Pest and Disease Controls

Effective pest and disease control is essential for producing premium-quality crops. Johnny's offers information, tools and supplies to help you prevent, identify, and control many pest and disease issues. The majority of our line of repellents, fungicides, herbicides and insecticides are approved for use in organic production and listed by the Organic Materials Review Institute (OMRI), and some by the Washington State Department of Agriculture (WSDA). See our Pest & Disease Control Comparison Chart for options and recommendations. We advise consulting with your local cooperative extension service office to ascertain and report pest and disease issues, before initiating a control program, and if you are a certified organic grower, always consult with your certifier to confirm whether or not a specific control is allowed.



Johnnys is committed to your success and is with you every step of the way.
