The Andes in America, introduces a fine variety India in 1882, and nineteen twenty-two introduces a fine variety Thailand as spice berry, is now distributed widely in
South America, Asia, torrid areas, Africa.Within 1934, find first in Yunnan Province of China south, present China Taiwan, Guangdong, perfume (or spice)
There is distribution on the ground such as port, Macao, Hainan, Guangxi, Yunnan and Guizhou.Herba Eupatorii Odorati belongs to instruction plant in China, can invade canopy density relatively
Low pure forest, such as eucalyptus globulus woods, rubber forest etc., the most extensively invades various herbage field, to agriculture-stock production on the ground such as Yunnan, Hainan
Tremendous economic is caused to lose.When its plant height reaches 15cm or higher, other herbal lifes just can be affected significantly
Long, except the fertilizer that wins honour for other plant, strives, strive water in addition to, moreover it is possible to produce allelochemical, the growth of the neighbouring plant of suppression.Herba Eupatorii Odorati
Leaf is poisonous, containing coumarin, wipes skin with it and can cause redness, foaming, eat tender leaf by mistake and can cause dizziness, vomiting, also cause
Domestic animal and Fish poisoning, cause insect antifeedant.The preventing and treating of this instruction plant was once studied in international Herba Eupatorii Odorati Biological control management meeting
Work, but there is presently no good control method.In recent years, Herba Eupatorii Odorati has been carried out not in terms of the exploitation of botanical pesticide
Few research, has been reported that its extract of proposition has good Oviposition Repellent of Alcohol Extracts and parasite killing, antibacterial, activity of weeding to insect, but
It is that the effective pesticide of environmental protection that main component is studied there is presently no relevant report with regard to Herba Eupatorii Odorati extract.
In recent years, due to the people's unreasonable use to chemical pesticide and the inherent defect such as insecticidal spectrum of medicament itself thereof
Single, it is used for multiple times and is easily generated Drug resistance, medicine component toxicity is the strongest, and it is a series of that these make pesticide in use create
Pollution problem, such as environmental pollution, person poultry poisoning, killing natural enemy, destroy ecological balance, " 3R " (Residue, Resistance,
The serious problems such as Resurgence), these harmful effects have caused the common concern of people.In recent years on pesticide market, domestic
Insecticide is sold and is glided always, mainly can not show a candle to the preventive effect of external insecticide because of its preventive effect controlling insect pest.And develop in China
