Knowledge Is Power

Like the swallows to Capistrano, the Crop Protection Handbook has returned for a 93rd edition. For 2007, the all-new Crop Protection Handbook Power Pack includes the print Crop Protection Handbook, the eHandbook CD-ROM and the Global Crop Protection Database and other vital information resources housed at www.meisterpro.com. What’s Inside Here’s what’s in the print edition: Crop Protection Dictionary. The heart of the Handbook is technical, registration and environmental/safety data on every active ingredient and brand name in the global market. New for 2007: Mode of action and action class information for hundreds of active ingredients. Fertilizer Dictionary. Terms and definitions cover agronomics, application, organic materials, manufacturing processes and fertilizer products. A Nutrient Suppliers list provides access to a variety of nitrogen, phosphate, mixed fertilizer and micronutrient suppliers. Sustainable Agriculture. This section focuses on practices such as Integrated Pest Management, genetically enhanced seed, biocontrols, organic production and reduced-risk products. Regulatory Compliance. […]

Essential Oils

Whitmire Micro-Gen has introduced a new line of horticultural oils based on unsurpassed purity. Horticultural oils have been used in the greenhouse and nursery markets for years to effectively control a wide range of insects, mites and diseases on a variety of crops from fruit trees to bedding plants and vegetables. Horticultural oils work by smothering the pest, offering an additional mode of action in rotation programs to prevent resistance buildup. Pests have no resistance to known oils. There are four factors that determine the efficacy and safety of a horticultural oil product. 1) The distillation midpoint  2) The distillation range 3) The purity of the oil 4) Emulsifier selection The distillation midpoint, measured in degrees Fahrenheit, is the point at which 50 percent of the oil has distilled. The higher the distillation midpoint, the longer the oil stays on the plant, allowing it to kill more pests. However, if […]

Partners Against Pests

As researchers and extension specialists work with growers to reach that perfect balance of efficacy and economy in their pest control programs, many find that the pests themselves aren’t the only challenge. Another is the myth that use of conventional chemicals and biopesticides is an either/or proposition. IPM advocates admit it’s easy to see how this myth got started. Organic growers use biopesticides as a stand-alone because most products are registered for use on organic crops. So biopesticides are often linked to organic production. But in reality, only organic growers use biopesticides exclusively. In fact, organic production represents only a small percentage of biopesticide use. All things considered–economics, efficacy, sustainability and crop quality–traditional growers are learning that a program using biopesticides alongside conventionals is often most effective.  Too Much Of A Good Thing Resistance management is one piece of that puzzle. Hired in 1989 as an entomologist at the University of […]

All Predatory Mites Are Not Created Equal

Have you ever considered implementing a biological control program in your greenhouse operation? Well, first of all, what is biological control? Biological control involves the release or application of natural enemies including parasitoids (parasitic wasps), predators and pathogens (in this case entomopathogenic fungi and nematodes) into a greenhouse in order to regulate an existing insect or mite pest population. One of the most widely used groups of natural enemies are predatory mites, which are commercially available from most biological control suppliers. There are a number of predatory mite species commercially available that are in the family Phytoseiidae, including Phytoseiulus persimilis, Neoseiulus fallacis, Neoseiulus californicus, Nesoseiulus longipes and Galendromus occidentalis. It is important to understand the behavioral characteristics of predatory mites before implementing a biological control program since behavioral responses to plant volatiles, feeding preferences and dispersal of predatory mites will influence their ability to provide control or regulate different “levels” […]

EcoSMART Goes Organic With Insecticides

EcoSMART Technologies, a manufacturer of pest management products, has developed an insecticide and fungicide for integrated pest and disease management. Both products are effective against a broad spectrum of pests, and they’re less of a threat to beneficial organisms. Ecotrol EC, the insecticide, has a unique dual mode of action that works by blocking the octopamine receptor in many insects, resulting in paralysis, quick knockdown and kill. Octopamine receptors are unique to insects, and Ecotrol EC has no adverse effects on mammals and birds. Sporan EC, meanwhile, is a fungicide that works as a cell membrane disruptor of fungal hyphae and spores. Sporan EC has both curative and preventative properties, and it is OMRI listed along with Ecotrol EC. “Fortunately for our users, our products are classified as ‘minimum risk,’ have a zero reentry interval and zero pest harvest interval,” says Steve Stringer, vice president of the agriculture division at […]

Zeroing In On Invasives

When American patriot Benjamin Franklin warned, “Never leave that till tomorrow which you can do today,” he was not thinking of fighting such invasive pests as chili thrips or Q-biotype whiteflies. Yet his words ring very true in 2007 as leaders in the greenhouse and ornamental industries are joining together to identify and address tomorrow’s pests today. The topic of “invasive” or “exotic” pests became central to the discussions among researchers at the annual Valent Professional Products Pest Management Conference held in Wyoming. A host of weed scientists, entomologists, pathologists and industry leaders met to discuss trends and issues important to greenhouse and ornamental growers. Topping their concerns was the rapidly expanding list of invasive pests and ways growers, propagators, researchers and industry members can work together to fight them. Though some native populations may explode due to human- or weather-related influences, invasive pests are most often classified as “non-indigenous […]

Grower Tool: Diagnosing Pests In The Northeast

The Interactive Plant Manager, a new online guide from the New York State Integrated Pest Management (IPM) Program, can help growers diagnose and deal with insect pests of ornamental shrubs. Growers can get started from the IPM homepage, found here, by naming the insect involved, the affected plant, the insect category or symptoms of the plant. The Interactive Plant Manager also includes easy-to-read fact sheets, photos of pests and the damage they cause and lifecycle charts to help time the least toxic controls. The focus of the Interactive Plant Manager is common insects of the Northeast. Insects and shrub diseases will be added to the database later this year and into 2009.

Grower Tool: Pest Identification Database

The University of California, Davis has added a pest management database to its agriculture and natural resources Web site that lists hundreds of pests and includes thousands of photos. The Web site can be accessed at http://www.ipm.ucdavis.edu/PMG/menu.homegarden.html. Users will find pest management suggestions specific to many host plants, including more than 30 common garden flowers and 70 ornamental trees and shrubs. Users can select ornamental plants for lists of common pests that affect them, and review pages with identification and management information. For more information on the site, contact Stephanie Klunk at [email protected]

Scotts Pesticide Recall Leads To Firing

Scotts has fired a rogue employee who violated federal requirements for pesticide registration, an action that resulted in a U.S. Environmental Protection Agency order for a nationwide recall. The EPA ordered Scotts, a Marysville, Ohio-based company, to immediately stop selling and distributing products with invalid registration numbers listed on packages. One mislabeled Scotts product is Miracle Gro Shake ‘n Feed All Purpose Plant Food Plus Weed Preventer, and another is marketed under the name “Scotts Lawn Service Fertilizer.” “Over the last several days, we learned that one of our former employees deliberately circumvented company policies, caused invalid product registration forms to be submitted to federal and state regulators and then hid those actions from co-workers and managers,” says Jim Hagedorn, Scotts chairman and CEO. “We sincerely apologize to the EPA, our retail partners, our consumers and our shareholders.” Compliance with government regulation is not optional, Hagedom added, and Scotts has […]
