Unele aspecte despre entităţile parazite care produc rugina părului în Republica Moldova

Abstract

The article presents the scientific results about the composition, morphology and biology of the parasitic flora entities that cause to pear disease (Pyrus), by developing the pathogenic agent Gymnosporangium sabinae. We present the results of the biological effectiveness testing of new fungicides such as Manific, WP and Cimus Progress EC against this pathogen. The experimental results demonstrated that the biological effectiveness of Manific, WP against the G.sabinae pathogen was relatively low. Higher biological efficiency was established for the Cimus Progress EC triazole preparation. On the basis of the results obtained, it is proposed to officially test Manific, WP and Cimus Progress EC as fungicides against G. sabinae for inclusion in the integrated pest management system of the pear plantations.
