verticillium wilt verticillium dahliae is now a days commonplace in olive orchards in north of iran. root-knot nematode, meloidogyne javanica, as well is one of the most widely disseminated plant parasitic nematodes in olive orchards of iran. this study was arranged to find the effects of two sets of pot beds on these pathogens' interaction. microsclerotia of verticillium dahliae and j2s o...

B. ANSARI POUR M. NASR ESFAHANI1

The present study is based on the investigation of a soil hyphomyces, Paecilomyces lilacinus, an opportunistic bio-control agent, in controlling root-knot nematode Meloidogyne javanica on tomato in greenhouse conditions. P. lilacinus, effectively promoted the growth of plants inoculated with M. javanica by suppressing its pathogenesis as root galling by the nematode and egg mass production was ...

Polyphenol oxidase (PPO) activities were measured spectrophotometrically in tomato(Roma VF: resistant to Fusarium oxysporum f.sp. lycopersici and susceptible to Meloidogyne javanica) roots inoculated with nematode and fungi in four biological life stages of nematode. PPO specific activity showed a significant decrease in treatments (nematode + fungi) as compared with control plants. Results sho...

one-year-old seedlings of olive cultivars, zard, roghani, koroneiki and manzanilla, were transplanted to different sets of pots each pot containing 2000g of sterilized sandy loam soil. the experiment was conducted in a completely randomized design of 32 treatments, each in five replications. treatments were comprised of: control, mere nematode, mere fungus, and fungus+nematode. pots were inocul...

This research was conducted to study the effect of nematode (Meloidogyne javanica) on severity of tomato Fusarium wilt (Fusarium oxysporum f.sp. lycopersici race 1) and changes in Phenylalanine ammonia lyase (PAL) activity in split-root assays to show the possibility of systemic induced susceptibility caused by nematode to the fungus by local nematode infection. The results showed that the acti...
