METHOD FOR BIOLOGICAL CONTROL OF PHYTOPHAGES OF BERRY-FIELD PLANTATIONS

摘要

A method for biological control of phytophages of berry-field plantations includes monitoring of species composition of the phytophages and directed action on certain stages of development thereof. In the period of the spring reactivation of a complex of sucking and lepidopterous harmful species, mites and insects singe spraying of bushes of the berry fields with the biological preparations Biostat e.c. (an emulsion concentrate) is carried out with a consumption rate of 0.5 l/ha. In addition, in the period of the beginning of mass egg-laying of the fruit-tree leaf roller rose (rchips rosana Z.) in midsummer and Exapate congelatella l. in autumn double settling of the Trichogramma (Trichogramma pintoi Voeg.) is carried out in an equivalent of 50 and 70 females per one bush correspondingly. Furthermore, once manifesting the signs of the disease by the pathogen of the American powdery mildew began, single treatment of bushes with the biological preparation Bactophyt is carried out in an equivalent of 6 l/ha.
