Spray drift between trees that were adjacentin the orchard was minimised by shielding trees with a tarpaulin screen during spraying. The first spray was applied on 19 September 2007 when the racemes were at a similar development stage as the racemes in experiment 1. Most racemes were at anthesis by 24 September 2007. The second spray was applied 2 weeks after anthesis on 8 October 2007. Fruit per raceme were counted on 17 October and then weekly until 24 November 2007 and again on 17 December 2007 and 15 February 2008
