In this study, the biological control activities of bacteria strains, which have been isolated from volcanic, sandy, salty soils and Ebu Cehil plant Calligonum polygonoides L. subsp. comosum (L’Hér.) were investigated against isolates Rhizoctonia solani causing root rot in beans. As result isolation, 83 strains obtained identified by biochemical tests fatty acid methyl esterase analyses. vitro ...

This study was carried out to determine the anastomosis groups and disease severity of Rhizoctonia solani, which causes root collar rot in chickpea production areas Konya. A total eleven isolates spp. were obtained isolations made from plants surveys. examined microscopically grouped as multinucleate, binucleate according number nuclei. Ten multinucleate identified R. while one isolate sp. In p...

To study the mechanisms of inducible disease resistance in conifers, changes in transcript accumulation in roots of Norway spruce (Picea abies (L.) Karst.) seedlings exposed to the root rot pathogen Ceratobasidium bicorne Erikss. and Ryv. (anamorph: Rhizoctonia sp.) were monitored by differential display (DD). Because C. bicorne attacks root tips, a desiccation treatment was added to exclude ge...

Cylindrocarpon destructans/Ilyonectria radicicola is thought to cause both rusty symptom and root-rot disease of American and Korean ginseng. Root-rot disease poses a more serious threat to ginseng roots than rusty symptoms, which we argue result from the plant defense response to pathogen attack. Therefore, strains causing rotten root are characterized as more aggressive than strains causing r...

Microplot and small field-plot experiments were conducted to determine the effects of Pratylenchus penetrans on strawberry yield over several seasons and to evaluate the effects of nematode control on strawberry vigor and yield. Pratylenchus penetrans alone or in combination with the black root rot pathogen, Rhizoctonia fragariae, reduced strawberry yield in microplots over time. There were no ...
