Dissemination.—Old stalks or stubble in the field may carry the dis- ease over from one season to the next. Wind distributes the spores. The storage rots hold over in dirty bins. Infection.—The Diplodia fungus can enter the roots of the plant, grow upward in the stalk, and invade the ear through the shank. Also spores deposited by the wind can infect the young silk and thus reach the ear. The fungous threads enter the seed, but these seed do not germ- inate, and therefore do not direc

The fungous threads enter the seed, but these seed do not germ- inate, and therefore do not directly transmit the disease. Fields devoted continuously to corn suffer more than others. Wet weather conditions greatly increase the chances of the fungus to affect the Fig. 3. Corn Ear Rot. Note the white growth"of the fungus and the shriveled condition of the grain. Photo, by E. Meade Wilcox. Control.—Destroy trash in the field as much as possible by fall plow- ing. Do not plant corn oftener than once in three years in fields or spots where the disease is bad. Be sure that ears are mature before harvesting and are cured before storing. Storage places must be clean, dry and well ventilated. Disinfect old bins or barrels with formalde- hyde solution, one pint full strength to forty gallons of water. Feed- ing moldy corn to stock may bring on serious disease symptoms, and must be done with the greatest caution. It is best not to feed moldy corn at all. COTTON ANTHRACNOSE. Distribution in North Carolina.—Anthranose has been reported from the majority of cotton growing counties, from Cleveland and Iredell to the coast, and northward to those bordering on the Virginia line. It has been introduced largely in seed from more southern States where the disease is very widespread. Cotton is the only plant affected. Other names for the disease are pink boll and boll rot. Symptoms.—Bolls develop brown sunken spots that enlarge to about half an inch, and develop a pink g
