METHOD FOR PREPARING INSECTICIDE PREPARATION AND PREPARATION BASED ON MICROORGANISMS BACILLUS THURINGIENSIS Russian patent published in 2005 - IPC

Abstract RU 2264101 C2

FIELD: microbiological industry, microbiology, insecticides.

SUBSTANCE: invention relates to methods for producing agents for plants protection and against harmful insects. Invention proposes a method for preparing insecticide preparation and preparation based on microorganisms Bacillus thuringiensis. Method involves culturing microorganisms Bacillus thuringiensis, isolation of delta-endotoxin from biomass by addition a solvent, removal of precipitate and mixing solution with a filling agent and sticker followed by drying the end product. Insecticide preparation obtained by proposed method comprises the following components, wt.-%: active component - dissolved delta-endotoxin from Bacillus thuringiensis, 10-20%; alkali (NaOH or KOH), 3-8%; reducing agent - β-mercaptoethanol, 1-8%; sticker - a stabilizing agent of working suspension molasses or dry buttermilk, or pectin, or whey, or hydrolyzed chitin, or ground fish glue, or pectin from beet or apple pulp, 3-20%; filling agent, for example, NaCl - up to 100%. Method provides preparing highly effective and rapidly acting insecticide preparation.

EFFECT: improved preparing method, valuable properties of preparation.
