Soil biofumigation is a widely used farming practice for soil-borne disease management in vegetable crops. the of incorporation fresh plant materials from members Brassicaceae family into soil which release antimicrobial volatile organic compounds (VOCs), namely glucosinolates and their hydrolysis products. However, VOCs may affect non-target beneficial biota including microbial biocontrol agen...

Pathological interrelations of two soil-borne diseases in cucurbits (watermelon, oriental melon, shintosa and cucumber) caused by Fusarium isolates (FI) and the root-knot nematode (RKN), Meloidogyne incognita were characterized by the fusarium disease severity index (DI), RKN gall index (GI) and eggmass index (EI) in inoculation tests using FI and RKN. Virulence of FI as determined by DI at 4 w...

Plant tissue colonization by Trichoderma atroviride plays a critical role in the reduction of diseases caused by phytopathogenic fungi, but this process has not been thoroughly studied in situ. We monitored in situ interactions between gfp-tagged biocontrol strains of T. atroviride and soilborne plant pathogens that were grown in cocultures and on cucumber seeds by confocal scanning laser micro...

Abstract Background Endophytic bacteria have been demonstrated to be one of the most potentially important biocontrol agents for their efficiently improved plant growth and protection host plants from infection by phytopathogens. Results Nine strains endophytic isolated Glycyrrhiza uralensis Fisch. ( G. ) seeds were screened inhibitory effect against 5 fungal phytopathogens using dual culture m...

rhizomania disease is one of the most important threats to worldwide and iran sugar beet cultivation. many studies have been done to understanding the physiological effects of the disease on sugar beet, but in iran conditions has not been done any study for this purpose. this experiment was conducted with four sugar beet cultivars named as brigita, zarghan, jolge and rasoul in 2010 and natural ...
