The Grape Vine Downy Mildew Infection models are pointing out date and time of infection. Wine Growers have the informaiton about their last spray against this disease. The models grouped under this topic provide helpful information to assess if a new spray is needed or not.
For this two basic information are assessed. First we show the rain from events giving more than 2 mm accumulated for 3, 5, and 7 and 14 days. With this informaiton you can assess how many rain has been diluting the protectant spray on the leaf and if it might be still present or not. The second informaiton we like to provide is an assesment of the number of leaves formed on every shoot within the last 7 days.
