FIELD: biotechnology. SUBSTANCE: first, (0.5- 0.6):1 mixture of nematode biomass with colloidal solution of sodium alginate cooled to 6.0-8.0 C is prepared. To homogeneous mass, soluble silicon dioxide powder is portionwise added at stirring to form easily pulverized mass in which indicated components are contained at ratio 1:(0.2-0.4) and content of ready-to-use nematodes is 200-250 thousand species per 1 g. Preparation is then placed in moisture-proof packaging. EFFECT: preparation is easy to use, increased vital activity of nematodes, and enhanced insecticide activity with regard to pest larvae.
