Select resistant varieties
Choose plant types which are immune or less prone to powdery mildew.
Right spacing

Watering techniques
Water the plants at the bottom without sprinkling on their leaves; this reduces moisture content around foliage.
Pruning
Carry out regular pruning of plants for better circulation of air and cut off any infected parts instantly.
Healthy soil
Boost soil fertility by incorporating compost manure and organic materials that will enhance plant resistance against diseases.
