Condensation on Leaf and Flower Surfaces
''Condensation occurs first on the coolest surfaces as air cools and approaches the dew point. Above, dew formed first on the top of rose leaves near the top of the rose plant (which faces the night sky).Moving air within the leaf canopy at night helps move the relatively warmer greenhouse air around the cooler leaf and flower surfaces. Even very small temperature effects matter. The result is that condensation on those important crop surfaces may be prevented or reduced. This has strong implications for disease control.''
Leaf and Flower Wetness Promotes Disease
''Many diseases will get worse with longer leaf wetness periods.''
