Decay, averaging 13.2 percent per carlot showing decay, was found 

 in 2,860 carlots. or 62 percent of those inspected. Distribution of 

 decay by types was as follows:

All cabbage inspections are summarized in table 20. In many 

 cases the two most important types of decay, alternaria leaf spot 

 and bacterial soft rot, were in early stages or of chief importance on 

 the outer wrapper leaves. Consequently, damage from decay was 

 not so great as might be suggested by the figures. Nevertheless, the 

 summary reveals that 8.2 percent of all heads inspected showed some 

 evidence of decay. Alternaria leaf spot was responsible for nearly 

 two-thirds of the decay and bacterial soft rot for somewhat over 

 one-third. Decay was lowest (2.9 percent) in 1935 and highest 

 (12.6 percent) in 1942. Decay was greatest in cabbage from Florida 

 (11.2 percent) and lowest (1.4 percent) in that from Arizona. The 

 highest incidence of alternaria leaf spot was in Florida cabbage.
