What is causing this on my tomatos? It has been a cool wet spring. These plants have been in a couple of weeks and look to be dying. Planted where I had zucchini and cucumber last year. The white powder is seven dust.

Yep it is a fungus. I had it bad last year. Sprayed Serenad it is an organic fungicide. Hope it works this year

This stuff overwinters in the soil. Make sure all infected plants and foliage is removed and disposed of in the trash or burned. If not it will keep reinfecting the plants year after year.

Is there anything to do now to save the plants or should I scrap them now?

Copper fungicide can help stop the spread. If a play is pretty far gone it's best to just remove it so it doesn't infect healthy plants. Improving airflow around the plants helps as well. You can cut out infected parts as well but make sure you disinfect the cutting tool with a bleach solution works best. 1 part bleach to 4 parts water.
