Sugar-cane, Cotton, and Tobacco 233 



successful in combating the disease. Planting a grain crop 

 x>n the ground in the fall and following the next year with a 

 crop of cowpeas of the iron variety is a method used by some 

 farmers to prevent the disease. 



Root-rot. The plants affected with rot wilt suddenly and 

 later die. Deep fall plowing and the growing of some other crop 

 on the land for a few years are of use in fighting the disease. 

 In choosing a crop in place of the cotton, the planters must 

 avoid sweet potatoes and alfalfa, which are also attacked by 

 root-rot. 



TOBACCO 



137. Tobacco-growing districts. The tobacco plant may 

 be grown successfully in all latitudes of the United States and 

 on a great variety of soils. But the value of the crop is influ- 

 enced so much by the climatic and soil conditions under which 

 it is grown that the industry has become specialized in certain 

 districts and it is there that the trade seeks the product. Each 

 special district produces a certain type of tobacco and the 

 methods of growing and handling the crop vary according to 

 the type of leaf that it is desired to produce. General cultural 

 methods are, however, somewhat similar. 



138. Classes of tobacco. Three general classes of tobacco 

 are grown, (1) cigar tobaccos, (2) export tobaccos, and (3) 

 manufacturing tobaccos. Cigar tobaccos are those to be 

 made into cigars, export tobaccos are those to be sent abroad, 

 and manufacturing tobaccos are those to be used in the making 

 of products other than cigars. Each of the general classes may 

 be subdivided into types. For example, cigar tobaccos may 

 be wrapper leaf, binder leaf, or filler leaf. In export and manu- 

 facturing tobaccos are such types as flue-cured, Virginias un- 

 cured, and white burley. Each of the different types is pro- 

 duced on a special kind of soil and according to different methods 

 of curing and handling. Cigar tobaccos are grown chiefly 

 in certain sections in Connecticut, Massachusetts, New York, 

 Pennsylvania, Ohio, Wisconsin, Florida, Georgia, and Texas.
