Tomato Plants

My tomato plants seem to be diseased

Zone Las Cruces, NM. Temperature got up to 106 yesterday but this started during the spring. | Fpavoreal added on June 14, 2015 | Answered

My tomato plants seem to be diseased. What is wrong with my tomato plants? My tomatoes are dying because of some blight which starts with yellowed leaves on the bottom of the plant and proceeds to attack, seemingly from within, up the stalk killing branches one at a time. The leaves die and become dry and brittle and break off. What could this be and how can I treat the tomatoes so as not to lose all of them? This spreads from plant to plant.

I would remove the diseased plants and dispose of properly.
Crop rotation is an important tool for a gardener to lessen diseases in the garden.
