METHOD FOR PROTECTING PERENNIAL PLANTATIONS AGAINST QUARANTINE PHYTOPHAGE SPECIES

摘要

A method for protecting perennial plantations against quarantine species of phytophages includes use of biological preparations for protecting plantations. In the period of mass egg laying of females of phytophages double settling of laboratory cultures of Trichogramma, the Trichogramma dendrolimi Mats. species, onto trees is carried out with an interval of 6-8 days in an equivalent of 80 and 100 females per one tree. In the period of beginning and mass rebirth of caterpillars of the phytophages double spraying of the trees is carried out with an aqueous solution of the preparations Viryn ABB 0.3 l/ha and Lepidocide c.p. (concentrated powder) in an equivalent of 2.0 kg/ha. In the period of appearance of caterpillars of phytophages of elder ages on trees double settling of the ectoparasite Habrobracon, the species Habrobracon hebetor Say., onto trees is carried out in an equivalent of 25 and 30 individuals per tree.
