Abstract
The present invention relates to insecticide emulsifiable solution preparation. The present invention is characterized in that the emulsifiable solution preparation comprises components measured by wt%: 5 to 50 wt% of neem oil, 0.1 to 2 wt% of abamectin, 5 to 15 wt% of surface active agents, 2 wt% of stabilizing agents, 0.5 to 5.0 wt% of 6-butylated hydroxytoluene, 1 to 2.5 wt% of sunscreen agents, and organic solvent as the rest. The present invention has obvious synergistic effect on killing pests because of recompounding the neem oil and the abamectin, simultaneously has the advantages of high efficiency, low toxicity, low residue, no pollution for agricultural products and environment, wide disinsection spectra, etc., and has better preventing and curing effect on various pests. The insecticide emulsifiable solution preparation can be used as insecticide.
Description
Technical field: the present invention relates to formulation of pesticide and preparation technique.
Background technology: the seal chinaberry is one and originates in the living arbor of speed that Burma and India are subordinate to Meliaceae, now be distributed widely in Africa, Madagascar, gross profit ask this, Indonesia, Thailand, Australia, Caribbean South America and Central America.It is successful that China introduced a fine variety the seal chinaberry from African Togo in 1986, and recent years, the seal chinaberry is developed rapidly in Yunnan and Hainan Province.The neem oil that obtains by cold rolling lixiviate removes and includes glyceride (80-95%), outside free fatty acid (4-20%) and small amounts of inorganic and the organic salt, also contain pesticide and miticide actility composition such as nimbin and multiple bitter principle etc., according to international latest report, these active ingredients can be prevented and treated 413 kinds of insects.Its mechanism of action is different from the chemical pesticide of conventional organic synthesis.Seal chinaberry compound is by food refusal, walks quickly and keeps away, stop the children (if) worm casts off a skin and grows, walks quickly and keeps away and reduces the adult egg laying amount, also there are certain tagging, stomach toxicity and ovicidal action the while.The same with mineral oil with other vegetable oil, neem oil also has the effect that insect and mite class pore make insect be choked to death of stopping up.
Avermectin (Abamectin) is a kind of antibiotics Insecticidal and acaricidal agent through explained hereafter such as microbial fermentation refinement and electronations.Main by of the release of stimulation polypide with reinforcing gamma-amino butyric acid, thus the transmittance process of blocking-up kinesitherapy nerve signal reaches the neurophysiology activity of disturbing insect.Paralysis symptom occurs when insect contacts Avermectin with the mite class, inertia is not got food and death gradually.Avermectin is degraded at plant leaf surface, but but infiltrates active substance long period in the plant tissue and be present in the plant tissue and conduction is arranged.Therefore, Avermectin is a biopesticide, has been widely applied at present in insect (mite) control on the pollution-free food.But a large amount of and frequent use of its single agent exists the danger that insect (mite) develops immunity to drugs.The composite advantage that can change its public nuisance-free agricultural chemicals with chemical pesticide.
Though abroad contain the complex preparation registration of nimbin, nimbin and other agricultural chemicals used many reports with.Registered nearly ten of China is main active ingredient or the complex preparation that contains nimbin with nimbin.But both there be not the patent application report in China, yet product-free registration with this single agent of neem oil as insecticide.The compounded pesticides that contains neem oil and Avermectin had not both had patent report in the world, yet product-free registration.
Though many seal chinaberry equipment registration registrations are arranged in the world, have many effects limit the practical application aborning of these products.As the active ingredient of neem extract such as nimbin and bitter principle under illumination condition, acid-base value is not suitable for and easily decomposes when meeting crop blade face compound, be subjected to the very fast loss of rain drop erosion active ingredient, medicine itself can not effectively penetrate the insect surfaces wax coat or can not be lost to the loss that causes active ingredient in the soil at the abundant spread of crop surface.
Summary of the invention: the objective of the invention is to overcome the deficiency of prior art, a kind of new neem oil and the compounded pesticides of Avermectin are provided.Insecticide of the present invention has significant synergies to insect, and efficient, low toxicity, low-residual do not pollute agricultural product and environment, and insecticidal spectrum are wide.
Technical solution of the present invention is, is main active ingredient with neem oil and microbial pesticide-Avermectin, and is re-dubbed formulation of insecticides by the special auxiliary agent of suitable prescription adding.The inventor finds that first remarkable synergistic effect is arranged between neem oil and the Avermectin when preventing and treating the various agricultural insect.Toxicity Determination shows, when insects such as control Trialeurodes vaporariorum Westwood and spider mite kind synergistic effect particularly remarkable, its co-toxicity coefficient is greater than 300.Than using single agent, significantly reduced dosage.By technical solution of the present invention, can finish purpose of the present invention.
Before formulated, at first (obtain by method for cold pressing to neem oil, temperature is no more than 40-45 ℃) a certain amount of nimbin of middle adding, make it reach the nimbin content of standard-required, add the former medicine and the auxiliary agent of Avermectin then by the proper formula ormal weight, utilize suitable processing technology to make stable neem oil abamectin emulsifiable concentrate.
The feature of emulsifiable formulation preparation of insecticide of the present invention is that said cream preparation composition (in weight %) is: neem oil 5-50, Avermectin 0.1-2, surfactant 5-15, stabilizing agent 2,6 BHT 0.5-5.0, sun-screening agent 1-2.5, surplus is an organic solvent.
Said surface active agent composition is to be selected from one or more of sorbitol ester, soil temperature, neopelex, and the sun-screening agent component is to be selected from a kind of in p-aminobenzoic acid, the castor oil, and the organic solvent component is to be selected from benzene, the dimethylbenzene any.
The preferential emulsifiable formulation preparation of insecticide composition of recommending (in weight %) is: neem oil 20-50, and Avermectin 0.1-1.0, surfactant 5-10, sun-screening agent 1-2.5, stabilizing agent 0.5-5.0, surplus is an organic solvent.
Neem oil abamectin emulsifiable concentrate preparation adopts conventional pesticide cream preparation processing technology to get final product in preparation process.
Compare with prior art, the present invention has following advantage and good effect:
1, both are composite has significant synergies to insect.
2, efficient, low toxicity, low-residual do not pollute agricultural product and environment.
3, insecticidal spectrum is wide, and various pests is all had good control efficiency.
Embodiment: use the nimbin of different content allocation plan and Avermectin and other auxiliary agent the Trialeurodes vaporariorum Westwoods of the vegetables of causing harm, apple tetranychus etc. have been carried out indoor virulence screening test and field biological effect small plot experiment.
