DIY : Powdery Mildew Spray



Powdery mildew hits pretty hard during the wet months of January and February on the farm. From past experience there are a few little tricks you can try to help minimize the fungal disease. The disease spreads white powdery spots on the leaves and stems of plants, thriving in high humidity and moderate temperatures. Treating powdery mildew is important as it reduces crop yields and can be easily spread.

When you first spot powdery mildew in your garden it is best to remove the affected leaves. I have found that sometimes if caught early enough this can be the best method to remove the disease. Also pruning back extra leaves around the base of the plant allow better air circulation.


  • 1 tsp dish washing liquid
  • 2 tbsp of milk
  • 500ml of water

Mix all the ingredients up in a squirty bottle and then apply to foliage.
