 While it's important to scout very often for insects, scouting for disease is no good. This is the most frustrating part with crop diseases, because you have to spray a fungicide well before you see disease symptoms. If you start spraying too late, you may be able to stop the disease from spreading, but much of the yield that you hope to gain has already been lost. With conditions ripe this year for disease, the odds a fungicide will pay in most crops is higher than normal. I'm Darren Hefty.
