Pest and Disease Controls
Effective pest and disease prevention and control are essential for producing high-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 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. Before initiating a control program, we advise consulting with your local cooperative extension service office to ascertain and report pest and disease issues, and, if you are a certified organic grower, with your certifier to confirm the acceptability of specific controls.
