SPECIAL ISSUE 



m 



. q '&68 November 29, 1967 



We receive many inquiries about changes in recommendations in the fall of each year 

 but prior to the publication of printed circulars. We are sending you these Spe - 

 cial Suggestions and Major Changes for 1968 to help answer your "early" questions. 

 No caution statements , time limitations between application and harvest, or rates 

 per acre are included. This information should be on the label. These special 

 suggestions will appear in printed form in University of Illinois College of Agri- 

 culture Circular 899 and in the Illinois Custom Spray Operators' Training School 

 Abstracts of Presentations. 



These statements have been reviewed by entomologists of the Illinois Natural His- 

 tory Survey and University of Illinois College of Agriculture and were prepared by 

 H.B. Petty, Steve Moore, Roscoe Randell, and Don Kuhlman from information gathered 

 by entomologists in Illinois and the USDA Agricultural Research Service. 



SPECIAL SUGGESTIONS AND MAJOR CHANGES FOR 1968 



CHANGES IN SUGGESTIONS DURING 1968 



As of January 1, 1968, use of a pesticide on food or feed will not be approved un- 

 less definite tolerances, no matter hoiv minute, have been established for each crop 

 and each chemical. Under certain conditions, there may be a date extension of this 

 regulation. Although it is hoped that all manufacturers of pesticides used on Il- 

 linois crops will have complied and no labels will have been rescinded, the user 

 should be alert for legal changes during 1968. If some changes become necessary 

 during 1968, they will be announced publicly; it will, however, be impossible to 

 revise this circular until November, 1968. 



DAIRY FARMS 



Dairy farmers are cautioned against the use of the chlorinated hydrocarbons, aldrin, 

 chlordane, dieldrin, DDT, endvin, heptaohlov, or lindane — either as foliar treat- 

 ments or soil treatments, even though they have been used for many years. The tol- 

 erance in milk, for most of these insecticides, is still zero. Even slight drift 

 onto dairy pastures, hay crops, or other dairy forage crops will result in minute 

 but traceable amounts in milk and body fat, which will then be excreted in the 

 milk- -presenting a legal problem, not a public health problem. 



Because of possible drift, do not apply sprays or dusts of aldvin, DDT, chlordane, 

 dieldrin, heiptaohlov, or lindane to fields adjacent to dairy hay, pasture, or en- 

 silage crops.
