2. Fields that have been in corn for 2 or more years in an area of severe western 

 corn rootworm infestation (west and north of a line from Dixon to Peoria to 

 Stronghurst) : 



Use Furadan, Buxten, Dasanit, dyfonate, or phorate at 1 pound per acre at 

 planting time, or apply 1 pound of diazinon, disulfoton, parathion, phorate, 

 or carbaryl as a basal application. When using Buxten at planting time or 

 any basal application with no planting-time application, use a diazinon seed- 

 treatment at planting time. 



5. Fields in corn for 5 or more years in the area where western rootworms are 

 not a problem but where northern corn rootworms are a problem: Apply the 

 same controls listed in No. 2. 



SOYBEAN INSECTICIDE SUGGESTIONS 



Green cloverworm : We will tentatively drop toxaphene and add malathion at 1 pound 

 per acre . 



Caution : Carbaryl used at more than 1 pound per acre has injured soybeans. 



SUGGESTED INSECTICIDE CHANGES FOE INSECT CONTROL ON LIVESTOCK 

 AND IN LIVESTOCK BARNS FOR 1969 



Additions to Current Suggestions 



1. Ciodrin (1.0-percent water, 1 pint per animal per week) for face flies on 

 pastured beef and dairy cattle. 



2. Ruelene (crufomate) emulsion, 2 cc. per 10 pounds of body weight, as a 

 drench for sheep -nose bot control. 



5. Toxaphene (0.5-percent water base) for mange control on beef cattle and 

 swine . 



4. Ciodrin for mange control on dairy cattle. 



5. Rabon (SD 8447) as a residual barn spray for house flies. 

 Deletions to Current Suggestions 



1. Rotenone for cattle -lice control on dairy cattle.
