“Home Owner’s Guide to Pesticide Safety”



Intended for persons requiring certification or re-certification in order to apply restricted-use pesticides.  A private applicator is a person applying pesticides to produce an agricultural product (including forestry, nursery or greenhouse) on land owned or rented by the person or the person’s employer. Required for private applicators who apply restricted use pesticides. Examples of private applicators include a farmer applying pesticides to his crops on his owned or rented land or an employee of that farmer doing the same; greenhouse or nursery workers making pesticide applications on the land or in the greenhouses of their employer.

Private and commercial pesticide applicators with certifications that expire January 31, 2020-November 30, 2021, can continue to operate as a certified pesticide applicator until December 31, 2021.  If you are not sure when your certification expires, please call or visit this website.

One of the first steps to having a successful lawn or garden is having your soil tested. A soil test provides more information about the nutrient status of your soil, pH level, organic matter content and texture. The test report also suggests various soil management practices to improve the fertility of the soil for a given crop. 

Follow these steps to properly submit your soil sample:

  • Call the Extension office 920-746-2260 and a “kit” will be mailed to you.
  • Follow the directions to properly sample your soil.  A total of 1-2 cups of soil is required for testing.
  • Cost per sample depends on which test(s) you want the lab to perform, plus $5.00 postage.  LAWN AND GARDEN SOIL SAMPLING INSTRUCTIONS     Lawn-Garden Soil Submission Form
  • Mail your sample to the AgSource/VAS lab.  The lab will send you an invoice for payment, plus $5.00 postage on invoice.
