INSECTS INJURIOUS TO TOBACCO

Remedies. He recommended " (1) that growers of tobacco 

 avoid planting upon grass or timothy sod; (2) that where grass 

 land is plowed down it would be well to put it in wheat, following 

 with clover, before tobacco. If desirable, corn could follow 

 the grass and the land could be seeded in crimson clover at the 

 last working. This would serve a twofold object by revealing 

 the exact location of larvae in the area under cultivation by their 

 attack upon corn, when they could be destroyed largely by 

 frequent harrowing and rolling, and by affording a most excellent 

 soil crop to turn down the following spring, which would be a 

 decided advantage to the tobacco; that if it is found necessary 

 to have tobacco following grass, it should be broken in the spring 

 as early as possible, and frequently rolled and harrowed, at the 

 same time delaying the setting of the plants as long as possible 

 in order to destroy and starve the larvae within the ground." 



The Spined Tobacco-bug * 



Professor H. Garman has found a small bug, which he has 

 termed the Spined Tobacco-bug, doing more or less injury to plants

in Kentucky, and as this insect is widely distributed throughout the 

 country, it probably does more or less damage elsewhere, though 

 never a serious pest. Concerning its work, he says: " Occa-
