SLN registrations extended for prairie dog baits
By Randy Buhler CSU Cooperative Extension, Logan County Agent, Agronomy Colorado The Colorado Department of Agriculture has announced the extension of Special Local Need registrations for two new prairie dog baits. We operated on a one-year SLN last year, which terminated March 15. This time we get a two-year SLN for the baits. The two baits are Rozol Burrow-Builder Formula Bait and Kaput-D Prairie Dog Bait. Do not confuse other formulations of Rozol or Kaput with the formulations labeled for prairie dog control. Both baits are anticoagulant products with federal Restricted Use Product labels. A federal restricted use product label requires the purchaser and user of the product to have either a valid EPA Private Pesticide Applicator (blue card) or a Colorado Department of Agriculture Private Pesticide Applicator license. In addition, the 24(c) supplemental label must be in the applicator's possession during application activity. Your pesticide dealer should provide you a copy of the 24(c) label when you purchase the product. Use anticoagulant baits during the fall and winter months to avoid harming burrowing owls and to improve bait acceptance by the prairie dogs. Bait acceptance is a big problem with the old zinc phosphide bait, which requires pre-baiting with plain rolled oats prior to placing the bait around the active burrows. The new baits do not require pre-baiting. Place bait at least 6 inches into only the active burrows. A single baiting is usually effective at 90 percent control or better. A Wildlife reservation official in South Dakota reported better results with one-time per year treatment than when multiple treatments were made. Try to have sufficient help to cover the town in one day. The label requires follow-up to find and bury any prairie dogs found dead on the surface. Tests in Kansas indicated that out of 11,400 treated burrows, only 10 dead prairie dogs were found above ground. Most stay in their holes and die there. With these two new baits, based on chlorophacinone and diphacinone, an antidote is available in case of accidental ingestion. Vitamin K1 is the antidote. The old zinc phosphide bait has no antidote. The baits are effective and much less harmful to non-target species than either zinc phosphide bait or the aluminum phosphide fumigant. Only black-tailed prairie dogs are legal for control with these products. Not all counties in Colorado are included as eligible for use on rangeland and noncrop areas. Logan, Sedgwick, Phillips, Yuma, and Washington counties are listed for control during the period of October 1 through March 15 of the next year. Morgan and Weld are listed for control during the period of November 1 through March 15 of the next year. For Logan County landowners only, the Prairie Dog Rebate program is in place for another year. Contact the Logan County Extension office for information about the program and the rebate form you file to obtain the rebate. The Pest District will rebate product purchases for either Rozol or Kaput products labeled for prairie dog control. Retain your receipts for product purchased. Remember to record your applications to meet the requirement for using a Restricted Use Product. The applicator records must be retained for at least two years. The Colorado Department of Agriculture promises to be diligent in following up on record keeping for applicators using the baits. Date: 12/11/07
