BUD WORMS eat holes through the tips of leaves 

 in the developing bud of the tobacco plant, in 

 both open and covered fields, reduce the yield, and 

 render the product practically worthless except for 

 cigar filler and plug filler. The seed also is injured. 



The " worms," or larvae, hatch from eggs laid on 

 the leaves by a greenish moth, and injury begins as 

 soon as they have migrated from the leaves to the 

 bud — usually in about 24 hours. 



Control measures, described on pages 7-11 of this 

 bulletin, may be summarized as follows: 



Cut and plow under the tobacco stalks as soon as 

 possible after harvesting. 



When fields are shaded with cheesecloth, provide 

 cloth-covered gates and keep them closed, to exclude 

 the budworm moths. Patch promptly all holes in 

 cheesecloth shades. 



Destroy plants in seed beds as soon as possible 

 after a sufficient number have been taken for use in 

 the fields. 



Cover all seed beds with cheesecloth to exclude 

 the moths. 



As soon as plants have become established in the 

 field, apply arsenate of lead and corn meal (1 pound 

 of arsenate of lead to 75 pounds of the meal) to the 

 buds. Continue applications twice a week until the 

 plants are topped.
