Bagworms should already have hatched in southern Illinois. As soon as 

 you notice the small hags, apply control measures. For small amounts of spray, 

 use 1 tablespoon of lead arsenate, malathion wettable powder. Sevin wettable powder 

 or 60$ toxaphene emulsifiable concentrate, or 2 teaspoons of malathion emulsifiable 

 concentrate per gallon of water. Do not use malathion on Cannert red juniper. 



Elm leaf beetles have been feeding on Chinese elms in some areas. Sevin 

 or lead arsenate sprays will control these pests. 



Horn fly and stable fly numbers vary from herd to herd, but they are be- 

 ginning to build up. Beef cattle can be sprayed with 0.5$ toxaphene sprays; dairy 

 cattle, with sprays containing 1.0$ DDVP or 0.1$ pyre thr ins and synergists. 



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.
