B ► ooks have been written 'on this important subject (such as Lameness in Cattle by Greenough et al) which attests to its importance and widespread occurrence among cattle. As in any other species in which lameness is common, there are numerous causes, but specific problems involving the feet would probably account for about 95 percent of the cases encountered. Foot rot is the term used to den...
Black pepper is the one of most important export products in Vietnam. As the largest exporter, Vietnam’s pepper commodities account for 58% of total worldwide exporters. However, Vietnam’s pepper production is dealing with disease problems, especially foot rot/quick death infected by Phytophthora capsici. The disease results in serious and rapid spread and infection in Vietnam, with yearly redu...
root rot is one of the important diseases of bean in zanjan province and two fungal pathogens, rhizoctonia solani and fusarium solani are the major causal agents of this disease in the region. in this research, the inhibitory effect of n-hexane, di-ethyl-ether, chloroform and ethanol extracts of five plant species, hermel (peganum harmala), thyme (thymus kotschyanus), yarrow (achillea wilhelmsi...
Wood decay mechanisms in Agaricomycotina have been traditionally separated in two categories termed white and brown rot. Recently the accuracy of such a dichotomy has been questioned. Here, we present the genome sequences of the white-rot fungus Cylindrobasidium torrendii and the brown-rot fungus Fistulina hepatica both members of Agaricales, combining comparative genomics and wood decay experi...
A study is described which is unique in that resistance to each of the major diseases which affect production in Merino sheep was measured in the same flock under the same environmental conditions. Results indicated that within the one flock, genetic variation exists for resistance to internal parasites, foot-rot, fleece rot and dermatophilosis. Heritability estimates were similar to those publ...
Although bacteria from the genus Collimonas have demonstrated in vitro antifungal activity against many different fungi, they appeared inactive against the plant-pathogenic fungus Fusarium oxysporum f.sp. radicis-lycopersici (Forl), the causal agent of tomato foot and root rot (TFRR). Visualization studies using fluorescently labelled organisms showed that bacterial cells attached extensively t...
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...
Fusarium semitectum was found to be the major seed colonizing fungus in the commercial acid delinted cotton (Gossypium hirsutum) seed lots. There was no correlation, however, between its incidence and seedling emergence and disease symptoms on the emerged seedlings in autoclaved sand. Inoculation technique simulating internally seedborne nature of the fungus showed that the observed non-correla...
