Humidity levels and leaf problems

Another very effective way to prevent mildew is by ensuring that environmental conditions are not conducive to the growth of white powder like mildew .The plants should be grown in areas which are exposed to bright sunlight as the heat in the sunlight will kill the fungi spores causing the mildew to some extent .

The gardener should water the plant early in the morning, so that most of the water will evaporate during the day and humidity levels remain lower, so that fungi cannot flourish .

It is observed that the mildew causing fungi flourish when humidity levels are high, so reducing moisture levels can prevent mildew to some extent.
