Abstract
A tunnel sprayer equipped with either two opposing pairs of Curtec ® cross-flow fans, or two sets of three opposing Proptec ® fans, was evaluated for pest and disease control on three dwarf apple cultivars, and compared to a conventional airblast sprayer, in a full-season (12 application) spray programme. Spray systems were evaluated in 20 comparisons of pest and disease control for each of two experiments. Curtec ® and Proptec ® fans provided control that was equal or superior to the airblast sprayer in 85% of insect and disease comparisons. There were no differences in performance between the Curtec ® and Proptec ® fans in 65% of comparisons; the Curtec ® was superior in 15% of comparisons, while the Proptec ®was superior in 20% of comparisons. Curtec ® spray volume (187 or 700 l/ha) did not effect performance in 60% of comparisons; however, the 700 l/ha volume provided superior control in six out of eight comparisons where performance differed. Pest and disease control with the tunnel sprayer (Curtec ® fans) travelling at 8 km/h was equal to or better than that at 4.8 km/h in 80% of comparisons.
