The information on micoinsecticidal preparations is presented. The characteristics of two basic methods of mass fungal preparation production in different modifications and the scheme of production is given. The advantages of every methods are shown and it is marked that the technology of a biological preparation production should be developed in conformity with plant protection and a certain complex of noxious phytophages.The batch method is highly productive and enables to use various organic substrata including industrial and agricultural waste. At the same time this method has also essential lacks connected with difficulties with material sterilization, long time of cultivation and labour input of fungi propagula separation from a nutritious substratum. Two-stage technology is considerably less productive however essentially reduces time of manufacture and the fungi material is easily separated from a nutritious substratum that does possible the creation of preparative forms creation suitable for little volume of plants sprayings. It is rather essential also that at two-stage technology fungi form technologies both conidium and blastospore. It can strength the influence of fungi on target object
