METHOD FOR PREVENTING FROM SETTLING BERRY-FIELDS WITH STEM PHYTOPHAGES

摘要

A method for preventing from settling berry-fields with stem phytophages includes a visual monitoring of a species composition of the phytophages. At the beginning of egg laying of females of the currant borer moth and Agrilus viridis var. fagi Ratz. and in the period of the beginning of rebirth of caterpillars of the the currant borer moth and larvae of Agrilus viridis var. fagi Ratz. two overall sprayings of the berry-fields plantations are carried out with a composition based on an aqueous solution of wormhole dust, which is procured by means of dissecting branches of the berry-fields of not elder than one year and taking out the core therefrom, in particular excrements as a result of feeding caterpillars and larvae of stem phytophages. A consumtion rate of the composition is 2.0 l/ha.
