    Gray mold disease, , is found on greenhouse and field tomato fruit when atmospheric humidity is high. On the fruit, infection usually starts at either the blossom end or the stem end, and when the humidity is high a grayish growth of the fungus develops rapidly and a soft watery rot destroys the fruit. On the stems the fungus usually becomes established on dying tissue at the base of leaf petioles or at the petiole stump left after deleafmg.Once it becomes established on dying tissue, the fungus invades the stem, often completely girdling it and killing the plant. The fungus frequently causes lesions at several nodes on the stem of a plant.
