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, i/ 2 pound of DDT, or i/ 5 

 pound of endrin per acre. 



DUSTS 



Effective combination dusts 

 should contain — 



1 percent of parathion or 4 per- 

 cent of malathion or thiodan ; 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. Use the recom- 



mended protective equipment to 

 avoid pergonal exposure. 



Do not apply malathion within 3 

 days or thiodan within 5 days be- 

 fore a priming or cutting. 



Parathion and endrin are espe- 

 cially dangerous, and may cause 

 death e „when- inhaled, absorbed 

 through ''the skin, or swallowed. 

 They should be used only by 

 trained operators who will assume 

 full responsibility for safe use and 

 comply with all the precautions 

 prescribed by the manufacturer. 

 Do not apply parathion or endrin 

 within 5 days before 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 that 

 has been tested by the U.S. De- 

 partment of Agriculture and 

 found to be satisfactory for pro- 

 tection against the particular in- 

 secticides you are using. Wear 

 rubber gloves and protective 

 clothing. When using a hand dust- 

 er, arrange 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 smoking. Bathe after 

 working with these materials and 

 wash your clothing before wear- 

 ing it again. 



If you must transplant or other- 

 wise handle plants within 5 days 

 after treatment with endrin or 

 parathion, protect your skin by 

 wearing clean, dry, cotton gloves 

 or a good grade of rubber gloves 

 and tightly woven clothing.
