an evaluation on the resistance of the germplasm of cucumber against downy mildew of cucurbitaceae (pseudoperonospora cubensis)
abstract downy mildew of cucurbits is one of the most important diseases of cucumber in humid areas and greenhouses. damage of disease is estimated 50% to 100% in suitable climatic conditions. therefore, achieving resistant or tolerant genotypes can be designed as the most important and safe method to reduce the damage and increase the benefits of cucumber farming. in order to evaluate the resi...
متن کاملControl of Brown Stripe Downy Mildew of Maize by Metalaxyl
LAL, S., S. C. SAXENA, and R. N. UPADHYAY. 1980. Control of brown stripe downy mildew of maize by metalaxyl. Plant Disease 64:874-876. Seed treatment with metalaxyl at 4 g/ kg controlled brown stripe downy mildew (Sclerophthora rayssiae var. zeae) of maize up to 30 days after planting. When combined with seed treatment, one foliar application of metalaxyl (225 ppm) on the 30th day after plantin...
متن کاملResurgence of cucurbit downy mildew in the United States: Insights from comparative genomic analysis of Pseudoperonospora cubensis
Pseudoperonospora cubensis, the causal agent of cucurbit downy mildew (CDM), is known to exhibit host specialization. The virulence of different isolates of the pathogen can be classified into pathotypes based on their compatibility with a differential set composed of specific cucurbit host types. However, the genetic basis of host specialization within P. cubensis is not yet known. Total genom...
متن کاملSeed Transmission of Pseudoperonospora cubensis
Pseudoperonospora cubensis, an obligate biotrophic oomycete causing devastating foliar disease in species of the Cucurbitaceae family, was never reported in seeds or transmitted by seeds. We now show that P. cubensis occurs in fruits and seeds of downy mildew-infected plants but not in fruits or seeds of healthy plants. About 6.7% of the fruits collected during 2012-2014 have developed downy mi...
متن کاملAnalysis of microsatellites from the transcriptome of downy mildew pathogens and their application for characterization of Pseudoperonospora populations
Downy mildew pathogens affect several economically important crops worldwide but, due to their obligate nature, few genetic resources are available for genomic and population analyses. Draft genomes for emergent downy mildew pathogens such as the oomycete Pseudoperonospora cubensis, causal agent of cucurbit downy mildew, have been published and can be used to perform comparative genomic analysi...
