THE LOQUAT AND ITS RELATIVES 263 



trees during the spring months. Infected twigs should be cut 

 off well back of the diseased area and burned, care being taken 

 to sterilize the pruning shears in alcohol or formalin after each 

 cut so as to reduce the danger of further infection. Occasionally 

 entire trees are killed by the blight, which gradually extends 

 downward from the branches into the trunk, although in most 

 cases the disease does not seem to progress much beyond the 

 branches. Some varieties are more susceptible than others. 

 For example, the Advance is quite resistant and the trees of the 

 Victor, which were very susceptible when young, have in later 

 years become more or less immune; the Champagne showed 

 considerable blossom blight in the spring of 1914, but to no 

 greater extent than young trees of other varieties. The trees 

 seem to gain resistance as they grow older." 



In regard to the scab he says : " This is reported to be 

 a serious disease of the loquat in Australia. The fruit is 

 attacked when half grown by brownish black spots, which soon 

 extend, stop its further development, and disfigure its appear- 

 ance. The fleshy part of the fruit becomes desiccated and the 

 skin seems to cling to the stones. A large proportion of the 

 crop may in a short space of time be rendered absolutely un- 

 salable. It is also well known in Italy upon the leaves. In 

 California the scab is quite common both on nursery and 

 bearing trees, attacking both leaves and fruit. . . . Spraying 

 with Bordeaux mixture after the blossoms have fallen and the 

 fruit is setting should prove an effective remedy." 



In Florida the flowers are sometimes blighted by the an- 

 thracnose fungus (Colletotrichum glceosporiaides Penz.). Bor- 

 deaux mixture, prepared according to a 3-3-50 formula, should 

 be used to combat this disease. 



E. O. Essig * mentions four insects which occasionally attack 

 the loquat in California. One of these is the well-known 

 codlin-moth (Cydia pomonella L.). Another is the green apple
