With a common ground sprayer of the high- 

 pressure type, use either 4 pounds of 50-percent 

 TDE wettable powder or 2 quarts of 25-percent 

 TDE emulsifiable concentrate (or its equivalent) 

 in 75 to 100 gallons of water per acre. Apply the 

 smaller quantity of spray on small to medium- 

 sized plants and the larger quantity on large 

 plants. If the product you buy is of different 

 strength, use sufficient wettable powder to give 2 

 pounds of TDE per acre, or sufficient emulsifiable 

 concentrate to give 1 pound. 



With a low-pressure ground sprayer use the 

 same quantity of TDE emulsifiable concentrate in 

 about 5 gallons of water per acre. 



For aircraft application use 2 quarts of the 25- 

 percent TDE emulsifiable concentrate in 2 to 5 

 gallons of water per acre, depending upon the 

 capacity of the equipment. 



How To Apply TDE 



In applying either a dust or a spray, cover the 

 plants thoroughly but lightly. The quantity of 

 insecticide needed will depend on the size of the 

 plants. Quantities greater than those recom- 

 mended increase not onh T the cost of treatment but 

 the hazard of harmful or otherwise objectionable 

 residues on the tobacco. 



When To Apply TDE 



Examine each tobacco field for hornworm infes- 

 tation every few days after the plants are about 

 knee high, or when they are smaller in late fields. 

 Apply the insecticide as soon as you find any 

 small hornworms on the tobacco. They can be 

 killed most easily when they are not more than 

 about 1 inch long. Repeat the application when- 

 ever a survey of the field shows the hornworms to 

 be abundant. Hornworms blend so well with the 

 foliage that the plants must be examined closely 

 to determine the extent of the infestation. In 

 most fields one or two applications during the 

 season are sufficient, but as many as four applica- 

 tions may be necessary in some fields when horn- 

 worms are abundant. 



Never apply an insecticide to tobacco as a gen- 

 eral precaution against hornworm attack. To do 

 so may incur unnecessary expense and an exces- 

 sive deposit on the tobacco.
