Anybody know why a plant would turn brown and collapse?

Excessive moisture, planting seeds too deep, and/or planting too early in the spring when soils are too cool can contribute to this problem.

Prevention is possible through soil solarization, plowing the soil prior to planting, planting disease-free seeds and/or transplants, and/or buying seeds treated with a fungicide. Practicing crop rotation and providing good drainage will also help this problem.
