Question:
What are the symptoms of downy mildew on impatiens?Answer:
Symptoms of impatiens downy mildew initially appear as yellowing of infected leaves. The yellow-green foliage may initially be confused with a nutritional deficiency. As the infection progresses, leaves may curl downward and a white, fuzzy growth can be seen on the undersides of the leaves. Severe infections lead to early defoliation and blossom drop, leaving bare stems with a few tiny, yellow leaves at the tips of the shoots.
