Starting Your Sustainable Small Farm in Idaho

Take a realistic look at your goals and resources and evaluate what type of small acreage enterprise is right for you.

Students are exposed to various types of farming and ranching systems. Guest farmers speak to the class, and field trips are taken to local farms. Students complete a whole farm plan.

Pesticide Applicator Training

Recertification Credits Available

Valley County's Extension office offers pesticide applicator training each fall. Please contact our office to be added to the distribution list to be notified of these annual trainings.

These classes are open to the public. However, the courses are catered to fill the requirements of recertification credits for private and public pesticide applicators to ensure they maintain levels of competence.

The seminar sponsor issues recertification stickers.

  • Private applicators must obtain stickers totaling 6 credit hours during their licensing period.
  • Professional applicators must obtain stickers totaling 15 credit hours during the licensing period. 

For more information on upcoming workshops, please visit the Idaho State Department of Agriculture Pesticide Recertification Seminars website.
