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 کاملGenetics of growth habit and development of new coleus (Solenostemon scutellarioides (L.) Codd) varieties with trailing habit and bright color.
A high level of genetic variability for growth habit types is observed in tetraploid, cultivated coleus (Solenostemon scutellarioides (L.) Codd). Very few cultivars with trailing habit exist, and those that are available generally have dark green or purple foliage color. Coleus with trailing growth habit is desirable as it increases its utility for use in hanging baskets, mixed containers, and ...
متن کاملNucleotide sequence of the original Brazilian isolate of coleus yellow viroid from Solenostemon scutellarioides and infectivity of its complementary DNA.
The complete nucleotide (nt) sequence of the original coleus yellow viroid (CYVd) from Solenostemon scutellarioides, 'Golden Bedder', has been determined. The covalently closed single-stranded CYVd RNA molecule consists of 248 nt residues which assumes a rod-like secondary structure when folded in the model of lowest free energy. The sequence was determined by direct sequencing of RNA and from ...
