Evaluation of factors affecting avian risk from granular pesticides

Abstract

This manuscript has been reproduced from the microfilm master. UMI films the t»rt directly fi'om the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be fi'om any type of computer printer.The quality of this reprodaction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely a£fect reproduction.In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion.Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand comer and continuing fi'om left to right in equal sections with small overlaps. Each original is also photographed in one exposure and is included in reduced form at the back of the book.
