Prevent and Control Powdery Mildew with Milk Spray
Select the Right Milk Type for Effective Powdery Mildew Control
Selecting the proper type of milk is crucial for managing powdery mildew treatment with milk spray. It is sometimes advised to consume whole milk rather than skimmed or reduced-fat types because the fat and protein in whole milk, particularly lactoferrin, boost the antifungal effect of sunlight.
Since skim or non-dairy milks (such as almond or soy) don’t have enough protein, full-cream dairy milk is the best option for making powdery mildew spray. For organic powdery mildew, pasteurized milk works just as well as raw or unpasteurized milk, but raw milk’s inherent bacteria make it even more effective.
To avoid any residual sour smells from fungal diseases, make sure the milk is fresh before applying it to plants. For milk spray formulations that seek to enhance plant health, 2% or whole milk is a common option due to its accessibility and effectiveness.

When using milk to prepare a powdery mildew treatment, refrigerate it properly before using it for optimal results. It is crucial to adhere to this selection process to produce a potent spray that will shield your plants against fungal growth and keep your garden free of dangerous fungi.
Milk Type | Effectiveness | Protein Content | Notes |
---|---|---|---|
Whole Milk | High | High | Best due to fat and lactoferrin |
2% Milk | High | Moderate | Good alternative, widely available |
Skim Milk | Low | Low | Lacks sufficient protein |
Raw Milk | Very High | High | Bacteria enhance antifungal effect |
Non-Dairy (Soy) | None | None | Ineffective for mildew control |
Non-Dairy (Almond) | None | None | Ineffective for mildew control |
Prepare a Precise Milk-to-Water Ratio for Optimal Spray
