A NEW DISEASE OF COTTON IN HAITI 



Figure 14 The name smalling, or stenosis, is proposed on account of the dwarf- 

 ing effect The disease affects the growing tissues of the plants and results in great 

 distortion and reduction of the stalks, branches, leaves and floral organs. It is like the 

 club-leaf disease of cotton in China, but with the distortion and dwarfing symptoms 

 more pronounced, especially in the Upland type of cotton. Since the diseased parts are 

 sterile the production of a crop is restricted to the normal early growth of the plants, 

 which' shows no injury from the disease. This photograph shows the ends of two 

 diseased plants of Meade cotton, the left-hand plant with only slight mjury, the right- 

 hand' plant with the internodes and petioles shortened, the leaves much reduced, and 

 short, abortive, supernumerary branches. (Natural size.)
