Identifying Herbaceous Perennial Diseases

The American Phytopathological Society recently published a book titled “Diseases of Herbaceous Perennials” that lists common diseases of more than 150 popular perennials. Growers may fine the book useful, as it arranges perennials in alphabetical order and includes 700 color images that may help identify diseases. The book is divided into three sections. The first focuses on basic strategies for diagnosing and managing diseases of herbaceous perennials, the second includes short profiles of 12 major types of diseases that attack herbaceous perennials and the third section organizes herbaceous perennials alphabetically by genus and matches common diseases to each perennial. “Diseases of Herbaceous Perennials” can be purchased for $79 plus shipping and handling from the American Phytopatholocial Society.

Pageant Fungicide Now Registered In California

Pageant, a fungicide from BASF Turf & Ornamentals that combines boscalid and pyraclostrobin, recently received state registration for use in California. “Growers everywhere are seeking competitive advantages, including those that help control input costs and boost profit margins,” says Toni Bucci, business manager for BASF. “With Pageant fungicide, growers are able to do more with one disease control application to positively impact their bottom line and produce healthier plants.” Pageant works within minutes of application, inhibiting fungal respiration at two separate sites within the mitochondria of fungal pathogens. In effect, it creates a “double lock-down” on the respiration and energy flow within targeted fungi. For more information on Pageant or other greenhouse products from BASF, click here.

Actinovate Is A Trick Up Your Sleeve

Your plants are potted and the season is going fine. One morning you wake to discover distinctive white or gray spots covering your crop. It’s powdery mildew again, and you need to treat your plants fast. Untreated, powdery mildew can weaken a plant’s structure and impair photosynthesis. Not only does powdery mildew affect the leaf structure of your plants, it also affects the stems, buds, flowers and fruits. An effective tool for treating this disease does not necessarily have to be a standard chemical. Now, you can use an organic alternative that works as good, if not better than, most chemicals. Actinovate SP, a biological fungicide, works to suppress and control powdery mildew quickly and efficiently. Trial photos of plants affected with powdery mildew have shown fungi being suppressed within 24-72 hours after using Actinovate SP. “Of all the diseases Actinovate SP has been trialed against, I think its ability […]

The Broad Approach

Competition challenges growers to stretch their resources effectively, down to every dollar and minute spent producing better plants. Growers depend on new disease management innovations, such as the newly registered Pageant fungicide from BASF Turf & Ornamentals, to grow healthier plants while controlling input costs. With a one-two punch of boscalid, an active ingredient newly registered for use in ornamentals, and pyraclostrobin, the active ingredient in Insignia fungicide, Pageant offers excellent control of a variety of diseases. Among the diseases it controls are downy and powdery mildews, phytophthora fungal leaf spots, anthracnose, rusts and scab, blights like botrytis and monilinia, and crown and basal rots like rhizoctonia, fusarium and cylindrocladium. “Pageant is a broad-spectrum fungicide with activity on all four classes of fungi,” says Todd Burkdoll, technical specialist for BASF. “It gives growers broader fungicidal activity and plant safety than any other product on the market. Growers using Pageant in […]

Detecting Surprise Diseases

Diseases are always on the move, and it’s impossible to predict which diseases will show up in the greenhouse. Growers can, however, learn from the diseases that show up elsewhere. At SAF Pest Management Conference next month, Colleen Warfield of the University of California will share information about unusual disease problems encountered in the last year. And she’ll tell you what to watch for in the year ahead. What is the significance of your topic to growers? “For most growing operations, it is fairly predictable that certain plant diseases will occur every year and on a particular crop. And wouldn’t it be nice if those were the only diseases we had to worry about? “There are two things that the floriculture industry is really good at–introducing new plant materials and sharing plant pathogens. Of course, the sharing of plant pathogens certainly isn’t intended. In fact, an incredible amount of resources […]

Dealing With Viruses

The nature of vegetative propagation and a distribution system that now touches all corners of the world has increased the likelihood of viruses having an impact at your greenhouses. There are, however, ways to detect and emerging methods developing to combat them. Deborah Mathews at the University of California Riverside, will discuss some of those methods at the 25th annual Pest Management Conference next month, and she recently shared a few thoughts on her topic. How concerned should growers be about viruses today? “Viruses and viroids pose an often overlooked threat to the ornamental plant industry. Many times, the infections cause no symptoms in their hosts. But with the transport of tissue culture products, cuttings and whole plants around the world, the introduction of new pathogens, as well as known pathogens to new geographic locations, occurs frequently. “There have been several quarantine events in the United States in the last […]

MIDAS Registration Renewed With No Time Limitation

The Environmental Protection Agency (EPA) recently renewed the registration without time limitations for MIDAS, a broad-spectrum soil fumigant that controls a broad range of soil-borne diseases, nematodes, weed seeds and insects. MIDAS, an Arysta LifeScience product, was developed as a replacement for methyl bromide. It received a time-limited commercial registration from the EPA for one year in October 2007, and it has since been registered for use in 47 states. “The decision by EPA to renew the registration of MIDAS confirms the confidence we already had in this product as the right foundation for success for growers,” says Mike Allan, global product manager for MIDAS. “We have had a year’s time to examine the effectiveness of MIDAS in the fields and have witnessed its successful results first hand throughout the United States. Now growers have the confidence they need to make a seamless transition to MIDAS from methyl bromide.” For […]
