Industry Company Cracks Unique Forbes List

Which companies will still be around in the year 2109? Forbes magazine put together a list of 100 companies that will still be around, and it included Novozymes A/S, producer of ROOTS products, among companies like BASF, Coca Cola and Toyota among the world’s 100 most sustainable corporations. The list was generated by measuring what companies are doing best in several major sustainability-related areas, including human capital, environmental risks, governance and more. “We are pleased to be included on Forbes’ 100 most sustainable companies list,” says Thomas Nagy, executive vice president of stakeholder relations for Novozymes A/S. “This recognition validates our commitment as a corporation to sustainability and bio-innovation for the future. As the world’s resources become increasingly scarce, we work together with our customers to ‘rethink tomorrow’ and create a more sustainable environment for the world.” Says Novozymes Biologicals President Ted Melnik: “This recognition validates the biological approach offered […]

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 […]

Flagship Granules Approved For California Use

Flagship G can be added directly to plant containers, broadcasted or mixed into growing media. It also features the same spectrum and speed of control as Flagship WG, the existing wettable granule formulation. “Flagship G offers nursery and greenhouse growers tremendous flexibility because it can be applied using a wide range of methods,” says Eduardo Moreira, ornamental market manager for Syngenta. For more information about Flagship G insecticide or other products from Syngenta, click here.

Impact Of Fungicides On Natural Enemies

Previously, I have written articles on the compatibility of alternative pesticides, primarily insecticides and miticides, with biological control agents or natural enemies such as parasitoids and predators. In general, natural enemies tend to be more susceptible to insecticides and miticides than insect and mite pests. However, fungicides are applied routinely in greenhouses to control both aboveground and belowground fungal pathogens. So how compatible are fungicides with natural enemies? Although fungicides may not be directly or immediately harmful to a specific natural enemy, there may be indirect or sublethal effects, such as delayed development of the prey and natural enemy, delayed adult emergence of the natural enemy or decreased natural enemy survival. There is, in general, less information on the direct (immediate) and indirect (sublethal) effects of fungicides on natural enemies. In fact, both the Koppert and BioBest Side Effects Manual/Guide contain minimal information on the effects of fungicides on many […]

Protecting Against Root Rot

Root rot is a continuing problem for today’s ornamental growers. Hurricane fungicide, a new addition to the Syngenta ornamental portfolio, provides effective, easy control of all major root rot diseases, including Pythium, Phytophthora and Rhizoctonia. Hurricane eases the challenges of identifying these various root rot diseases. Hurricane fungicide provides both systemic and contact protection — two different modes of action. This combination of two premiere active ingredients provides optimal, lasting and cost-effective fungi control. Hurricane can be applied to the roots of the plants by drenching using microjet, drip irrigation or with hydraulic systems. It can also be incorporated as a pre-potting media drench. Hurricane can be enhanced to treat stem disease as well, by tank mixing with Medallion to control Thielaviopsis, Cylindrocladium and Sclerotium rolfsi. Syngenta’s Ornamental Market Manager Eduardo Moreira says, “Effective root rot disease control is essential to ensure that growers remain profitable. Hurricane offers growers an easier […]
