Grape Disease – Powdery Mildew



Seasonal activities: Spring

(mid March through mid June)

  • Pest management. Spray to control brown rot and shot hole fungus as blooms start to open. Sprays may be required at 10–14 day intervals if weather is rainy.
  • Paint trunks with 50/50 mix of white interior latex paint and water to prevent sunburn and borer infestation.
  • Watering. Regular water is important. If available, drip irrigate daily or sprinkler irrigate every 2–3 weeks.
  • Nutrient management. Fertilize before 1st irrigation with 1–2 lb. of urea. Water in.
  • Fruit thinning. Thin fruits to about 4–6" apart when 1/2–5/8" diameter.
