THE TOBACCO BUDWORM AND ITS CONTROL. 11 



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 emploj^ed in experiments under 

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

 of corn meal. 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 

 Avhere great quantities are necessary. These, however, are not essen- 

 tial, for with a little extra care the mixtures can be prepared quite 

 as well by hand.
