identification of physiological races of plasmopara halstedii, the causal agent of sunflower downy mildew, in urmia
sunflower downy mildew, caused by plasmopara halstedii, is one of the most important diseases of this crop in west-azarbaijan, urmia. it causes economic yield losses during favorable environmental conditions. the pathogen is a polycyclic one, and it is likely that physiological changes occur in its population and subsequent appearance of new physiological races. hence, identification of the exi...
متن کاملEvaluation of fungicides for the control of downy mildew (Peronospora parasitica) in canola
Downy mildew, caused by Peronospora parasitica Pers. ex Fr., is an important disease of canola that has implications during early seedling establishment. The fungus invades young seedlings and severe infection results in premature defoliation. In worst cases, the systemic infection may even kill the seedlings. Current commercial varieties of canola are very susceptible to downy mildew. Therefor...
متن کاملRapid staining method to detect and identify downy mildew (Peronospora belbahrii) in basil1
UNLABELLED PREMISE OF THE STUDY Demand for fresh-market sweet basil continues to increase, but in 2009 a new pathogen emerged, threatening commercial field/greenhouse production and leading to high crop losses. This study describes a simple and effective staining method for rapid microscopic detection of basil downy mildew (Peronospora belbahrii) from leaves of basil (Ocimum basilicum). • ...
متن کاملDaytime Solar Heating Controls Downy Mildew Peronospora belbahrii in Sweet Basil
The biotrophic oomycete Peronospora belbahrii causes a devastating downy mildew disease in sweet basil. Due to the lack of resistant cultivars current control measures rely heavily on fungicides. However, resistance to fungicides and strict regulation on their deployment greatly restrict their use. Here we report on a 'green' method to control this disease. Growth chamber studies showed that P....
متن کاملMolecular characterization of two types of resistance in sunflower to Plasmopara halstedii, the causal agent of downy mildew.
Depending on host-pathotype combination, two types of sunflower-Plasmopara halstedii incompatibility reactions have previously been identified. Type I resistance can restrict the growth of the pathogen in the basal region of the hypocotyls, whereas type II cannot, thus allowing the pathogen to reach the cotyledons. In type II resistance, a large portion of the hypocotyls is invaded by the patho...
