nontoxic, nuisanceless, free of contamination green plants source pesticide and become not coilable trend.So producing nuisanceless is current optimal selection with environment friendly agricultural.

Summary of the invention

The object of the invention is to propose a kind of good disinsection effect, without pesticide resistance, the drug effect phase long non-harmful Pesticide with Chinese medicinal material that also can promote crop growth.

According to Pesticide with Chinese medicinal material provided by the invention, be made up of the herbal component of following weight proportion: melia extract 10 parts ~ 60 parts, root bark of celastrus angulatus or stem and bark extract 10 parts ~ 60 parts, derris root bark extract 10 parts ~ 60 parts; Chameajasme extract 10 parts ~ 40 parts, reticulate millettia root extract 10 parts ~ 5 part 0, tripterygium root or leaf extract 10 parts ~ 50 parts; Castor-oil plant fruit extract 20 parts ~ 50 parts, radix sophorae extract 20 parts ~ 50 parts; Crotons fruit extract 20 parts ~ 50 parts, Chinese prickly ash fruit bark extract 20 parts ~ 50 parts, tea seed bran extract 20 parts ~ 50 parts, frutus cnidii fruit extract 20 parts ~ 50 parts, RADIX STEMONAE extract 20 parts ~ 50 parts; Described extract refers to the organic solution extracted by ethanol extraction method.

The present invention is from effective component extracting the various Chinese herbal medicines with insecticide active substance, while playing respective desinsection, anthelmintic action by each active component, also by the interaction between each active component, play the enzymic activity, the cytoactive that affect in harmful insect body, pathogen spore in insect bodies is suppressed to produce, destroy insect nervous system, decompose the effect of polypide albumen; Compared with traditional chemical agricultural chemicals, the present invention has following positive effect:

1, desinsection speed is fast, drug effect is long: reach more than 98% to the killing rate of the serial insects such as Phytophthira, shell insects, aleyrodid class, wood louse class, leafhopper class, stinkbug class, thrips class, tetranychid, and long action time, after dispenser, the anti-efficiency of 2-10 days can reach 93%-97%;

2, without pesticide resistance: the present invention all uses plant component, its insecticidal mechanism and chemical pesticide far different, with natural degradation after insect effect or after certain hour, Non-polluted residue-free, therefore can not develop immunity to drugs;

3, can Promoting plant growth: insecticide of the present invention is pure natural medicinal plant, and plant essence wherein provides required nutrition for plant, can be absorbed by plants, make plant leaf surface fertilizer efficiency remarkable, flowers blade light, longer blooming period, obviously promotes plant maturation.

Wherein, in the present invention, the independent role of each traditional Chinese medicinal components is as follows:

China tree: as a kind of plant insecticide be separated from Meliaceae and the branch skin of China tree, there is stomach toxicity, tag and certain Antifeedant Effects.Pests with contact China tree after, nerve center capable of blocking conduction, destroy intestinal tissue and various Chlorogenic Acid and respiratory metabolism, impact is digested and assimilated, and loses the taste function to food, causes insect to grow abnormal and dead with food refusal;

Celastrus angulatus: its root bark of celastrus angulatus and stem skin and leaf powder have good insecticidal action, has the multiple biological actions such as anesthesia, food refusal, poisoning and nail ovum, can make the anesthesia symptoms such as insect survival rate significantly reduces, stop motion, paralysis to insect;

Trifoliate jewelvine: the acetone of trifoliate jewelvine, benzene and ethanol extract show very high action of contace poison to cabbage caterpillar, trailing plants aphid, black peach aphid, citrus aphid and citrus red mite etc., and active ingredient rotenone mainly acts on the electro transfer complex in respiratory chain;

Chameajasme: other Chinese herbal medicine active components are combined in the present invention, plays and suppresses the effect that in insect bodies, pathogen spore produces;

Reticulate millettia: coordinate with China tree and play the effect of kill pests competent cell;

Tripterygium root or leaf: coordinate with trifoliate jewelvine, reticulate millettia, the public rattan A prime produced, noisy goat's horn florigen, all can affect insect midgut esterase active, cause enterocyte thickening and chaotic distortion, cell arrangement is irregular, columnar cell and goblet cell misaligned and have longitudinal muscle and microvillus obscission, finally cause digestive system to damage, polypide is dead;

The tuber of stemona: all have killing action to mosquitos and flies larva, head louse, clothing lice and bedbug etc., alcohol preserved material is large compared with the effect of water logging agent;

Kuh-seng: one of broad spectrum pesticide, has obvious control efficiency to the armyworm on various crop, cabbage caterpillar, aphid, two spotted spider mite;

Frutus cnidii: the feature with high activity, micro-toxicity, noresidue, Osthole suppresses the chitin deposition performance killing pests and suppressing bacteria on insect body wall and fungal cell wall active, pathogen spore also can be suppressed to produce, sprout, stick, invade and germ tube elongation and act on the nervous system of insect.
