Seeing is Believing with Pesticide Applicator Training Abstract One of the most difficult audiences to teach and reach through the creation of a meaningful interactive learning environment is the audience which is "required to attend." This is the typical audience of any recertification training for private or commercial pesticide applicators. Our training consortium took an entirely different teaching approach by utilizing small group, interactive breakout sessions. Training began with participants quickly writing down the steps to prepare a boom sprayer for the upcoming season. A visual demonstration, using a Spray Chek sprayer simulation table, graphically corroborated the effect of common errors on spray patterns; namely, boom nozzle spacing, excessive or insufficient nozzle height to target, plugged nozzles and nozzles with different spray angles. Alternatives to typical flat fan nozzles, like the Turbo TeeJet or XR (extended range) nozzles were shown. The group was divided into equal groups for three-30 minute interactive exercises. Stations consisted of: sprayer pressure gauge testing and how water-sensitive paper can be used to determine efficacy of a spray application; the inaccuracy of using common items, like a quart jar or coffee cup, to guesstimate or measure pesticides; and how to detect cracks and avoid rupturing older, sun-exposed polymer bulk tank for pesticide storage. Each attendee received an accurate 2-quart measuring cup with their certification experience. Of the 151 respondents in this year's training, only one person stated that they didn't like the teaching methods used. This unsolicited comment says it all, " Used to be as dry as high school English–now enjoyable "!
