The root rots of wheat, oats, barley, and rye are among the least conspicuous diseases of cereals, but they are among the most destructive. They are caused by many species of fungi, which are widespread and live on or in seed, soil, and dead plant refuse. They attack a large number of hosts and thrive under a wide range of conditions. To the many types of root rots in cereal crops many names ha...

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 ...

A survey was conducted in 2010-2011 rabi cropping season to obtain information on the distribution and incidence of chickpea diseases in respect to soil type, cultivar used, seed treatment in central and southern parts of India. Local cultivars predominated in most farmers’ fields (25% 48%). 63% of the farmers were practices seed treatment with fungicide. Dry root rot and collar rot diseases we...

Root rot symptoms caused by Leptosphaeria maculans were first reported in Australian canola crops in 2001 but little is known about their importance and prevalence. In a survey of over 100 commercial canola crops in southern NSW, all paddocks had plants with root rot symptoms in 2004, whilst 86% of paddocks did in 2003. Across the two seasons surveyed, there was a strong relationship (r = 0.63)...

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...

Charcoal rot of sorghum causedby the fungus ~acrophorfdna phaseolina is a root andstalk rot disease of great destructive potential in most sorghum-growing regions. Improved, highyielding cultivars under good management tend to be very susceptible to the disease. M. phaseolina is a common soilborne, nonaggressive, and plurivorous pathogen that attacks plants whose vigor has been reduced by unfav...
