7 Tips For Protecting Impatiens From Downy Mildew

Last year’s outbreak of downy mildew in Europe virtually destroyed the crop and caused garden centers and mail-order catalogs to discontinue stocking it in favor of less problematic crops. A nationwide outbreak here in the United States is probably a stretch because regions experience vastly different environmental conditions. Still, downy mildew was spotted on impatiens on both coasts last year, so growers should be on high alert for the disease. “Impatiens grown in many areas of the United States may never be infected with downy mildew,” says Dr. Colleen Warfield, Plant Pathologist for Ball Horticultural Company. “Other areas may only see this disease sporadically. But if growers and landscapers are not aware of this disease and how to manage it, it certainly has the potential to develop into a far more devastating disease.” Speedling’s Mike Friddle, who was named Greenhouse Grower’s 2011 Head Grower of the Year, says he is […]

Boxwood Blight Spreads To United States

Much like downy mildew and dogwood anthracnose before it, boxwood blight is the latest disease to attack a plant favorite. First spotted in the United Kingdom in the mid-1990s, boxwood blight (Cylindrocladium buxicola or Cylindrocladium pseudonaviculatum) is now thought to be prevalent throughout Europe. In October 2011, this same fungus was confirmed on boxwoods in Connecticut landscapes, garden centers and nurseries. Blight has since been spotted in North Carolina and Virginia, and there’s been one find in the Western United States, as well. Characterized by brown leaf spots with dark edges, blights, black cankers on stems, fruiting structures called sporodochia, defoliation and dieback, the disease attacks all boxwood species. The disease cycle can be completed within a week, and thrives best in warm, humid temperatures around 77 degrees. Although there is no cure to boxwood blight, some best management practices may be employed to keep it from attacking your plants. […]
