Sheath blight is considered the most significant disease of rice and causes enormous yield losses over the world. Breeding for resistant varieties is the only viable option to combat the disease efficiently. Seventeen diverged rice genotypes along with 17 QTL-linked SSR markers were evaluated under greenhouse conditions. Pearson's correlation showed only the flag leaf angle had a significant co...

Fusarium head blight is one of the most serious cereal diseases of the world. Epidemics of Fusarium head blight can lead to a decline in grain quality and yield. In addition, grains often become contaminated with mycotoxins, which are harmful to humans and animals. In a field survey of winter wheat in Switzerland, Fusarium graminearum proved to be the most prevalent species responsible for head...

Title of Document: INTEGRATED PEST MANAGEMENT OF FUSARIUM HEAD BLIGHT IN SOFT RED WINTER WHEAT. Elizabeth Reed, M.S., 2011 Directed By: Associate Professor Arvydas Grybauskas, Department of Plant Sciences and Landscape Architecture Fusarium head blight (FHB), caused by Fusarium graminearum, is a destructive disease of the soft red winter wheat grown in the Mid-Atlantic region. Management of FHB...

Taro leaf blight (caused by the Oomycete Phytophthora colocasiae) is a disease of major importance in many regions of the world where taro is grown. Serious outbreaks of taro leaf blight in Samoa in 1993 and in the last few years in Cameroon, Ghana and Nigeria continue to demonstrate the devastating impact of this disease on the livelihoods and food security of small farmers and rural communiti...

Dithiocarbamate fungicides such as maneb and mancozeb are widely used nonsystemic protectant fungicides to control various plant fungal diseases. Dithiocarbamate fungicides should be frequently applied to achieve optimal efficacy of disease control and avoid either decline in effectiveness or wash-off from leaf surface. Dithiocarbamates are of low resistance risk but have the potential to cause...

Late blight, caused by the notorious pathogen Phytophthora infestans, is a devastating disease of potato (Solanum tuberosum) and tomato (Solanum lycopersicum), and during the 1840s caused the Irish potato famine and over one million fatalities. Currently, grown potato cultivars lack adequate blight tolerance. Earlier cultivars bred for resistance used disease resistance genes that confer immuni...

The economic damage accompanying the fire blight is expressed both in loss of crops and costs associated with uprooting infected trees restoration fruit plantations.  Pear characterized highest rates susceptibility to blight. Development genetically resistant cultivars one crucial aspects managing blight, which would allow foregoing current economically or ecologically unsound methods such...

Xanthomonas arboricola pv. fragariae was described in 2001 as the causal agent of strawberry bacterial leaf blight. We report here the first draft whole-genome sequences of five X. arboricola pv. fragariae isolates from Italy and France.

during winter 2004 and 2005, two field and glasshouse experiments were conducted to evaluate the response of 471 chickpea genotypes to ascochyta rabiei, as ascochyta blight (ab) disease in chickpea (cicer aurietimum). frequent rainfall at flowering and pod formation stages made favorite conditions conducive for the infection and symptoms expression. so, the genotypes with high level of toleranc...

A decision support system (DSS) for potato and tom ato late blight m anagem ent has been developed to provide disease m anagem ent recom m endations. The system is com prised of two disease-forecasting tools as well as a simulator. Results from simulation and field experim ents w ith the system have shown that the DSS schedules on moderately susceptible crops did not achieve sufficient disease ...
