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 indohii micromycete biomass with a non polar extracting agent in supercritical 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 |
