Abstract
The invention belongs to the field of pesticides, specifically involves a rotenone compound insecticide and its preparation method. In the invention, the active ingredient of rotenone and capsaicin is selected, prepared and mixed or on this basis other insecticidal active ingredient is added in and mixed, then high-efficient, low-toxic plant-pesticide is got. In the application the ingredients in this pesticide of the invention play cooperatively, improve the effectiveness of the use of pharmaceutical product, and have good kill effect on plutella xylostella, pieris rapae, aphids, red spider, and so on.
Description
Technical field
The invention belongs to field of pesticides, be specifically related to a kind of rotenone mixed insecticide and preparation method thereof.
Background technology
Along with the reinforcement of people's environmental consciousness, be wide spectrum, efficient, low toxicity, easily degraded, little to surrounding environment influence to the requirement of insecticide.Insecticide main source commonly used at present is chemosynthesis, though insect is had good control efficiency, toxicity is bigger mostly, easily cause the person poultry poisoning, big for environment pollution, and a large amount of kill pests natural enemy, and insect can produce drug resistance to this after long-time the use.
Rotenone is a kind of a kind of insecticide active substance that extracts from Derris trifoliate jewelvine section liane, chemical name is 2R-(2 α, 6a α, 12a α)] 12a-tetrahydrochysene-8-1,2.12,, 9-dimethoxy-2-(1-methyl ethylene)-[I]-chromene [3,4-b]-furans also-[2,3-h] [1]-chromenes-6 (6aH)-ketone, insect is played action of contace poison and stomach poison function.Enter growing of interference cell behind the polypide, make it hypopnea, polypide can not get the energy supply, drumble death.Rotenone is oxidation easily in air, to biology and environmental influence are little on every side, is a kind of relatively vegetable insecticide of safety.Existing rotenone suspending agent [Huang Jiguang etc., rotenone suspending agent and preparation method thereof, CN 1513314A], the mixture preparation of rotenone and other insecticides, comprise rotenone and Avermectin, rotenone and Bt, rotenone and anabasine [Xu Hanhong etc., the mixture preparation of rotenone, CN 1309910A].The insecticidal spectrum of rotenone is wide, but exists effective desinsection concentration higher in application, the high deficiency of use cost.
Capsaicine (Capsaicine) is a kind of alkaloid that extracts from capsicum, and chemical name is a N-[(4-hydroxy 3-methoxybenzene base)]-8-methyl-(instead)-6-nonene acid amides.Capsaicine is mainly used in medical research and tear-gas weapon production at present.
Recent study shows that capsaicine is fat-soluble stronger, and stronger Transdermal absorption effect is arranged, and with the capsaicine receptors bind on the neuron membrane, promotes cationic entering such as calcium or sodium ion, the impulsion of block nerves cell.Capsaicine has begun a kind of [Zhang Jingbin, a kind of capsaicin composite pesticide, the CN 1435093A] as agricultural chemical insecticide
It is composite or based on rotenone, the composite mixed insecticide of capsaicine to yet there are no rotenone and capsaicine.
