Milk has proven effective in treating powdery mildew of summer squash, [15] pumpkins, [14] grapes, [16] and roses. [16] The exact mechanism of action is unknown, but one known effect is that ferroglobulin , a protein in whey , produces oxygen radicals when exposed to sunlight, and contact with these radicals is damaging to the fungus.

That’s powdery mildew, a fungus that affects a wide range of fruits, vegetables and flowers, coating their leaves, stems, blossoms and, in severe cases, entire plants. It isn’t pretty.
Erysiphe cichoracearum is a fungal plant pathogen that causes powdery mildew disease of cucurbits, including melon, cucumber, pumpkin, and squash. [1] The primary symptoms are white, powder-like spots on the leaves and stems. Sphaerotheca fuliginea causes a similar looking powdery mildew of cucurbits.
Ampelomyces quisqualis is a mycoparasite of powdery mildews. It overwinters or survives in the absence of a suitable host as pycnidia. Raindrops cause conidia to be expelled from ripe pycnidia and these may splash onto nearby powdery mildew. Infection is favoured by humid conditions and temperatures in the range 20 to 30 °C (68 to 86 °F) and ...
There are methods to treat powdery mildew using home-made preparations including fresh milk, which contains the active anti-pathogenic compound lecithin. [9] Lecithin is recognized by the European Union as a treatment for powdery mildews diseases and is commonly available in the soy-derived formulation ‘soy lecithin’. [10]
Erysiphe graminis f.sp. tritici is a plant pathogen that causes a fungal infection known as powdery mildew. It is most common in grains, and it can be identified by the characteristic white spots on leaves and stems that appear to be made of powder. Powdery mildew is one of the most widespread and easily recognizable plant diseases.
Erysiphe platani, also known as sycamore powdery mildew, is a fungus native to North America that now infects sycamore tree species worldwide. [2] Infections may spread rapidly in urban settings with large groups of young trees or in plant nurseries. [3] This mildew thrives when there are high humidity conditions during the growing season.
