FIELD: agricultural and forest plants. SUBSTANCE: preparative form of water- soluble elemental sulfur for protection of crops from pests comprises aqueous solution of calcium polysulfides. As stabilizer, preparative form further comprises water- soluble low molecular polyethers, and as prolonged action additive, it comprises water-soluble nonionic film- forming and surface active polymers, ratios of components in preparative form solution being as follows, wt %: calcium polysulfides, 0.01-0.1; low molecular polyalcohols, 0.05-0.1; water-soluble polymers, 0.1-1; and the water balance. EFFECT: highly efficient preparative form of water-soluble elemental sulfur. 1 tbl
