| Donna, Black spot fungus of rose is everywhere. If you have roses, you will have some black spot. There are varieties that are resistant and seldom get black spot. When they do it is usually not a significant problem and seldom if ever requires a spray. Cultural conditions can make black spot a rampant problem or a minor nuisance. Overcrowding, poor air circulation, and frequent wetting of the foliage all predispose plants to black spot infection. Most varieties however, must be sprayed on a regular basis to prevent black spot infections from becoming severe. In severe cases it can even cause defoliation of the plant. There are many fungicide products labeled for black spot on roses. A garden center employee at your local Home Depot store can assist you with selecting a fungicide labeled for controlling black spot fungus on roses. Thanks for the question. Please stop in again soon! |
