Abstract
The invention relates to an insect virus and beauveria bassiana mixing insecticide suspending agent and a preparation method thereof. Beauveria bassiana and insect viruses are mixed, so that the insecticidal spectrum is expanded, and the insecticide capacity is improved; mixing of the beauveria bassiana and the insect viruses can achieve a synergism effect; furthermore, by adding of a high-activity organic silicon surfactant and combination of a small quantity of insect epicutile chitin suppressing agents, the surface tension of the preparation is reduced, and the interface performance is changed, so that the drug and the body wall of an insect can be well affined, and the drug can quickly enter the insect body; therefore, the infection rate of the insect viruses and the beauveria bassiana is greatly increased, and the fast-acting property and the insecticidal activity of the drug are greatly improved; and meanwhile, by adding of an adsorbent, a light protecting agent, an antioxidant and the like, spores and virus particles are effectively protected; the shelf life is prolonged, and requirements of agricultural production and sanitation and insect prevention and treatment of forests and steppes are met.
Description
Technical field
The present invention relates to technical field of insecticide, particularly relate to
oneplant insecticidal suspending agent of insect viruses and white muscardine fungi mixing and preparation method thereof.
Background technology
The use of chemical pesticide causes a large amount of pollutions, such as water pollutions, soil pollution, air pollution etc.What these were serious has threatened the life and health of people, result in the generation of a large amount of malignant diseases as tumour.Moreover, peasant in order to unilateral pursuit control efficiency, often overdose, heavy dose of use agricultural chemicals.The resistance that this unscientific application method result in a large amount of chemical pesticides occurs.
Biopesticide is thought to solve the dysgenic important means of chemical pesticide widely, more and more comes into one's own.Biopesticide is divided three classes: bacteria type, fungi type and virus type.Wherein, white muscardine fungi is the important representative of the biological insecticides of fungi type, and white muscardine fungi is a kind of entomogenous fungi of Fungi Imperfecti.Amount reproduction in the polypide that white muscardine fungi can invade 200 various insects, mite class, constantly produce white stiff element (large ring grease toxoid) and calcium oxalate crystal simultaneously, these materials can cause insect poisoning, and body fluid is found, and function changes, and upset metabolic so that dead.At patent of invention publication number CN101099490A, " in a kind of white muscardine fungi insecticidal suspending agent and preparation method thereof ", disclose technique prepared by white muscardine fungi suspending agent, although the wide spectrum of white muscardine fungi desinsection, but the control efficiency of white muscardine fungi is unsatisfactory in some insect pest and crop, and be subject to various factors, first, the environmental benefits of high humidity is in the sprouting of beauveria bassiana spore, the environment of low humidity is then contrary, secondly, insect host polypide valetudinarian, invalid is conducive to the infection of white muscardine fungi, and the strong person of polypide is then contrary.
In order to improve the control efficiency of white muscardine fungi, patent of invention CN200810220002.6 " a kind of beauveria bassiana and destruxins lethane and preparation method " proposes and white muscardine fungi and green muscardine fungus are carried out mixture improves insecticidal effect.But its limitation is, white muscardine fungi and green muscardine fungus belong to Mycophyta insecticide together, complementary fit limited advantages.The open CN201410084227.9 of patent " a kind of Archon beauveria bassiana and bacillus thuringiensis,Bt. multiple killing teichomycin composition " propose the mixture of bacillus thuringiensis,Bt and white muscardine fungi to improve drug effect in patent.But its limitation is that the amplification of bacillus thuringiensis,Bt originally in polypide is limited in one's ability, Zeng Rui is periodical " Tropical Forest " nineteen ninety-five 23 volume 116-119 page " forest farm, Chengmai application white muscardine fungi, pine caterpillars is analyzed in polyhedrosis virus control ", compare the effect utilizing white muscardine fungi and polyhedrosis virus control pine caterpillars, wherein there is susceptible symptom the 10th day larva in Masscn Pine Caserpillar Control with Beauveria bassiana, morbidity in 25th day, there is bombys batryticatus, preventive effect is about 55%, high to environmental requirement, drug effect is slow, not good to the preventive effect of large instar, but white muscardine fungi low price, production procedure is simple, on the other hand, polyhedrosis virus is not strict to environmental requirement, only require that temperature is more than 25 DEG C, spray under avoiding sunlight, drug effect is obvious, preventive effect can reach about 70%, and within 3 days, occur infecting death, mortality in 6-8 days, within 10-15 days, there is peak mortality, obvious to large instar preventive effect, but due to the limitation of technology, " forest farm, Chengmai application white muscardine fungi, pine caterpillars is analyzed in polyhedrosis virus control " in that white muscardine fungi is not mixed with virus, and the formulation used is that effect is poor, prepare original pulvis, the form formula of an efficient science is not provided, formulation has significant impact for the effect of the medicament of biopesticide, suspending agent is the formulation of a kind of advanced person, suspending agent refers to the preparation be scattered in by the particulate homogenous under former for the pesticide granules of solid medicine 4 microns in water, the problem of the dust from flying that suspending agent does not have wetting powder such, be not easy blast, particle is little, biologically active is high, than great, packaging volume is less, relative to other formulations of pesticide safety and environmental protection, and often add various auxiliary agent in suspending agent, greatly improve the result of use of pesticide original medicine, lasting effect, and stability.
Very high interfacial tension is there is between the close ester crust of insect and the medicament being watered use; make medicament be difficult to insect and plant surface affine; irrational preparation; not only can cause the inactivation of part biological body; and the performance of its effect can be reduced greatly; thus affect quick-acting and overall control efficiency; the material that organism can be protected to injure from various stress factors is added in formulation; prepare light to stablize; strong stress resistance, the novel form that practical effect is good is key prepared by biological agricultural chemical insecticide preparation.
