In the last few years, southwest tomato crops have been cut to maybe 20% of what we used to harvest by a virus spread by the beet leaf hopper, which overwinters on wild mustard (among other things). The Beet Leaf Hopper is new to New Mexico. The virus kills tomato plants sometimes almost overnight. If the plants survive, the fruits have hard white patches and rot quickly. So far, I've found nobody with any suggestions on how to combat this problem. ???
