Most (all?) wine growers today aim for less spraying in the vineyard. Regardless of the products you use when spraying. There are various preventive measures that facilitate this goal. For example, keeping an eye on the weather. To do this, a weather station will help.
The company Cooptain has recently installed eight weather stations in the Crozes Hermitage in the northern Rhône Valley. These weather stations measure temperature, humidity, air pressure, wind speed, wind direction, moisture in the foliage, and more. The wine growers in the region pay a fee, around 500 euros a year, and then they have access to all this information on their computers or phones.
