Fiber plants Diseases and pests United States; Sugar crops Diseases and pests United States; Trees Diseases and pests United States; Plants, Ornamental Diseases and pests United States. 276 Wilt and anthracnose protably caused alout the same total losses, tut, due to the fact that wilt is confined to sandy soils and anthracnose generally distri- buted over the entire cotton area, the local v/ilt losses greatly exceeded those from anthracnose. That i s to say, v/ilt in frequent cases causes from 50-90% loss on sandy soils but because it does not occur on clay soils the average state loss is very materially reduced. Anthracnose on the other hand never causes such severe losses as wilt but because of its quite general occurrence the average for the United States is about the same. Root knot and angular leaf spot were also important. Ozonium omnivorum was important locally in Texas, where it undoubtedly produced more damage than all the other diseases combined. Malnutrition, or "rust", continued to bring about its usual amount of loss in situations where an effort is made to raise cotton on depleted soil. Anthracnose caused by Glomerella gossypii (South.) Edg, Anthracnose was reported from Tennessee, North Carolina, South Carolina, Georgia, Alabama, Llississippi, Louisiana, Texas, Oklahoma and Arkansas, It was general throughout all the states reporting its occurrence except in Oklahoma, in which state the infection was local. In South Carolina it was very severe in two of the northern counties. In Alabama it was more severe than in 1917 and 1918, In Arkansas it was slight, and in all the other states it was only moderately severe. The injury in Tennessee was about 25% resulting in an estimated loss of about 8%. In North Carolina the estimated loss was about 5%- In South Carolina the injury ranged between I5 and 20%, the average loss amounting to
