POWDERY MILDEW PROBLEMS?
A client of mine is having a heck of a time with plant mildew on her Phlox, which is one of the oldest known plant diseases. A natural fungicide treatment against this mildew is skim milk! 🌱🐄 The first sign of powdery mildew infestation is a white, powdery growth in the branches and leads of the plant. The leaves begin to discolour, before dropping off prematurely. Sometimes, the shoots and leaves may begin to twist. If left untreated, this mildew can severely damage the plant and it is highly contagious, spreading to nearby vegetation.
Organic Treatment: For more than 50 years, researchers in Canada have known that milk sprays can help prevent powdery mildew. But, then the age of fungicides began. Most recently, a spray made of 40% milk and 60% water was as effective as chemical fungicides managing powdery mildew of pumpkins and cucumbers grown in mildew-prone Connecticut. I would suggest using a milder mixture of 30% milk and 70% water. Trial and error always works too. Good luck! Credit: SFGATE, GrowVeg and knickoftime)
