The fungal species Rhizoctonia solani belongs to the Basidiomycota division and is a ubiquitous soil-borne pathogen. It main agent of damping-off disease in seedlings causes root crown rot sugar beets. Plant pathogens deploy small secreted proteins, called effectors, manipulate plant immunity order infect host. Here, gene (RsCRP1) encoded putative effector cysteine-rich protein was cloned, expr...

Rhizoctonia solani is an economically important pathogen of sugar beet (Beta vulgaris L.) causing seedling damping-off, and root crown rot. Cultural practices, partially resistant cultivars, fungicides are among the methods most used to manage R. solani. Penicillium pinophilum, a potential biocontrol agent for was isolated from beet. Our objective evaluate P. pinophilum against AG 2–2 under lab...

American chestnut is one of hundreds of plant species plagued by root rot caused by Phytophthora cinnamomi. Phytophthora root rot is thought to have contributed to chestnut dieback prior to the arrival of chestnut blight, and it may now present a serious limitation to establishment of blight-resistant hybrid chestnut. We manipulated soil compaction and moisture to evaluate the effect of soil ph...

Groundnut root rot is a complex disease affecting the crop production worldwide. The objectives of this study were to: (1) Assess occurrence and distribution groundnut in four main groundnut-growing areas eastern Ethiopia; (2) Identify major pathogens associated with complex; (3) Determine role singly combination on severity under greenhouse conditions. A total 240 fields surveyed over two seas...

A study to determine whether root rot infestations can be detected using high spatial resolution digital multispectral video (DMSV) data was conducted in the Imperial Valley of California. DMSV data were collected on two dates over 25 fields during the summer of 1999 using a light aircraft. The DMSV images included four spectral bands centered on 530 nm, 570 nm, 650 nm and 750 nm, with nominal ...

abstract common root rot induced by bipolaris sorokiniana, is one of the most important diseases of wheat. chemical control of this disease is difficult because of it is a soil-born pathogen, so that, application of other methods is useful to reduce disease level especially resistance cultivars. in this research, were examined reaction of some wheat cultivars and lines against common root rot i...
