Impatiens Downy Mildew: 2013 And Beyond

Between warnings from garden writers and the national media and extensive signage at garden centers and retail outlets, the public was well aware of a problem with Impatiens walleriana this year. “Some people reported they couldn’t sell the Impatiens walleriana they grew because the press had been so alarming to gardeners that they weren’t purchasing them,” says Cornell’s Margery Daughtrey. Growers were also aware of possible problems with impatiens downy mildew and made adjustments to their production. From what Daughtrey observed in the market, the amount growers cut back on producing Impatiens walleriana varied quite a bit in 2013. Some box stores asked growers to produce them, and that was probably the main channel for their distribution this year, she says. Other growers cut back by 40 to 100 percent. “If they did not cut back extensively, some of them were left with plants that just didn’t sell,” she says. […]

The New Generation Of Verbenas

Verbenas have come a long way since their early days of seed propagation and bedding plant packs. The introduction of Verbena ‘Homestead Purple,’ developed by Allan Armitage in the 1980s, ushered in a new era of vegetatively propagated verbenas. Suntory soon followed suit with their Tapien and Temari series, and breeders haven’t looked back since. Ranging from trailing basket dwellers to sprawling landscape plants, verbenas are a well-known staple in the garden. Their vivid colors and robust blooms draw customers’ attention in the garden center and spice up the blandest garden corner. Thanks to breeders’ efforts, verbenas are easier to grow than ever.

Impatiens Downy Mildew Found In Ohio

The devastating impatiens downy mildew disease has been found in Ohio for the 2013 growing season, according to a report from The Ohio State University Extension.  “In the last seven to ten days there have been several reports of impatiens downy mildew’s appearance in the Midwest; as of this time we have two reports from Ohio,” according to an article on the Ohio State University Extension website written by Francesca Peduto Hand and Nancy Taylor. “The pathogen that causes the disease, Plasmopara obducens, is extremely aggressive on bedding plant impatiens and Ohio’s impatiens producers should be aware of and scouting for this disease.” The article cites the early symptoms of impatiens downy mildew as a slight curling or mottling of the foliage, which may be subtle. High humidity, however, can result in a heavy coating of white sporulation on the underside of the leaves. “One grower described white dust floating above the […]
