Do plant diseases die during the winter?

I think I may have some form of wilt in my tomatoes. When I cut them down this fall, will the winter kill off the disease or will it just lay dormant until I plant in the spring? I don't want to use chemicals. Can I burn the affected area?

Ya most can survive winter. Wilt maybe from too much or too little water. In fall remove and burn dead vines, deep till (like plow or double dig) area if possible. Plant very disease resistant varieties next year.

RE: Do plant diseases die during the winter?

If the wilt is caused by a pathogen, then you have a long range pathogen problem. The moist common causes of wilt will persist in the soil and garden waste for up to 7 yrs. You will have to plant affected type plants in a different part of the garden next year. Pathogenic wilts are a progressive disease which will eventually affect the whole plant. Wilting caused by cultural practices will, if corrected, will disappear on new leaves. Your post did not elaborate much so you have to decide the cause. Unfortunately there is no cure for pathogenic caused wilts.
