Yep, try it. I've found a 1 part milk to 2 parts water to even deter 'rust' on my roses. found this at the Nichols site
Milk may have potential as a fungicide.
A report in the October 16 1999 edition of New Scientist suggests that spraying diluted milk on cucumbers and courgettes (zucchini) may be effective in killing powdery mildew, caused by the mold Sphaerotheca fulinginea. This could be a significant benefit for organic farmers trying to meet the growing demand for chemical free vegetables.
According to the report, milk's fungicidal powers were discovered by Wagner Bettiol of the environmental laboratory of Embrapa, the Brazilian Agricultural Research Corporation, in Jaguariuna, north of Sao Paulo.
Bettiol, who was looking for cheap ways to control plant pests, observed that by-products from milk-processing factories killed powdery mildew on squash. So he decided to simply spray fresh milk on the plants to see if it had the same effect.
To his surprise, he found that it did. In fact, spraying heavily infected plants twice a week with a mixture of one part cow's milk to nine parts water was at least as good at stopping mildew as the chemical fungicides fenarimol and benomyl, Bettiol discovered.
Bettiol added that several organic growers in his region were able to control less severe outbreaks by spraying once a week with a 5% milk solution. In many cases, milk was both faster and more effective. After two to three weeks of spraying with milk, the area of leaves infected was in some cases only a sixth or less of the area affected on plants treated with chemical fungicide.
Bettiol is not yet sure why milk works so well, but he speculates that it helps the plants in two ways. Milk is known to kill some microorganisms. It also contains potassium phosphate, which boosts the plant's immune system and so may help it inhibit the mildew's growth.
