Abstract
The present invention relates to a new-type beauveria bassiana pesticide suspension. Its composition includes (by wt%) 1-50% of beauveria bassiana powder, 0.05-15% of chitin inhibitor, 0.25-40% of organic silicon surfactant, 0-40% of adsorbing agent, 0-20% of dispersing agent, 0-20% of moistening agent, 0-20% of antioxidant, 0-20% of photoprotection agent, 0-20% of viscosifier and 1-60% of water. Said invention also provides the concrete steps of its preparation method, and its concrete application method.
Description
Technical field
The present invention relates to a kind of novel beauvericin insecticide suspending agent and preparation method thereof.
Background technology
Along with the development of economic society and the raising of people's living standard, the research of fungus insecticide and use are subjected to increasing attention.China is as fungus insecticide producing country the biggest in the world and use state, obtaining bigger progress aspect the industrialization of fungus insecticide in recent years, but product quality problem highlights thereupon.Fungi is mainly invaded insect by body wall, thereby has the unrivaled unique superiority of other insect cause of disease.Yet fungi also has distinct disadvantage such as insecticidal effect is slow, affected by environment greatly, effect instability.Therefore, on purpose carry out genetic improvement, obtain efficient engineering bacteria and development high activity novel form is the main method that addresses the above problem producing bacterial strain at these problems.The body wall of insect mainly is made up of albumen substrate and distribution chitin wherein, insect pathogenic fungus is changeable structure in order to penetrate this complexity, infect the position at it and will secrete a series of different body wall digestive enzymes, comprise protease, chitinase, esterase, lipase etc.Fungi is after invading the insect haemocoele, the parcel of escaping host's haemocyte and the sterilization defense reaction of phagocytosis and antibacterial peptide must take some countermeasures, progress in recent years shows that wherein the gene of encoding proteins enzyme and chitinase is the key gene of decision insecticidal toxicity; Might the artificial insecticide efficiency that improves the insect pathogenic fungus bacterial strain by gene engineering method.
Meanwhile, the preparation performance of fungi bactericide also is the key factor that influences pharmacy effect.Insect parent ester epidermis and convert between the medicament that water uses and exist very high interfacial tension, it is affine that medicament is difficult to insect and plant surface.Irrational preparation not only can cause death of part thalline or inactivation, and can will reduce its effect performance greatly, thereby influences quick-acting and whole control efficiency.Add in formulation and can protect spore to avoid various materials of coercing factor injury, preparation light is stable, strong stress resistance, novel form that practical effect is good are the keys of fungus insecticide formulation preparation.
We reduce the preparation interfacial tension by the combination of high activity organic silicon surfactant and a small amount of insect cuticle chitin inhibitor, change the preparation interface performance, thereby make medicament and insect body wall well affine, and make medicament enter in the pest body rapidly, the result significantly promotes fungal infection speed, improves the quick-acting and the insecticidal activity of medicament greatly.By the adding of auxiliary agents such as adsorbent, bright protective agent, antioxidant, protect spore effectively simultaneously, prolong its shelf life, satisfy the needs of agricultural production and health, forest, grassland control of insect.
Summary of the invention
The invention provides a kind of novel white muscardine fungi (Beauveria bassiana) insecticide suspending agent and preparation method thereof.It is poor that this beauvericin insecticide suspending agent has overcome microbial pesticide quick-acting, shortcomings such as effect instability, have quick-acting, high activity, good stability, the easy advantage of preservation and convenient transportation.
Technical scheme of the present invention is as follows:
This beauvericin insecticide suspending agent is characterised in that and comprises former powder of white muscardine fungi and following auxiliary agent that described auxiliary agent comprises chitin inhibitor, organic silicon surfactant, adsorbent, dispersant, wetting agent, bright protective agent, antioxidant, tackifier and water; The weight portion proportioning of described each component is as follows:
