Aerial Swath Widths for ULV Malathion

I.W. Kirk and W.C. Hoffmann


ABSTRACT

An aerial spray deposition study with ULV malathion was conducted to determine if spray swath widths specified in boll weevil eradication program contracts are appropriate for achieving uniform spray deposits across treated fields. The results of the study show that swath widths are too wide for uniform spray deposits using the two aircraft included in the study. Reduction of swath widths would improve uniformity of spray deposition, but this study was not designed to determine whether uniform spray deposits would increase boll weevil mortality in fields sprayed under boll weevil eradication program specifications.
