TRIFONOVA, Z. and A. ATANASOV, 2011. Control of potato cyst nematode Globodera rostochiensis with some plant extracts and neem products. Bulg. J. Agric. Sci., 17: 623-627 An experiment was conducted under glass-house conditions to test the effects of five plants products in the form of drenches on the growth of potato and population density of potato cyst nematode Globodera rostochiensis. All t...

Globodera rostochiensis population densities and potato root growth were measured in field plots of one susceptible and two resistant potato cultivars. Root growth and nematode densities were estimated from soil samples taken at three depths between plants within the rows, three depths 22.5 cm from the rows, and at two depths midway between rows (furrows). Four weeks after plant emergence (AE),...

Hatching response of Globodera rostochiensis in potato root diffusate (PRD) collected by soaking individual potato, Solanum tuberosum, root systems in water for 2 hours was used to assess the relationship between root growth and PRD production. Resistant potato cultivars Hudson and Rosa were used as test plants. Maximum hatch occurred in PRD collected 3 weeks after plant emergence (AE) in the g...

Potato cyst nematodes (PCNs), including Globodera rostochiensis (Woll.), are important pests of potato. Plant parasitic nematodes produce multiple effector proteins, secreted from their stylets, to successfully infect their hosts. These include proteins delivered to the apoplast and to the host cytoplasm. A number of effectors from G. rostochiensis predicted to be delivered to the host cytoplas...

Sci., 21: 815–821 Effect of initial population densities (Pi) of Bulgarian population of Globodera rostochiensis on the population dynamics and potato plants growth and yield was investigated in glasshouse and estimated using mathematica...

Transformed roots of the susceptible potato Solanum tuberosum L. cv. Desiree were inoculated with second-stage juveniles (J2) of Globodera rostochiensis pathotype Rol. Adult males emerged after 3-4 weeks and matings with females occurred. After 8 weeks gentle pressure on the eggs of maturing females released the J2 which were viable. Because this technique enables the production of vigorously g...

Overman and Woltz (3) indicated that amino acid antimetabolites applied to tile soil suppressed reproduct ion of Paratrichodorus minor (Trichodorus christiei) and root galling caused by Meloidogyne incognita on tomatoes. Eight DL-amino acid antimetabolites similarly decreased the population of Aphelenchoides ritzemabosi on Lucerne, whereas DL-alanine suppressed the populat ion of Heterodera spp...
