Use these quantities of insecticide 

 in the amount of water your sprayer 

 will require to cover an acre. 



When applying these insecticides 

 in pastures where dairy animals or 

 animals being finished for slaughter 

 are grazing, avoid area treatment. 

 Treat individual mounds as recom- 

 mended in the preceding section. 



In lawns and park areas where 

 children play, apply half the dosage 

 of these insecticides in the same 

 amount of water. A good watering 

 after each treatment makes it more 

 effective and reduces the toxic hazard. 



If you find it necessary to focus 

 your control efforts on individual 

 plants, use a 5 -percent chlordane 

 dust, a 1 ^-percent dieldrin dust, a 

 2 }£ -percent aldrin dust, a 2 }£ -percent 

 heptachlor dust, or a 0.25 -percent 

 spray. Apply dust or spray around 

 the base of the stem or trunk. Be 

 careful not to get the insecticide on the 

 edible portions of the plant. 



BUILDING AND LAWN TREATMENT 



A 2 -percent chlordane spray ap- 

 plied to foundations and steps and to 

 wires and pipes leading into homes 

 prevents imported fire ants from in- 

 festing homes for at least 60 days. 



An emulsion is very efficient for 

 this type of treatment. Use it with a 



PRECAUTIONS 



Chlordane, dieldrin, heptachlor, 

 and aldrin are poisons; use them 

 according to directions. Avoid in- 

 haling the dusts or sprays. Use a 

 respirator in mixing and blending 

 operations. If you spill the con- 

 centrated insecticides on your skin, 

 wash immediately with soap and 

 water. Launder clothes that be- 

 come contaminated. Do not permit 

 children or pets to go on treated 

 lawns until insecticide has been 

 washed into the soil by rain or by 

 watering. 



compressed-air sprayer. Prepare a 2- 

 percent emulsion spray as follows: 



11 tablespoonfuls of 45-percent emul- 

 sifiable concentrate in 1 gallon of water, 

 or 3V£ pints in 10 gallons of water. 



You can free your lawn of imported 

 fire ants by applying 2 pounds of 

 actual chlordane, 1 pound of aldrin, 

 1 pound of heptachlor, or 1 pound of 

 dieldrin per acre. Use the table 

 below in preparing spray to cover 

 1,000 square feet of lawn surface. 

 Add the insecticide to the amount of 

 water needed (3 to 6 gallons) to cover 

 1,000 square feet. Water lawn after 

 treatment.
