If you scroll down the right hand side of this Blog, you'll see that we are constantly adding new blogs that we enjoy or feel would be of interest and value to you. The latest of these comes from our own NCSU Plant Disease and Insect Clinic. This new blog has been created and managed by a Graduate Student in the Plant Pathology Program and offers some insight to both commercial folk and home gardeners. I think you will enjoy it and possibly subscribe to it directly.
