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 al- 

 drin 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 por- 

 tions 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, and aldrin 

 are poisons; use them according to 

 directions. Avoid inhaling the dusts 

 or sprays. Use a respirator in mix- 

 ing and blending operations. If you 

 spill the concentrated insecticides 

 on your skin, wash immediately with 

 soap and water. Launder clothes 

 that become 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-aii sprayer. Prepare a 2- 

 percent emulsion spray as follows: 



11 tablespoonfuls of 45-percent emul- 

 sifiable concentrate in 1 gallon of water, 

 or 3^/2 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, 

 or 1 pound of dieldrin per acre. Use' 

 the table below in- preparing spray to 

 cover 1,000 square feet of lawn sur- 

 face. Add the insecticide to the 

 amount of water needed (3 to 6 

 gallons) to cover 1,000 square feet.
