BOZEMAN — The Montana State University Pesticide Education Program, with support from MSU Extension, is offering a pest management tour Oct. 3-6 for pesticide applicators in Private Applicator Training District 5.

The tour will visit seven locations across south central Montana with local support from MSU Extension agents. Private (farm) pesticide applicators may attend a morning or afternoon session for three private applicator credits or both sessions for six credits. Commercial applicator credits are also available and can be viewed on the 2022 pest management tour webpage.

Private applicators in the state’s Private Applicator Training District 5 need to earn six private applicator credits before Dec. 31 to avoid losing their certification, according to Cecil Tharp, MSU Extension pesticide education specialist. District 5 includes Big Horn, Carbon, Fergus, Golden Valley, Judith Basin, Musselshell, Petroleum, Sweet Grass, Stillwater, Wheatland and Yellowstone counties. Applicators can review their credit information at by selecting “pesticide programs” and “pesticide license search” before entering their license number. Applicators can also contact their local MSU Extension office for license information.

Tour presenters include Hayes Goosey, MSU Extension forage specialist, on forage pests; Jane Mangold, MSU Extension rangeland weed specialist, on invasive annual weeds; Tim Seipel, MSU Extension cropland weed specialist, on integrated pest management and herbicide resistance; Uta McKelvy, MSU associate Extension plant pathologist, on crop disease updates; Kevin Wanner, MSU Extension cropland entomologist, on alfalfa and pea leaf weevils; and Stephen Vantassel, Montana Department of Agriculture vertebrate pest specialist, on the management of Richardson’s ground squirrels.
