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 […]

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.

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 […]

Whitefly Watch

Whitefly control has been a challenge this year, the Society of American Florists (SAF) reports. In order to avoid serious problems later in the season, scientists in the field and on the Ad Hoc Whitefly Task Force advise growers to watch their spray programs carefully to be sure they are working. Resistant whiteflies, and/or increased numbers of whiteflies, have been reported by growers in several parts of the United States. It is extremely important that growers who notice apparent resistance in whitefly populations send whitefly samples for biotype identification. The Q-biotype, first discovered in the United States in 2004, is resistant to many, but not all, of commonly used chemicals. Is the B-biotype developing stronger resistance as well? Only grower-scientist cooperation can provide that answer. Samples can be sent to any of several labs with guarantees of anonymity, and no regulatory action will follow. But knowing which biotype a grower […]
