Powdery Mildew Got Ya Down?

One of the gardeners expressed concern about a powdery substance on her brussles sprouts. It is likely to be powdery mildew, a disease that cabbage & squash get sometimes, especially in our cool, fall weather.

An excerpt from the linked article:

Powdery mildew thrives in temperatures between 60 and 80 degrees. Dry, shady conditions are ideal, as are areas with poor air circulation. Planting disease resistant cultivars and making sure you allow for good air flow are two ways to guard against powdery mildew. Inspect plants regularly during warm, dry conditions, and remove any leaves that show signs of infection. Destroy (do not compost!) infected plant parts. A spray made with baking soda, if applied weekly at the first signs of infection, can protect plants against further damage. Plants that are badly infected should be ripped out and destroyed to prevent the disease from spreading further.

Baking Soda spray:

  • 1 gallon of water
  • 1 tablespoon of baking soda
  • 1 tablespoon of vegetable oil
  • 1 tablespoon of dishwashing liquid
