Chlordane granules : Several have asked if we will recommend chlordane 33.5-percent 

 granules (tradename , Belt). Not for the time being. Belt is a purified form of chlor' 

 dane, one from which practically all of the heptachlor has been removed. We do not knoi 

 how effective this non-heptachlor chlordane will be under corn-growing conditions. We 

 intended to have it in sixteen demonstration plots during 1970, but the truck strike 

 changed our plans. As a result, none was applied. We used 2 to 4 pounds per acre of 

 the old chlordane (with heptachlor) to get the same results as with 1 pound of hepta- 

 chlor or aldrin per acre . Thus , the heptachlor may have been very important . Since 

 we do not know, we will not suggest its use. 



Corn seed beetles" : As a minimum, diazinon seed treater should be used. Farmers who 

 prefer not to do this may apply granules of a phosphate insecticide as a 7 -inch band 

 ahead of the press wheel. Use diazinon at 1.5 pounds per acre, or Dasanit, Dyfonate, 

 or phorate (Thimet) at 1 pound per acre. We do not suggest carbofuran for this pur- 

 pose, because we have not had a chance to see how it does under severe- infestation 

 conditions. Do not use these insecticides on steep slopes, particularly if they drain 

 directly into ponds or streams. Always handle all insecticides with caution and respei,
