making them more readily accepted than other baits, such as zinc phosphide, which can taste garlicky and induce "bait shyness." It holds up to rainy, wet conditions before and after snowpack—something potato growers need to consider. Under moist conditions, zinc phosphide easily "gasses off"—losing its effectiveness to control voles. Rozol Pellets are labeled for use in border areas and buffer strips adjacent to crops, and is registered for use in all states except Hawaii and Washington, D.C. In all registered states except California, Colorado and New York, it can be broadcast or spotapplied twice per year at a rate of 10 lbs. per acre. Idaho and Washington now have aerial broadcast use 24(c) labels. BioSafe Systems www.biosafesystems.com AzaGuard: BioSafe Systems' AzaGuard is a 3 percent azadirachtion-formulated Insect Growth Regulator (IGR), offering broad-spectrum insecticidal control on more than 300 insect species. AzaGuard works to prevent molting between larval, pupal and nymphal stages while also repelling insects on treated crops, resulting in the reduction of insect damage to plants. AzaGuard is a natural botanical pesticide derived from the extract of Neem seed and meets all of the criteria of the National Organic Program (NOP) for organic crop production. Unlike other azadiractin-based products, AzaGuard extract retains not only azadirachtin but also related liminoids, making it a powerful natural pesticide over a broad range of pests. AzaGuard's natural formula does not induce any mutational resistance and can be safely combined with the BioSafe Systems' activated peroxide line of algaecides, fungicides and bactericides for a systems approach for total Integrated Pest Management (IPM) and disease control around crops and other treated areas. Dow AgroSciences www.blackhawkinsecticide.com Blackhawk: Producers now have another effective weapon to add to their resistance management arsenal. Blackhawk insecticide from Dow AgroSciences provides consistent control of many foliage-feeding insects in a variety of crops, including potatoes and peanuts. Blackhawk features a unique mode of action that provides fast, effective control of many damaging insects. Its broad-spectrum control includes Colorado potato beetle. Blackhawk insecticide is a unique, lignin-based formulation that provides excellent residual control on the foliage for consistent pest control. Spinosad received the 1999 Presidential Green Chemistry Challenge Award and was registered under the Reduced Risk Pesticide Initiative of the U.S. EPA. Blackhawk maintains populations of most beneficial insects while not flaring secondary pests. It boasts a short re-entry and preharvest interval and has shown no phytotoxicity to crops.
