PESTICIDE RESTRICTIONS — ILLINOIS 



The chlorinated hydrocarbons- -aldr in, chlordane, dieldrin, endrin, heptachlor, and 

 lindane- -cannot be used on dairy farms except around the farm residence. This ruling 

 was adopted by the Illinois Department of Public Health in 1971. The use of DDT in 

 Illinois is also banned except where special permits are obtained from the Illinois 

 Department of Agriculture or Department of Public Health. 



INSECTICIDE RECOMMENDATIONS, 1974 



FIELD CROPS 



Corn -insect complex in soil . Many farms in Illinois do not have major soil -insect 

 problems in corn. On these farms, and particularly in fields where corn follows 

 soybeans, a diazinon planter-box seed treatment at planting time gives protection 

 against attack by seed-corn beetles and seed-corn maggots during germination. 



Corn-rootworm control . Some major changes in soil -insecticide recommendations for 

 rootworm control have been made for 1974. A new rootworm soil insecticide, Counter, 

 will have a temporary label and sales permit in 1974. Only limited quantities will 

 be available in 1974. Counter, an organic phosphate, has given excellent control of 

 rootworms in research plots and is comparable to carbofuran (Furadan) in effective- 

 ness. Buxten and Mocap are no longer recommended as planting-time treatments for 

 corn rootworm control. These insecticides have given inconsistent control of root- 

 worms in test plots the past two years. 



For a severe corn rootworm infestation, Furadan or Counter applied at 1 pound of 

 active ingredient per acre (a.i.p.a.) will provide the best control. For light to 

 moderate rootworm infestations, planting-time treatments of Counter or Furadan at 

 3/4 pound a.i.p.a., or Dasanit, Dyfonate, Landrin, or phorate (Thimet) at 1 pound 

 a.i.p.a. will give satisfactory control. See table below.

Wireworm, white grub complex . If these insects are expected to be a problem, any of 

 the following insecticides may be relatively effective. If wireworm or white grub 

 infestations are severe, control may not be satisfactory.
