Abstract
A method for integrated protection of hop plantations from harmful arthropods includes settling laboratory cultures of Trichogramma onto plants. In the spring-summer period two techniques of joint settling of two species of Trichogramma, in particular Trichogramma evanescens Westw. and T. pintoi Voeg., onto hop plants are carried out in a ratio of 1:1, with an interval of 6-7 days in an equivalent of 750 and 800 females per 100 mof an agrocenosis. In addition, in the period of the beginning of rebirth of caterpillars and larvae of the pests single spraying of plants with the biopreparation Phytoverm 0.2 % e.c. (emulsion concentrate) is carried out in an equivalent of 1.2 l/ha. In the period of appearance of caterpillars of the elder ages and pupae two joint settlings of laboratory cultures of the entomophages Habrobracon (Habrobracon hebetor Say.) and Dibrachus (Dibrachus cavus Walk.) are carried out with an interval of 5-6 days in a ratio of 1:1, in an equivalent of 60 and 80 females per 100 mof the area of the agrocenosis.
