For control, mix a spray containing 1 tablespoon of lead arsenate or 

 2 teaspoons of 50-57$ malathion or 60$ toxaphene emulsion concentrate per gallon 

 of water. A spray containing a mixture of lead arsenate and malathion at the 

 above rates has proved especially effective. 



Caution : Before applying insecticides, read the labels carefully and 

 follow all precautions. This will not only insure personal safety, but will also 

 eliminate insecticide residue hazards. 



For a list of general precautions to use when handling and applying pes- 

 ticides, write to 280 Natural Resources Building, University of Illinois, Urbana, 

 Illinois, for "Safe Use of Pesticides."
