The first part of my research involved verifying the theory that vineyard blocks where the intensity and frequency of downy mildew symptoms are low are home to a greater abundance of microorganisms ...

Studies have shown that this material can significantly reduce the growth of Plasmopara viticola, a pathogen that causes grapevine downy mildew, by 80-90%.

A research team identified a P. viticola-resistant locus, Rpv34, in table grapes through analysis of a high-density genetic map with 826 SNPs derived from F 1 progenies of 'Moldova' (resistant ...

Plasmopara viticola’s growth depends on meteorological variables, like temperature and rain, plant’s genotype, the degree of exposition to oospores and soil conditions. Field measurements are ...

Grapes Grapes are particularly vulnerable to downy mildew caused by Plasmopara viticola. Symptoms include pale yellow spots on leaves, leading to rotting and premature dropping of berries. Cultural ...

But, last year, southern Italy was hit by incessant rain in May and June, leading to a proliferation of the fungus Plasmopara viticola, which thrives in warm, humid conditions.

The early recognition of a specific disease on a plant permits of intervening quickly and efficiently, avoiding the spreading of the infection on all the plants, reducing the use of substances, and ...

As Italy's autumn grape harvest begins, winemakers are braced for a sharp drop in output after a rampant fungus ruined vines, thriving on drought followed by torrential spring rain.

The slump is due to the combined effect of poor weather and damage from a fungus called plasmopara viticola. The fungus causes one of the most devastating diseases of grapevines and is also known ...

However, production was expected to slump around 20% in central regions and about 30% in the south, hit by a combination of bad weather and the impact of a fungus called plasmopara viticola ...
