The ecologically secure system of cabbage protection against Lepidoptera pest complex with maximal using of biological preparation of protection – inhibitors of hitin synthesis (Nomolt, Dimilin), microbiopreparation (Lepidocid) and trichogramma – is represented. The system consists of three technologies of successive using of biological preparations in dependence on dominant pests in agrocenosis, climatic conditions and potentials of producent. As a result of the lead researches three technologies of use of means of protection depending on number of dominating wreckers in agrocoenosis, climatic conditions and opportunities of producent are developed and approved. The first technology is recommended to be applied at high number of the first generation cabbage moth, the first generation of a complex of scoop, white butterfly and favorable for trichogramm releases, weather conditions during development of the second generation of wreckers (a scoop). The second - at high number of the first generation cabbage moth, the first generation white butterflies and low number of the first generation of a scoops complex and also under favorable weather conditions for trichogramm releases during development of the second generation of wreckers (a complex of scoops). Third - at favorable for trichogramm conditions and agrocoenosis where in the beginning of the vegetative period the scoops and turnip white butterfly, and in the second generation - cabbage white butterfly prevail
