When control is absolutely necessary, 1 pound of malathion per acre is 

 recommended. Treatment may be applied to within five days of harvest or use of 

 corn as forage, Malathion can be used on field or sweet corn. Phorate (Thimet) 

 can be used in granular form in field corn but should be applied before tasseling. 

 Parathion can be used to within 12 days of harvesting field corn for grain or cut- 

 ting for forage. However, malathion is the only material recommended for general 

 use. The other materials should be applied only by commercial applicators and 

 should not be applied to seed corn that will be detasseled by hand. 



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.

 pesticides, write to 280 Natural Resources Building, University of Illinois, Ur-

This weekly report was prepared by H. B. Petty, Steve Moore and C. E. 

 White, Illinois Agricultural Extension Service and Illinois Natural History Sur- 

 vey, in cooperation with the USDA Agricultural Research Service, Plant Pest Con- 

 trol Branch, from information gathered by entomologists and cooperators who send 

 in weekly reports from their own localities. 



SPECIAL NOTE TO FARM ADVISERS : 



USDA label approval for use of dieldrin on alfalfa, clover, Irish po- 

 tatoes and sugar beets has been removed . Label approval for use of aldrin on 

 alfalfa, clover and sweet clover in the two-leaf stage have also been removed. 

 If you have followed the recommendations in our Illinois NHE condensed insecti- 

 cide recommendations, you will know that we deleted these recommendations one or 

 more years ago except for dieldrin as a soil treatment for Irish potatoes. Please 

 correct your copies of NHE-94, Insects on Potatoes. Dieldrin can no longer be 

 used as a pre-planting soil treatment in potato fields.
