The grape (Vitis vinifera L.) posses several remedy effects. In this study, the anti limnatis nilotica effect of methanolic extract of Vitis vinifera L. plant as well as niclosamide were investigated by anti-leech assay. Distilled water selected as placebo. The mean death time of leeches in groups treated with niclozomide for mature and immature form were 15.4 and 10.1 minutes, respectively. Th...

Grapevine leafroll disease (GLD) is the most important disease of grapevines, occurring in every grape-growing country (Martelli, 1993). GLD affects grapevines adversely, where it delays the maturation of the berries, decreases the accumulation of sugars and affects the overall yield and quality of the fruit (Over de Linden and Chamberlain, 1970). This negatively impacts on the wine industry, w...

What soils are best for grapes? The best grape soils are deep, well-drained loams, free from high concentrations of alkali, boron, or other toxic materials. Deeper soils produce the heaviest crops and are preferred for raisins, common wine grapes, and some varieties of table grapes. However, grapes are adapted to a wide variety of soil types and can be grown successfully on soils not suitable f...

Table grapes (Vitis vinifera cv. Cardinal) are highly perishable and their quality deteriorates during postharvest storage at low temperature mainly because of sensitivity to fungal decay and senescence of rachis. The application of a 3-day CO2 treatment (20 kPa CO2 + 20 kPa O2 + 60 kPa N2) at 0°C reduced total decay and retained fruit quality in early and late-harvested table grapes during pos...
