Abstract:
When workers were applying the same volume of a TPN formulation to asparagus fields of the same acreage by a speed sprayer or a conventional power sprayer, their exposure levels to the pesticide were compared. The estimated body exposure level of workers using power sprayer was more than 10 times higher than that of workers using a speed sprayer. The fate of TPN residues in the fields was also assayed. The foliar residues reduced rapidly in one day, but thereafter its reduction rate was very slow, and TPN was expected to remain on the foliage for a long period. However, the airborne TPN concentration was reduced to nil at 1 day after application.
