The mighty annual hero has fallen and the villain has a name: downy mildew. Shade-tolerant impatiens were one of the most popular landscape annuals for years. However, due to the spread of downy mildew, gardening has changed.  Continuing the push to vanquish downy mildew, English Gardens will not be selling impatiens this year. 

The Avenger Alternatives to Downy Mildew

Downy mildew affects all types of standard impatiens (Impatiens walleriana), including doubles, minis and interspecific hybrids such as Fusion. Even if you were to purchase impatiens that are disease free, it is just a matter of time.

Downy Mildew is to Impatiens as Kryptonite is to Superman

Downy Mildew is fungal blight very similar in appearance to Powdery Mildew. However, unlike Powdery Mildew, Downy Mildew has no cure and the plant will eventually weaken and die.

Symptoms of impatiens with downy mildew vary depending on how advanced the disease is.  Light-green yellowing of the leaves and leaves curling downward with gray markings or white fungal growth are sure signs of the disease. Some advanced symptoms include stunted plant and leaf growth, bare plants as the result of leaf and flower drop and softened, weak stems.

Downy Mildew spreads faster than a speeding bullet

Well, maybe not faster than a speeding bullet, but it spreads fast. The disease began in Europe, spread to Florida and eventually made its way to Michigan. The disease spreads through spores that grow on the undersides of infected leaves. The spores easily detach from the plant and spread by wind or water splash. Spores can travel hundreds of miles via wind currents, and plants not yet showing symptoms may unintentionally infect those around them.

It spreads most easily in moist conditions. Regardless of this past winter, downy mildew survives in the soil and on plant debris. Today, there is no product on the market that will cure this disease. There are however preventive fungicides that will help control Downy Mildew but only when used on an aggressive schedule.  Environmentally and monetarily, this is not a realistic approach since most chemicals need to be applied every 7 days by a certified applicator. Experts are working to develop a cure and advance ways to eliminate downy mildew.
