Stored grain insect control can start now. With wheat harvest rapidly 

 approaching, take steps to protect the new wheat from attack. Clean out old grain 

 and other debris from in and around the bin. Apply a bin spray of 1.5$ premium 

 grade malathion or 2.5$ methoxychlor to the point of run-off. DDT should not be 

 used for this purpose. 



Treat the wheat with a premium-grade malathion protective dust or spray 

 at the rates recommended on the label. Anyone planning to store oats or shelled 

 corn for longer than six to eight weeks would also profit by using this treatment. 

 Treated grain may be fed to livestock or marketed with complete safety. 



Bagworms are hatching in central and northern Illinois. This is about 

 two weeks later than normal. Apply insecticides in the next week to 10 days in 

 central and northern Illinois. After hatch is complete, apply a spray made with 

 two teaspoons of 57 percent malathion concentrate, 3 teaspoons of 60 percent toxa- 

 phene concentrate or 1 tablespoon of lead arsenate per gallon of water. A second 

 application two weeks later may be needed. Do not apply malathion to Cannart red 

 cedar, as injury may occur. 



Caution : Before applying insecticides, read labels carefully and follow 

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

 nate insecticide residue hazards.
