Background technology
At present, the annual expense of pest control with insecticide agent to preventing and controlling pest of using in the whole world is up to 10,000,000,000 dollars, and even so, the loss that annual insect pest causes still accounts for 20-30 % of total output of crops.But, because the long-term chemical pesticide that uses brings environmental pollution and person poultry poisoning, the series of problems such as sick worm pesticide resistance raising, some countries have started chemical pesticide to take to limit the use of and forbidding measure.Particularly 1992, world environments proposes " will control in the world sales volume and the use of chemical pesticide, the output of biopesticide in 2000 should account for 60 % of agricultural chemicals total amount " with development conference, and afterwards, each state all strengthened development and the exploitation of biopesticide.
The research and development of pure natural plant source pesticide becomes emphasis and the focus of world gradually.Since 20 century 70s, countries in the world government has started to pay attention to research, safe, harmless, efficient, the multi-functional botanical pesticide of development and application.According to the literature: the countries in the world scientist desinsection to 2000 various plants, mildew-resistant, weeding and growth promotion bioactive ingredients is studied, and being wherein no lack of is traditional Chinese herbal medicine.These Chinese herbal medicines mainly comprise: Meliaceae (printing chinaberry, melia toosendan), composite family (Dalmatian chrysanthemum), pulse family (trifoliate jewelvine, Sophora alopecuroide), Ericaceae (Azalea pontica), Celastraceae (thunder godvine), Thymelaeceae (root of langdu), Labiatae (aldehydes matter), Lauraceae (camphor tree) etc.
So far, there is portioned product listing.As Dutch Ropapharm B. V. I. O. with Orv oil and thyme wet goods vegetable oil by the composite preparation that obtains, be used for killing the sanitary insect pest such as plant pest and mosquito, fly effect highly significant, and this medicine is better than taking lindane as basic chemical insecticide, humans and animals is not had to toxic and side effect, be subject to the welcome of countries in the world, in the registered use of China." Frontline " botanical pesticide preparation of Germany's plant pesticide exploitation, the insect-piebald worm strong and crushing large to pesticide resistance in vegetables, has desirable control efficiency.
Botanical pesticide exploitation both at home and abroad is is mainly researched and developed from two innovation focuses:
The one, from traditional vegetable drug, extract desinsection, fungicidal activity position (composition), as host, be mixed with non-harmful agricultural chemicals.Studying many plants has: composite family, Meliaceae, Celastraceae, Ericaceae, Thymelaeceae and mineral humic acid etc.As proposed pyrethrins, isolate nicotine from tobacco leaf, isolate stemonine etc. from the tuber of stemona from composite family.At present, China's botanical pesticide insecticide registered and that produce has: nicotine, galic essential oil, rotenone, pyrethrins, stemonine, chinaberry element, return artemisin, jervine, camptothecine and humic acid with and approximately kind more than 30 of derivative;
