Natural Methods of W**d and Pest Control!!

Almost every gardener faces problems with weeds and pests!! In this fascinating session Dr. Andrew Dolby and REF Board Member Ben Litchfield will discuss evolution theory and why using chemical pesticides and herbicides can lead to more and more pesticide resistant weeds and insects, necessitating more and stronger measures— a sort of “pesticide treadmill.” Fortunately, there are natural alternatives. Each of these will be highlighted and practical examples provided. This session is free and open to all.
