Prof. A. L. Quaintanee." and by Dr. L. O. Howard.' it is the pracl 

 to sift into the leaf bud Pari- green, in corn meal a- a diluent ( 1 table- 

 spoonful of Pari- green to 1 peck of sifted corn meal i. by the use of 

 perforated tomato can- or baking powder boxes, attache*] to handle-. 

 The leaf buds nni-t be kept constantly covered with this mixture, 

 two applications per week ordinarily being sufficient, but three 

 being occasionally necessary. When the mixture is applied at a 

 greater strength the buds are burnt and seriously injured. After the 

 plants reach the height of 2 feet it i- nece->ary to open with one 

 hand and with the other to place a pinch of the mixture in the bud. 

 "While corn meal is largely used a- a diluent it i- al-o a common prac- 

 tice to add lime (air-slaked) and sand. 2 quarts of each to -i of corn 

 meal. The lime, however. >eem- to be objectionable in that it pos- 

 - the propertv of adhering to the tobacco after it is harvested. 

 Again, road dust is occasionally used as a diluent. Corn meal, how- 

 ever, is now used by the majority of the tobacco planters. The worms 

 seem to eat the meal and with it the Pari- green. 



The annual cost in treating the budworm. for labor and supplies, 

 has been estimated by several planters as ranging from $12 to $15 

 per acre. 



When the plants are permitted to bud. for seed, the worms are 

 very destructive, as they bore into the green buds and seed pods and 

 destroy a very large percentage Applications of Paris green assist 

 to some extent in preventing thi> injury. 



Cultural methods in connection with this pest do not seem to have 

 been recommended, nor are they practiced by the tobacco planter-. 

 A- recommended for cotton, corn may be found of sufficient value as 

 a trap crop, when planted around tobacco fields, to warrant it< ttse 

 in this manner. When clean culture between crops is followed, as 

 recommended in connection with the tobacco thrips, the budworm 

 will be in part destroved in the pupa] stage by the plowing of the 

 fields. 



As the pods of the cowpea- are the favorite food of budworm-. 

 when grown in the field between crops (as sometimes practiced) , they 

 should be plowed under or harvested and the held plowed late in the 

 fall. In this way many of the pupa 1 will be destroyed, for it i- in 

 tin- stage that the winter i- passed, from 2 to 7 inches below the sur- 

 face of the ground.
