Why Milk?
In 1999, a team of Brazilian researchers found that weekly sprays of a milk solution controlled powdery mildew in zucchini squash. In more recent studies, milk or whey-based sprays were as effective as fungicides in controlling powdery mildew in two plantings of wine grapes in Australia. Plant pathologists suspect that as compounds in dairy products interact with sunlight, they cause crippling damage to powdery mildew fungi and spores. If milk works on powdery mildew, I thought it might help with brown rot, which has a similar life cycle.
My subjects were a mature 'Stanley' prune plum and a mature planting of 'Concord' grapes – both easy targets for brown rot and other fungal diseases. In the past, the plum crop was often lost entirely to brown rot, and the grapes typically had half of their fruit ruined by brown or black rot.
Using a hand-held compression spray bottle, I applied a spray using this recipe:
one-half cup organic low-fat milk
1 quart warm water
3 drops dishwashing liquid (to help the mixture stick)
Beginning in early July, I sprayed the plants five times at two-week intervals. I sprayed in the mornings, covering the fruits and foliage until the spray mixture dripped to the ground. I stopped spraying when the fruits began to ripen, because I didn't want milk residue on the fruits.
The results? Less than 10 percent disease incidence on the plum, and less than 30 percent on the grapes – both huge improvements over past seasons.
I'll repeat the method next year, but meanwhile it would be great to hear from other gardeners who have tried milk on other disease problems. Did it work for you as well as it worked for me?
Above: Despite two days of steady rain, ripe 'Stanley' plums did not turn into fuzzy shrunken mummies.
Left: Regular milk sprays suppress powdery mildew on grape foliage, and may help defend fruit from brown rot and black rot, too.






This sounds promising!!

I am using a similar mixture of my own making based on my own research and experience. This year it has given amazing control on powdery mildew on grapes with just two sprays 3 weeks apart with the last spray 2 weeks before harvest. Heavy rains do not seem to nullify the effect. Next year I plan to use it from the start of the season as well for control of black rot on grapes, and brown rot on apricots and cherries. I may even try it for apple scab. A two gallon supply of the mixture is made as follows: 1/4 cup of whole milk powder (must be whole milk powder, not skim milk powder, which I get at a bulk food store) 1/4 cup of sodium bicarbonate (baking soda) 1 tablespoon of horticultural oil (the type sold as part of dormant spray kits but any light oil should do) 1 teaspoon of anti-bacterial soap (the oil and soap act as spreader-stickers so that the mixture adheres to the surface in addition to providing anti-fungal benefits in their own right) Directions: Add 2 gallons of water with a sharp coarse spurt of water from your hose to the whole milk powder and the baking soda so that the contents are very well mixed in solution. When the two gallons are nearly fully added, add the horticultural oil, and just before completion add the anti-bacterial soap (if added earlier you get a lot of suds).
