Fungicide Efficacy Against Calonectria pseudonaviculata, Causal Agent of Boxwood Blight

Mechanisms of antagonism of Pseudomonas fluorescens EPS62e against Erwinia amylovora, the causal agent of fire blight.

Pseudomonas fluorescens EPS62e was selected during a screening procedure for its high efficacy in controlling infections by Erwinia amylovora, the causal agent of fire blight disease, on different plant materials. In field trials carried out in pear trees during bloom, EPS62e colonized flowers until the carrying capacity, providing a moderate efficacy of fire-blight control. The putative mechan...

The Efficacy of Fungicide Application to Control Fusarium Head Blight Infection in Spring Wheat

Genetic Diversity and Phylogenetic Study of Xanthomonas arboricola pv. juglandis the Causal Agent of Walnut Bacterial Blight Disease

Bacterial blight (Xanthomonas arboricola pv.juglandis) is one of the main diseases of walnut that reduce the yield in the central, western and northern regions of Iran. This disease was first reported form, Qazvin and Mazandaran, then widely reported from northern, central and western provinces. To identify the cause of the disease in different provinces, infected leaves collected from Alborze,...

pathogenicity variation of didymella rabiei causal agent of chickpea blight from ilam and kermanshah provinces

abstract ascochyta blight caused by didymella rabiei is one of the most important diseases of chickpea in ilam and kermanshah provinces, iran. in order to determine the pathogenicity variation of didymella rabiei populations, infected plants in field crops of different regions of both provinces were sampled. one hundred isolates were isolated by chickpea seed meal dextrose agar media. these iso...
