Microbiological and bacterial diseases of apple fruits during storage

Abstract

During storage, fruits are affected by a complex of pathogens, from which one pathogen of bacterial origin and 11 of fungal etiology have been isolated. It was determined that the treatment of apple fruits before dispatch for storage with fungicides with the following rates of application: Luna Tranquillity, SC –1.0 l/ha, Geox, WDG–0.4 kg /ha, Zato, WDG–0.15 kg /ha allows to save up to 98% of the crop yield. At the same time, the waste contained fruits with mechanical damage affected by the mold fungus Penicillium roseum LK. Biological efficacy of Luna Tranquillity, SC, Zato, WSG and combinations of these fungicides against Penicillum roseum LK. were at the level of 81-95%, no other diseases were detected in these variants. It was found that fungi were found on fruits treated with a combination of fungicides Topsin - M, WP–1.5 kg/ha in combination with Merpan, WP–2.5 kg/ha and Medea preparation, ME–1.0 l/ha; such fungi were Fusarium avenaceum (fr.) Sacc, Gloeosporium fructigenum Berk, Penicillum roseum LK.
