METHOD FOR LONG-TERM CONSTRAINING OF HARMFULNESS OF POPULATIONS OF GALL-MIDGE THOMASINIANA RIBIS MARIK.

摘要

A method for long-term constraining harmfulness of populations of the gall-midge Thomasiniana ribis Marik. includes using insecticides of chemical and biological origin. At the amount of the gall-midge exceeding two and more threshold levels in the period of mass egg-laying of females of the gall-midge single spraying of plants with an aqueous solution of the preparation Aktara 25 WG (water-soluble granules) is carried out. In the period of migration of larvae of the gall-midge of the first generation for pupation single treatment of soil surface and plant residues with an aqueous solution of the preparation Pecylomin is carried out.
