Abstract
Dermal exposure to cypermethrin for applicators was investigated in eggplant fields managed by V and U-shapedtraining. The pesticide was sprayed forward and back on the one side of the furrow, and was sprayed back on the both side.
1) At spraying forward, the exposure in the field by U-shapedtraining was lower on most parts of the body than that by V-shapedtraining. The result came from by less stems and leaves, which caused second contamination during spaying.
2) At spraying back, the exposure indicated the similar tendency. However the exposure at spraying back was clearly lower than that at spraying forward.
3) At spraying back on the both side, the exposure decreased more further than that at spraying back on the one side. This method is very effective to decrease the exposure although the control of a spray pole is a little complex.
