Zinc Phosphide: Baiting for Belding’s Ground Squirrels in Oregon

Damage caused by Belding's ground squirrels can be significant. Burrows can undermine building foundations and public infrastructure such as roads and dams. Livestock can be injured from stepping in burrow holes and yield of forage crops can be significantly reduced. All of these potential impacts can carry a huge financial burden to Oregon farmers and ranchers that is not mitigated under the federal EPA label. In this course you will receive training to use Zinc Phosphide to control Belding's ground squirrels in alfalfa, grass hay, pasture and related sites in Oregon under a Special Local Need (SLN) label (EPA SLN No. OR-130002).

The SLN label requires all applicators to complete this training before purchasing, mixing or handling the product. This course, developed through a collaborative agreement between the Oregon Department of Agriculture and Oregon State University, fulfills that training requirement. After your initial training, you are required to retake this course every 60 months. If you have received training on the Zinc Phosphide SLN prior to January of 2020, this course will be particularly useful to you because the SLN has been revised to provide better protection to applicators and handlers, as well as updated considerations required for public safety and wildlife protection.

This course is available to Oregon applicators and those under their direct supervision and will count as two continuing education credits. The Special Need Label is only allowed in Oregon. Applicators cannot use Zinc Phosphide as described in this training in the state of Washington.
