same tobacco field. It is not pos- 

 sible to control all these insects 

 with any single insecticide, but 

 two or more insecticides may be 

 included in the same dust or spray. 

 TDE, DDT, or endrin will control 

 budworms and climbing cut- 

 worms. TDE or endrin will also 

 control hornworms, and DDT or 

 endrin will control flea beetles. 



SPRAYS 



Combination sprays can be pre- 

 pared by adding to the parathion 

 or malathion sprays described on 

 page 6 a sufficient amount of an 

 emulsifiable concentrate of TDE, 

 DDT, or endrin to make 1 pound 

 of TDE, y 2 pound of DDT, or % 

 pound of endrin per acre. 



DUSTS 



Effective combination dusts 

 should contain — 



1 percent of parathion or 4 per- 

 cent of malathion ; and 



10 percent of TDE or 10 per- 

 cent of DDT. 



If a combination dust is applied 

 to the buds of the plants, it should 

 be used lightly because a heavy 

 dosage is likely to cause plant 

 damage, especially if the plants 

 are wet. 



PRECAUTIONS 



The insecticides mentioned in 

 this leaflet are poisons. Store 

 them where children and animals 

 cannot reach them. Handle them 

 with care. Follow the directions 

 and heed all precautions on the 



container label. Avoid unneces- 

 sary exposure while mixing or 

 applying them. 



Do not apply malathion within 3 

 days before a priming or cutting. 



Parathion is especially danger- 

 ous, and may cause death when 

 inhaled, absorbed through the 

 skin, or swallowed. It should be 

 used only by trained operators 

 who will assume full responsibil- 

 ity for safe use and comply with 

 all the precautions prescribed by 

 the manufacturer. Growers are 

 cautioned not to mix their own 

 parathion dusts. Do not apply 

 parathion within 5 days before 

 handling tobacco or before a 

 priming or 15 days before cutting. 



Avoid getting parathion or en- 

 drin on the skin. Keep them away 

 from the eyes, nose, and mouth. 

 Wear a respirator of a type ap- 

 proved by the U. S. Department 

 of Agriculture. Wear rubber 

 gloves and protective clothing. 

 When using a hand duster, ar- 

 range the discharge tube so that 

 it extends backward behind you. 

 Watch the wind direction and stay 

 out of the dust cloud. If you use a 

 walking traction sprayer, use one 

 that is equipped with a protective 

 shield. Wash your hands and face 

 thoroughly before eating or smok- 

 ing. Bathe after working with 

 these materials and wash your 

 clothing before wearing it again. 



When workers must handle 

 treated tobacco within 5 days 

 after the application of endrin, 

 they should be protected against 

 skin contact. They should wear 

 rubber gloves and tightly woven 

 clothes.
