I need help! I am a school teacher, new at organic vegetable gardening and have started a school garden this year. Our potatoes seem to have blight. Small brown spots on the yellowing leaves. Should I spray with some type of organic fungicide? Is it too late? and if it is too late, if I dig them up can I replant something else that might grow this summer in that same raised bed?
Thanks for any help you can give this newcomer!

This type of problem may occur for many reasons, attack of aphid,drought (less watering), Capsid bug and blight. For blight it should be brown patch, not a tiny spot. Find out which one of above is the reason, then we have to select a way to put a stop.
