6 • Optimal temperatures for infection are between 21 °C and 32 °C.
• The more hours daily within this temperature range, the higher the risk of infection.
• Days with more than 6 hours in this temperature range: + 20 Points
• Days outside of range (below 21 °C all day or over 32 °C for 6 hours): - 10 points.
• Days with long leaf wetness periods lead to build up of A. Quisqualis. This fungus will break down U. Necator epidemic.
• If leaf wetness lasts longer than 8 hours: -10 points. 
Periods with a risk must be covered by a fungicide applications. In periods with a risk higher than 60 points it is recommended to spray more frequent especially around the time and shortly after bloom.
