Prepared by United States department of agriculture. Cranberry plants in Wisconsin and to a lesser extent in Massachusetts, New York. The disease appears to bring about a retrogression of the floral parts of many of the blossoms of the affected plants to foliage leaves, the resulting "false blossoms" failing to produce tendency to develop lateral branches from the usually latent buds below the fruit buds. These lateral branches, fruit. The affected plants have a slender and weak and fail to produce normal flowers or fruit. In other instances, the end of the flowering shoot, instead of forming a fruit bud for the next season, as under normal conditions, continues to grow and produces a long, slender runner. The result of these abnormal developments is that cranberry plants in bogs where tins malformation occurs generally show an excessive growth, usually forming a deep, dense mass of vines. The cause of the false blossom disease is not certain, but specialists of the department who have made studies of the abnormal condition believe it to be due to a disturbance of the nutrition.
