At Krymsk Experiment Breeding Station of VIR, as a result collecting, studying, and selective use myrobalan plum genetic diversity, the intraspecific taxonomy species Prunus cerasifera Ehrh. was clarified. Donors traits significant for breeding were identified and, with their use, adaptable cultivars plum, Russian clonal rootstocks stone fruit plants developed. Intraspecific classification P. i...

Surveys were conducted in 1994 and 1995 to determine the pest status of the American plum borer, Euzophera semifuneralis (Walker), in New York State stone fruit crops. These surveys indicate that American plum borer is the most important of the wood-boring insects infesting tart cherries and also is an important pest in peaches suffering from canker diseases. It is not prevalent in plums or in ...

Plum curculio, Conotrachelus nenuphar Herbst (Coleoptera: Curculionidae), is a key pest of peaches in the southeastern United States. Part of its life cycle, specifically, the pre-pupal, pupal and pre-adult stages are spent in the soil. Experiments were conducted in 2 peach orchards to evaluate the effects of some common orchard weed management practices on the development of the soil dwelling ...

Experiments involving the photosynthetic assimilation of [14C]carbon dioxide by plum leaves (Prunus domestica, var. Victoria) have indicated that D-glucitol (I) (sorbitol), the acylic polyol of these leaves, plays an important role in their metabolism (Anderson, Andrews & Hough, 1961). With leaves previously kept in the dark for 24 hr. a higher proportion of the incorporated 14C was utilized fo...

Thermotherapy and chemotherapy in vitro were applied to eliminate Apple chlorotic leaf spot virus (ACLSV) and Prunus necrotic ring spot virus (PNRSV) from myrobalan (Prunus cerasifera var. divaricata Borgh.), PNRSV from ‘Empress’ plum (Prunus domestica L.) and Prune dwarf virus (PDV) from ‘Early Rivers’ sweet cherry (Cerasus avium (L.) Moench.) plants. ELISA assays conducted one year after ther...

This study was carried out to identify species belonging Thysanoptera in stone and pome fruit orchards the districts (Balya, Bandırma, Bigadiç, Burhaniye, Dursunbey, Erdek, Gönen, Havran, Kepsut Manyas) of Balıkesir Province, Turkey 2018 2019. The survey revealed 32 (thrips) species. Thrips were examined 9900 flowers, leaves, fruits from 198 during research. most widespread (total number sample...

Identifying the key factors underlying the spread of a disease is an essential but challenging prerequisite to design management strategies. To tackle this issue, we propose an approach based on sensitivity analyses of a spatiotemporal stochastic model simulating the spread of a plant epidemic. This work is motivated by the spread of sharka, caused by plum pox virus, in a real landscape. We fir...
