Epidemics of rust on pear in the Moscow region and ways of its limitations

Abstract

Rust fungi are common parasites, they are also significantly harmful to fruit and small fruits crops. Earlier rust was found on pear mainly in the southern and central areas of horticulture. In recent years it is significantly common and in blackearth zone of Russia, which is apparently associated with climate change, expansion of the area of planting and varietal composition of the culture. The rapid spread of the pathogencould contribute to the active use in ornamental horticulture, gardening and landscape design of juniper, the primary host of the pathogen. But this relationship is not always obvious. To suppress the development of rust on the pear, especially during the years of epiphytotics, along with the organizational and agrotechnical actions using of fungicides is also required. Drugs used against scab are also effective against this disease.
