METHOD TO CONTROL SPREADING AND HARMFULNESS OF PATHOGEN OF CURRANT POWDERY MILDEW (SPHAEROTHECA MORS-UVAE BERT.ET CURT.)

摘要

A method to control spreading and harmfulness of the pathogen of the black currant powdery mildew includes use of chemical fungicides. In spring, prior to flowering, single spraying of plants with an aqueous solution of the preparation Topsyn-M is carried out. In 14-15 days single spraying of plants with an aqueous solution of the preparation Topaz 100 EC is carried out. In the period of the beginning of flowering and in 6-8 days two settlings of the predaceous mite Amblyseius finlandicus onto bushes are carried out. Soon after flowering two sprayings of plants with an aqueous solution of the biological preparation Ampelomycin are carried out.
