WINTER BLIGHT. 



181 



cation of the trou- 

 ble is dwarfing and 

 slight fading of the 

 leaves, and the ap- 

 pearance of more 

 or less ill-defined 

 yellowish spots or 

 splashes. These 

 spots soon become 

 dark or almost 

 black, and the leaf 

 curls and becomes 

 s t i ff, the edges 

 drawing downward 

 and giving the 

 plant a wilted ap- 

 pearance. This 

 condition of the 

 leaf is well shown 

 in Fig. 62 (page 

 1 80). The spots 

 grow larger, until 

 they often become 

 an eighth of an 

 inch across, or 

 even more, and 

 they are finally 

 more or less trans- 

 lucent. This in- 

 jury to the foliage 

 causes the plant to 

 dwindle, and the 

 stems become 

 small and hard. 

 Fruit production 

 is lessened, or if 

 the disease appears 



before flowers are 63. A plant attacked by winter blight (at 

 formed, no fruit back), compared with a healthy one.
