GrapeMilDeWS is an expert-based approach for the integrated pest management (IPM) of two of the major pathogens of grapevine (Vitis vinifera): Erysiphe necator which causes powdery mildew and Plasmopara viticola which causes downy mildew. GrapeMilDeWS has been designed and tested by a team of phytopathologists. It is presented here as a formal model in Statechart. We argue that formal modelling...

Methanolic extracts of eight medicinal plants were screened for their anti-mildew activity against Plasmopara halstedii, incitant of downy mildew of sunflower. Extracts of Morinda citrifolia, Zingiber officinale, and Tinospora cordifollia were found to be best in reducing the sporulation of P. halstedii in both the whole leaf and leaf disc method. Further; the phytochemical analysis of these ex...

Wine grape cultivar selection was examined as a use of biotechnology and a part of integrated plant disease management in grape and wine production. The efficacy of 18 wine grape cultivars against various wine grape diseases was examined using a relatively low-input fungicide regimen to determine whether these diseases can be managed under hot and humid southeastern Virginia conditions over 5 y...

There are two mildew diseases affecting cucurbit crops: powdery mildew and downy mildew. Both fungal pathogens produce wind-dispersed spores that can be moved long distances, thus they cannot be avoided. Fungicides and resistant varieties have been important for managing these diseases. Unfortunately, both pathogens have demonstrated ability to evolve new strains that are not controlled as effe...

Downy mildew is a destructive disease of spinach worldwide. There have been 10 races described since 1824, six of which have been identified in the past 10 years. Race identification is based on qualitative disease reactions on a set of diverse host differentials which include open-pollinated cultivars, contemporary hybrid cultivars, and older hybrid cultivars that are no longer produced. The d...

Industrial revolution no doubt is adding a lot to the human life but at the same time it is polluting the atmosphere as well. Agricultural industries are no exception. In order to crack the demand and supply gap, it became essential to minimize the losses on the farm and increase the yield; various control strategies, which include chemical applications, have been developed and are in practice....

Fruit firmness and crispness are important traits of cucumber because they directly affect its commercial value. We performed quantitative trait locus (QTL) analysis these fruit texture with the double-digest restriction-site-associated DNA sequencing (ddRAD-Seq) technique detected 31 QTLs for firmness: 11 placenta firmness, 12 skin 8 flesh firmness; 25 crispness-related scores: 10 index, appar...

Camelina [Camelina sativa (L.) Crantz] is an emerging oilseed crop combining both industrial and agronomic advantages. seed yield, oil protein contents, fatty-acid composition, vary across genotypes, environments, agricultural practices. However, no studies have been conducted to identify rank major limiting factors explaining yield quality variations under on-farm conditions. performance was m...
