Notes On Neonicotinoids

Neonicotinoids are highly effective insecticides, but many questions remain about their use. James Bethke at the University of California, Riverside, will discuss neonicotinoids at the 25th annual Pest Management Conference next month. He recently shared a few thoughts on his topic as the conference approaches. What is the significance of neonicotinoids to growers? “Obviously, there is a push to reduce the amount of pesticide use in agriculture and horticulture. There is also a concern about neonicotinoid movement in the environment and its effect on pollinating bees, butterflies, drinking water contamination, etc. In addition, there is a concern about the development of resistance to the neonicotinoids. The results of our research will increase grower knowledge of the neonicotinoids, and how to use them more efficiently.” Are we at a point where much more research needs to be conducted in order to develop best practices for neonicotinoids? “We are finding that there […]

Integrating Biologicals

Over the next 25 years, BioWorks will continue to be an industry leader in developing and commercializing environmentally responsible, safe and cost-effective solutions to the horticulture industry. As the momentum for the sustainability movement continues, growers will demand that the products (e.g., inputs) they use are safe to their crops, their employees and have minimal effect on local and global environments. Consumers are demanding a safe, high-quality food supply. BioWorks’ efforts will help support these demands. Further, integrating biological and biorational pest control products with traditional chemical products provides an ideal tool for the grower to combat the development of chemically-resistant pests and minimize chemical pesticide residue concerns. At BioWorks, we are continually asking the question: “How can we make our products better and more user-friendly?” We are constantly looking for better ways to manufacture our products to achieve the highest quality, efficacy and safety possible. Better formulations, including materials […]

Better Pest Management by Richard Lindquist

It’s hard enough to remember yesterday at my age, let alone to predict the future–especially a future 25 years out. As I thought about things like long-range weather forecasts, preseason sports predictions and pre-primary predictions of who the presidential candidates would be, my confidence returned. These predictions–by experts–are for periods as short as three days and as long as a year or more. And those who predict the weather, sports outcomes and the next president are frequently wrong. I might be just as wrong about an even longer period of time, so here are some fearless predictions of events that probably will not happen and why. Aphids, whiteflies, thrips, botrytis, downy mildews, powdery mildews, root rots and more pests will all disappear. Not gonna happen! The same general group of insects–mite and plant pathogen pests–will continue to entertain the next generation, just as they have for past and present generations. […]

Q-Biotype: What Does It Mean?

A new study shows growers may be keeping a watchful eye on the Q-biotype situation, but many have treatment practices in place that may inadvertently encourage resistance, not fight it. The Q-2006 study was a collaboration of key industry organizations: OFA–an Association of Floriculture Professionals, Society of America Florists (SAF), American Nursery and Landscape Association (ANLA), Florida Nursery Growers and Landscape Association (FNGLA), USDA’s IR-4 and Valent Professional Products. “There’s a lot of talk, and frankly, some fear-driven confusion in the industry about Q-biotype,” says Dr. Joe Chamberlin, field market development specialist with Valent. “Some growers are worrying too much; some may not be taking it seriously enough. The study collaborators saw this survey as a great opportunity to understand what is going on in growers’ minds, and help get the smartest scouting, testing and treatment practices in place to address Q-biotype and overall resistance.” Dr. Lance Osborne, University of Florida […]

Biologicals And Compost Teas Make Media Come Alive

There was a time not long ago when all growers thought that compost or soil in a media mix meant fungal disease problems. A shift is happening in some areas of floriculture to move to media inoculated with compost and living organisms, making a more natural environment for plant growth, with the advantages of increased fertilizer uptake and defenses against pests and diseases. In some instances, biological agents are being added by growers themselves to enrich soils, while some suppliers are offering media premixed with organisms that protect plants. Making Media Alive When growers use a traditional media without live organisms, they don’t enjoy the benefits from nutrient cycling. In a natural environment, microorganisms feed off the plant’s released sugars and the organism provides the plant with nutrients and water, explains Michael Alms, president of Growing Solutions. The company sells the compost tea extractors that provide growers with microorganisms.  “With […]

RootShield WP

Normal 0 false false false MicrosoftInternetExplorer4 RootShield® WP is a new and improved formulation of the highly effective biological fungicide PlantShield® HC–with a water soluble carrier.  RootShield WP protects roots from the most common root diseases affecting greenhouse, nursery and vegetable crops.  The active ingredient, Trichoderma harzianum strain T-22 prevents Pythium, Rhizoctonia, Fusarium, Cylindrocladium and Thielaviopsis by blocking and actively attacking pathogens–”eating” them before they reach the root system. The new RootShield WP makes mixing easier, with its water soluble carrier and virtually clay-free formulation to eliminate clogging.  Additionally, it has a broader label to encompass even more crops, and is labeled for field chemigation. RootShield WP has a 0-hour REI and can lower growers’ costs by eliminating or reducing the need for chemical root fungicides, and saving material and labor costs of repetitive drenching.  One application provides up to 12 weeks of protection and costs less than 1 to […]

Insecticide For Thrips Control

“There is scientifically documented resistance by western flower thrips to several leading thrips products, and many growers are in need of products with new modes of action,” says Joe Chamberlin, field market development specialist for Valent. “The chemical industry has introduced very few effective thrips materials in the last 10 years, and in many cases growers are down to one effective product. Overture is a valuable tool for growers seeking effective control, Chamberlin says, because it acts through both contact and ingestion activity. It controls immature and adult thrips. “Overture has a unique mode of action and can therefore be rotated with all other thrips chemistries,” Chamberlin says. “By introducing Overture into a pest management program, growers can alleviate current problems with resistant thrips, and also slow development of resistance to currently effective products.” For more information about Overture or other products from Valent, click here.

Identifying Natural Enemies

A new pocket guide developed by the Michigan State University (MSU) Integrated Pest Management (IPM) program can make the identification of insects and spiders easier. “Identifying Natural Enemies in Field Crops” (MSU Extension Bulletin E2949) is geared for field crops, but the guide is appropriate for use with other crops. It provides information about a variety of common beneficial insects, both predators and parasitoids. The 46-page field guide features color pictures of common beneficial insects and spiders, in addition to information on identifiable traits and details about their lifecycles and diets. Contents are divided according to the major category of natural enemy: beetles, true bugs, lacewings, predatory flies, parasitoids and ants. Another section is dedicated to spiders. “Identifying Natural Enemies in Field Crops” is available for $10 ($7 per copy for orders of 10 or more) and can be purchased online at www.emdc.msue.msu.edu/ or by calling 517-353-6740. Sample pages can […]

New Whitefly Biotype Has Growers Concerned

Two of the more devastating silverleaf whitefly biotypes are the B and Q biotypes. The B type has been in the United States since its discovery in 1985, and the Q type is still a grower concern in 25 states. Both types of whiteflies can reduce the yield of a broad range of agricultural, fiber, vegetable and ornamental crops. The aggressive B biotype arrived in the U.S. from its native Middle East and Asia Minor range, and it threatened agricultural production throughout the southern United States until new integrated pest management strategies brought it into check. The Q type brings new challenges. The biotype was first detected in the U.S. in December 2004 on poinsettias from an Arizona retail outlet. Compared to the B biotype, Q is less susceptible to many pesticide types, which means there are fewer chemical options for its control. There is also concern that resistance to […]
