BASF’s Kathie E. Kalmowitz On Downy Mildew

As BASF’s Kathie Kalmowitz made her way across Florida in mid-February, she saw firsthand just how poorly impatiens were faring in landscapes. Every bed Kalmowitz saw was stripped of leaves, the result of a downy mildew pathogen gone wild. Recently, Greenhouse Grower caught up with Kalmowitz, a technical expert who offers guidance to growers in need of getting downy mildew under control on America’s number one bedding plant. GG: Why do you think the impatiens you saw in Florida earlier this year are struggling so mightily with downy mildew? KK: I think the disease has simply been carried over in the soil from the previous year. When plants aren’t cleaned out and the residue is left to rot, the [downy mildew] spores are overwintering. So when the crop is replanted, the crop is coming into contact with those spores. The key is for consumers not to plant impatiens where they […]

BioWorks Introduces RootShield PLUS+

BioWorks announced the arrival of RootShield PLUS+, a new addition to the RootShield Biological Fungicide family, on March 8, 2012. The Environmental Protection Agency granted the product registration in February. RootShield Plus+ has two active ingredients: Trichoderma harzianum strain T-22, and Trichoderma virens strain G-41. It also now provides preventative control of soilborne phytophthora and improved control of hot-season pythium (P. aphanidermatum).

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. […]

Hurricane Fungicide Reformulated

Syngenta’s Hurricane WP fungicide has been reformulated from a wettable powder in a water soluble bag to a new water dispersible granule formulation known as Hurricane WDG fungicide. Hurricane WDG will replace the Hurricane WP currently on the market. “The new Hurricane WDG formulation provides ornamental growers with the same broad-spectrum protection, but now it’s easier to mix and measure,” says Scott Lawson, marketing manager for Syngenta. “The new convenient packaging has been tailored to accommodate growers’ diverse application needs, to ensure they receive the best root and stem protection to deliver the highest-quality plants.”   Now available in 8-ounce containers, Hurricane WDG allows growers to easily measure, mix and apply the fungicide to control major stem and root diseases.

This improved formulation, along with the excellent broad-spectrum disease control, will make Hurricane WDG […]
