The Tobacco Biidworm. n

Planters should keep these points clearly in mind, because the 

 difference between a valuable tobacco crop and one of less than 

 ordinary quality is often dependent upon the care with which bud- 

 worm control is practiced. 



Direct control in Florida and Georgia should begin as soon as 

 possible after the plants have become established in the field. Ajjpli- 

 cations of the poison mixture should be made in the buds from then 

 until the plants have been topped. It is of special importance to 

 emphasize the necessity of beginning the applications of the poison 

 mixture as soon as the plants are set in the field. A delay in starting 

 this work may give time for the eggs that are introduced from the 

 seed beds to hatch, and for the young larvae (young budworms) to 

 reach the bud and do considerable damage. For the best results the 

 buds must be treated twice a week until topping has been completed. 



The best mixture which has been employed in experiments under 

 actual field conditions is 1 pound of arsenate of lead and 75 pounds 

 of corn meal (approximately 6 heaping teaspoonfuls to 1 peck of 

 corn meal). Bolted or sifted meal is preferable to the unsifted prod- 

 uct. In the preparation of this mixture care should be taken to 

 obtain an even distribution of the poison throughout the corn meal. 

 For this purpose mechanical mixers have been employed where large 

 quantities are necessary. These, however, are not essential, for with 

 a little care the mixture can be prepared quite as well by hand. 



Caution. — Calcium arsenate should 7wf be used as a substitute for 

 arsenate of lead in the budworm poison mixture.
