I've been having problems with my tomato plants which seemed to be infected by a virus. The leaves are distorted and fern like. Can someone help me with this.
Much more likely to be herbicide (weed killer damage) -- 2,4-D; or dicamba; or contaminated compost or manures.
For the latter see http://www.puyallup.wsu.edu/soilmgmt/Clopyralid.htm

Jean thanks it seem you are correct since today they look a lot better.
