March 7, lOKi.) Branch-rot of carnations was more serious last season than formerly. This •condition was due, in part, to the pecu- liar weather conditions which were prevalent during the summer. The ex- cessive rains produced plants that were large, bushy and soft. As they made such rapid growth, a large amount of topping was necessary, which increased the number of wounds and so increased branch-rot. Also, the plants being bushy prevented them from drying out completely after the rains, aad this factor also induced this trouble. The fungus causing branch-rot can- not attack a healthy plant below the surface of the soil like stem-rot, but it is more in the nature of a wound para- site, attacking branches where the flower stems and shoots have been broken off and slowly working its way down into the stems and finally killing the entire plant. The fungus also is able to get in at the nodes and kill the young shoots even before they are vis- ible. In bad cases of node infection the nodes become discolored and split and in a short time the whole branch dies. It was observed for the first time this season that the fungus is the principal cause of the dying off of the lower leaves of the plant, especially in cases where the plants have yellows. To Control Branch-Bot. To control this trouble, I would make the following recommendations: It is better, for several reasons, to use a medium-sized sturdy plant than 4 large, bushy one to set in the bench. In planting do not set the plants too close together. Overcrowding will in- crease branch-rot considerably. As in the case of the control of stem- rot, keep the temperature down, espe- cially during the first
