Phyto-pesticide and use method thereof

The invention discloses a phyto-pesticide and a use method thereof. The pesticide is used for controlling aphids, rice planthoppers and cabbage worms. A principle of 'monarch, minister, adjuvant and messenger' for drug formula in philosophy of the traditional Chinese medicament is used in the development of a product of the phyto-pesticide formula. The phyto-pesticide comprises four plant extracts including 0.5 to 10 percent by sanguinarine of macleaya cordata, which plays a main insect killing role and serves as a monarch drug; 2 to 20 percent by nicotinamide of tobacco extract, which is used for improving the insect killing effect of the 'monarch drug' and serves as a 'minister drug'; 5 to 10 percent by teasaponin of tea oil cake, which is used for making a target insect refuse to have food, generates certain gastrointestinal toxicity to reduce the viability of the insect and serves as an 'adjuvant drug'; 0.1 to 0.5 percent by natural borneol(L(-)-Borneol ) of borneol camphor, which can expel the insect and serves as a 'messenger drug'. The formula combines the 'monarch, minister, adjuvant and messenger' composite formula and an additive and a carrier to prepare the pesticide with insect expelling effect. The phyto-pesticide is effective, free from residue and environmentally-friendly.

ActiveCN101849994AAddress process complexitySolve the large consumption of solventPlant ingredientsActivated carbonAlcohol
The invention relates to a preparation method of macleaya cordata extracts, which comprises the following steps: carrying out diacolation on macleaya cordata medical materials by an acid solution; adding alkali into diacolation liquid for regulating the solution to the alkaline solution for carrying out alkali deposition; dissolving precipitates by low-carbon alcohol; adding a proper amount of active carbon for back flowing extraction; adding acid for generating salt after the recovery of partial solvents from extraction liquid, and separating out orange crystalline precipitates; filtering the precipitates; using alcohol to wash remained acid; and obtaining the macleaya cordata extracts after drying. The extracts have the main ingredients of benzophen anthridine alkaloid salt with sanguinarine and chelerythrine as the representatives, and the total content is not lower than 60 percent through being metered by raw alkali, wherein the content of the sanguinarine is not lower than 40 percent, and the content of the chelerythrine is not lower than 18 percent. The preparation of the macleaya cordata extracts of the invention has the advantages of simple method and equipment, stable process, short production period and little environment pollution. The obtained extracts have high yield, low cost and stable product quality.

Sanguinarine alcoholate and chelerythrine alcoholate and preparation method and application thereof in animal acaricidal drugs

The invention relates to a sanguinarine alcoholate and a chelerythrine alcoholate and a preparation method and application thereof in acaricidal drugs for animals. Livestock and poultry acariasis is an in vitro parasitic disease which can cause serious damage to the animal health, and serious stress response of animals to influence ingestion, feed efficiency and weight gain, even cause death. At present, the control of the animal acariasis mainly relies on drugs for killing ticks and mites, and the ticks and mites can produce resistance to the drugs after the drugs are used for a long time, so that the drugs can cause adverse environmental and ecological effects, and can only drive and kill polypides instead of ova. The sanguinarine alcoholate and the chelerythrine alcoholate are derived from natural compounds-sanguinarine and chelerythrine alcoholate, and exist in the form of free alkaloids in the acaricidal drugs for animals. The sanguinarine alcoholate and the chelerythrine alcoholate have the characteristics of low toxicity, low residue and not easy production of resistance to the drugs of natural drugs, and have remarkable acaricidal activity and good treatment effect on the acariasis of animals when the sanguinarine alcoholate and the chelerythrine alcoholate are applied as the acaricidal drugs for animals.
