The essential link between climate and grape quality
When working among the rows, the weather is never just a sideshow: it's a key player, capable of influencing every agronomic decision. Spring can bring abundant rainfall, especially in April, followed by a month of variable temperatures and alternating periods of sun and rain in May.
These conditions require attention and promptness, but they have also allowed the soil's water reserves to be replenished, partially depleted by the lack of winter snow.
As always, the summer's development will determine the rest of the story, but the meticulous work done in spring is an initial investment in the quality of the harvest. Therefore, we observe the start of the season and map out the decisions to be made. Weather conditions, while requiring constant monitoring, are essential for:
Dyellow Blight: Better a Step Ahead Than a Delay
Dyellow blight of grapes, caused by the fungus Plasmopara viticola, is one of the main cryptogamic diseases (which reproduce through spores) that can affect vineyards, especially in conditions of high humidity and mild temperatures.
The first symptoms appear on the leaves with the appearance of translucent spots, known as "oil spots," which later turn yellowish. In high humidity, a whitish mold, formed by the fruiting bodies of the fungus, develops on the undersides of the leaves.
In certain situations, even a single choice can make the difference between a healthy vineyard and a compromised one. Downy mildew does not forgive delays: this requires experience, constant observation, and targeted interventions.
If left unchecked, the infection can spread to the bunches, causing browning and necrosis of the berries, compromising the quality and quantity of the harvest.
