Trichoderma species are among important antagonists of plant pathogenic fungi. The main purpose of this study was to evaluate the biocontrol potential of native Trichoderma spp. isolates from sugar beet fields against Phytophthora drechsleri and P. cryptogea, the causal agents of Phytophthora root rot of sugar beet. During 2007–08, 85 isolates of Trichoderma spp. from sugar beet fields in eight...

Rhizoctonia-like fungi were isolated from the infected roots of miniature rose (Rosa hybrida cv. Linda) plant with chlorosis and necrosis symptoms, grown in commercial glasshouse in Rafsanjan, Iran, during the autumn of 2011. All of the isolates were identified as binucleate Rhizoctonia sp. on the basis of hyphal characteristics and nuclei number. They were tested for detection of the anastomos...

In Australia, Fusarium pseudograminearum and F. culmorum are the two main fungi causing crown rot, while Bipolaris sorokiniana is causal agent of common root rot. graminearum typically linked with head blight; however, it has been associated rot in Australia other parts world. This study investigated reactions single cultivars barley, bread wheat, durum oat, triticale to inoculation strains pse...

Objective: The aim of this study was to estimate genetic variability and phonetic relationships of 50 isolates of P. sojae from Iran. Methods: During 2005–2007, 142 isolates of Phytophthora sojae were collected from soil samples and diseased soybean plants from Lorestan, Mazandaran, Golestan and Ardabil provinces. Races of the isolates were determined. DNA of P. sojae...

abstract isolates of rhizoctonia spp., obtained from sugar beet roots and crowns with dry rot symptoms that had been collected from various sugar beet production regions in khorasan razavi province during 2008 and 2009, were investigated in this research. characterization by conventional techniques and molecular methods using species-specific primers was carried out. results showed that from 36...

Cassava root rot disease has been reported to cause huge losses of fresh yield particularly when harvesting is delayed. The improved yellow-fleshed cassava varieties naturally contain antioxidant whereas widely used control plant diseases in the tropics. experiment was carried out at Federal University Agriculture, Abeokuta, Nigeria 2013/2014 and 2014/2015 cropping seasons investigate: 1) possi...

ABSTRACT- The effects of inoculum density and temperature on the disease intensity of Phytophthoraparsiana on almond seedlings were investigated. Almond seeds (Rabie and Kaghazi cultivars) were placed in moist vermiculite at 4°C for 45 days. Germinated seeds were sown in a soil: sand mixture (2:1 v/v) and grown in greenhouse (18°C-25°C). One-month-old seedlings were transferred from the greenho...
