Back Yard Garden Blight that will not go away!
Hennepin County Minnesota
The blight stays in the soil and will affect any vegetable in the same family as the tomatoes. It is important to rotate you vegetables on a 3-4 year basis so you shouldn't plant anything that is related to tomatoes in that spot for 4 years. Beans would be ok. It is important to have good air movement and not overcrowd things as well as watering early in the day and not wetting the foliage.
