### ⭐⭐⭐⭐ Got rid of white powdery mildew on my plants
*by H***S on 20 August 2022*

White powdery mildew appeared on quite a few of my plants and was killing them off. Purchase this, but the spray end was kinda faulty and took me longer than ever to spray the plants. However, i persevered every 4 days until the plants have no more of that powdery white mildew. I think i will purchase the next bottle from the shop just to make sure it can spray properly
