Measures for Controlling Powdery Mildew Disease

Cultural Control


Chemical Control

On some plants powdery mildew disease will occur, despite the best attempts at cultural control. Once all cultural control options have been exhausted without satisfactory results, chemical control methods can then be considered.
 
 
  • Foliar applications of fungicides (usually containing sulfur)
  • Systemic fungicides
  • Use a good spreader-sticker with fungicide
  • Begin spray programs as soon as powdery mildew signs/ symptoms are seen (begin disease scouting early)
  • Apply fungicides on a regular schedule, more often during cool, damp weather
  • Always read the fungicide label and follow all precautions and recommendations
  • Be a good steward of the environment. Act responsibly!
