Blight ^ Bacillus solanacearum Smith This disease has caused considerable injury South. E. F. Smith has fully de- scribed the disease and recommended as precautions against it an early and com- plete destruction of insect pests, and the removal of any diseased vines. He also advises the use of land on which there have been no diseased plants, together with seed taken from localities where the disease has not existed. J. S. Robinson found that by spraying plants affected with this blight three or four times in the summer with Bordeaux an increased yield of two to two and one- half tons per acre was obtained.

It seldom causes extensive loss, but from the fact that it is more serious on the early crop, the financial loss becomes a factor of importance. This rot may occur at various stages of development of the fruit, generally before it has reached full size, and, as has been stated, early in the season. It makes its appearance at the blossom end in the form of sunken brown spots which gradually enlarge. Such spots are dry and hard. Many times molds or bacteria gain entrance at this point when the fruit is imperfect and cause decay. Such troubles should not be confused with the one under consideration, although they frequently follow Pig. 1. Blossom-End Rot of Tomato.
