METHOD FOR MANUFACTURING ACARICIDE-INSECTICIDE COMPOSITION Russian patent published in 2004 - IPC

FIELD: biotechnology, plant protection. SUBSTANCE: the present innovation deals with manufacturing special preparations for plant protection against harmful insects and ticks. Nematodes' suspension of Steinernema sp. Should be mixed with an antidesiccant obtained due to successive extracting Mortierella nigrescens micromycete biomass with extragent in supracritical state with water, alkali, water, acid, water, alkali and water followed by combining the first extract with solid residue. Antidesiccant should be introduced into suspension of entomopathogenic nematodes at the quantity of 0.2-1% against composition weight. The method enables to shorten the expenditure of nematodes due to the increase of their survival rate in the composition suggested. EFFECT: higher efficiency. 1 tbl
