Late blight is currently a threat to home gardeners as well as commercial farmers. The disease is capable of wiping out entire tomato and potato gardens or commercial fields within a week if the conditions are wet. Farmers who grow tomatoes and potatoes are at serious risk of losing their entire income for the season. Thus it is important for everyone who grows tomatoes and potatoes to be able to identify late blight and know how to control it.
