Disclosed is a coated pesticidal agent containing the core with pesticidal agent, surrounded by the matrix comprising 2 to 25 wt. % of pH-dependent polymer, 0 to 5 wt. % of softener, 5 to 46 wt. % of ultra-violet protector, 0 to 75 wt. % of stilbene compound, 0 to 10 wt. % of disintegration agent and 0 to 10 wt. % of sliding agent. The production method of the said agent, wherein the mixture of pH-dependent polymer, pesticidal agent, such as insecticidal pathogen, eventually softener, ultra-violet protector, eventually stilbene compound, eventually disintegration agent and eventually sliding agent is mixed in the organic solvent, such as acetone, C1-C3 alcohol or their combination, with the producing the homogeneous suspension, which is dried, eventually ground.
