Rapid 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 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 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 کاملStudy on Effects of Ascorbic Acid and Citric Acid on Vase Life of Cut Lisianthus (Eustoma grandiflorum) ‘Mariachi Blue’
The postharvest life of cut Eustoma grandiflorum flowers is limited in open flowers. Therefore a factorial experiment based on a completely randomized design with ascorbic acid (AsA) at 4 levels (0, 100, 200, 300mg L-1) and citric acid (CA) at 3 levels (0, 100, 200 mg L-1) with 3 replications and 3 samples for each replications, was conducted for this purpose. Results indicated that a significa...
متن کاملTreatment with Essential Oils Extends the Vase Life of Cut Flowers of Lisianthus (Eustoma grandiflorum)
Lisianthus (Eustoma grandiflorum cv. ‘Mriachii Blue’) is one of the most important and marketable cut flowers in the world. However, a relatively limited vase life reduces its marketability. The aim of the present study was to evaluate the effects of essential oils in extending vase life of cut flowers of Lisianthus. For this purpose a factorial experiment based on a completely randomized desig...
