Preparation method and application of eauveria-spinosad suspending agent

Abstract

The invention relates to a preparation method and application of q beauveria-spinosad suspending agent. Beauveryia bassiana and spinosad are the active ingredients of the suspending agent which is used for preventing and treating agriculture and forestry injurious insects, such as leptinotarsa decemlineata and acridid and the like. The invention is characterized in that (1) the suspending agent comprises active ingredients, namely the beauveryia bassiana and the spinosad; and (2) the mass ratio of the beauveryia bassiana and the spinosad is (30:1)-(30:2), and the mass percent of the effective components in the preparation is 3.1-10%. The preparation method has the advantages that the product can be dissolved with oil or water; the effective duration of the beauveria vuillemin and the relative quick action of spinosad have complementary advantages, and injurious insects of various crops are treated; and the suspending agent prepared by the method has the advantages of good synergism and permeability, strong adhesivity and evaporation resistance and the like.

Description

technical field [0001] The invention relates to a microbial oil suspension, specifically an oil suspension with Beauveria bassiana and spinosad as active ingredients, which is mainly used for the prevention and control of potato beetles, locusts and other pests. Background technique [0002] Beauveria is the most common entomopathogenic fungus, which can infect more than 700 kinds of insects and mites, reproduce in large numbers in the body of the host, change the body fluid discovery function, and cause metabolic disorders and even death. The distribution range of Beauveria bassiana is very wide. Beauveria bassiana has been found in mountains ranging from a few meters above sea level to more than 2000 meters. Beauveria bassiana has strong pathogenicity and is safe for human and animal crops. One of the entomopathogenic fungi. [0003] Beauveria bassiana has long been used by researchers as an important means of pest control because of its wide host range, strong prevalence...

Problems solved by technology

14 kinds of preparation products have been registered in foreign countries, but in practical applications, most of the conidia preparations of Beauveria bassiana still use solid preparations such as powders, which have low content of active ingredients and large volume, which poses problems for transportation, storage and use. It is very difficult; and due to the hydrophobicity of the Beauveria bassiana conidia, the amount of bacterial powder used in use is large, the adhesion is not good, and the control effect is very unstable.
