Control of Potato Cyst Nematode Globodera Rostochiensis with Some Plant Extractsand Neem Products
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...
متن کاملProbability of Globodera rostochiensis Spread on Equipment and Potato Tubers.
The probability of spreading cysts of Globodera rostochiensis on farming equipment and potato tubers was investigated in naturally infested field plots. The number of cysts recovered from soil that adhered to equipment differed significantly between different pieces of equipment. These differences were related to initial nematode density and, in most cases, to the volume of soil that adhered to...

متن کاملEarly responses of resistant and susceptible potato roots during invasion by the potato cyst nematode Globodera rostochiensis.
Signals from roots of resistant (cv. Maris Piper) and susceptible (cv. Désirée) potato cultivars during invasion by second stage juveniles (J2s) of the potato cyst nematode, Globodera rostochiensis, were investigated. Novel experimental chambers enabled the recording of electrophysiological responses from roots during nematode invasion. The root cell membrane potentials were maintained througho...
متن کاملRelationship between Root Growth of Potato, Root Diffusate Production, and Hatching of Globodera rostochiensis.
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...
