Spray drift continues to be an important issue for commercial pipfruit growers. Off-target agrochemical movement was determined from an apple orchard (Focus Orchard) in Hawke's Bay, New Zealand on 23 September and 17 December 1999, using a Crop liner airblast sprayer fitted with a 920 mm axial fan without straightening vanes. Myclobutinal (Systhane 40 W) at 0.068 kg/ha and diazinon (Basudin 50 WP) at 1 kg/ha were applied for dormant and full foliage treatments, respectively.
