Анализ 19 штаммов фитопатогенных бактерий Pseudomonas syringae pv. syringae, выделенных в четырех областях Беларуси показал толерантность 100 % изолятов к меди в концентрации 0,72 мМ и 21 % из них к 1,08 мМ, что говорит о присутствии в плодовых насаждениях Республики устойчивых к меди популяций возбудителя данного заболевания. Искусственное заражение плодов груши (сортов Велеса и Чижовская) бактериями Pss11.9 показало, что обработка препаратами Дитан Нео Тек 75 и Касумин снижает интенсивность развития заболевания на 33– 45 %.

The analysis of 19 strains of phytopathogenic bacteria Pseudomonas syringae pv.syringae identified in four regions of Belarus showed that 100% of isolates were tolerant to 0.72 mM of copper, and 21 % of them – to 1.08 mM. This indicates the availability of populations of the agent of this disease, which are resistant to copper, in fruit orchards of the republic. Artificial inoculation of pear fruits (Velesa and Chizhovskaya varieties) with Pss11.9 shows that treatment with Ditan Neo Tek 75 and Kasumin reduces the intensity of the development of this disease by 33–45%.
