The biological efficacy of Prohexadine Calcium a new plant growth regulator, on McIntosh apple was evaluated, comparing two types of pesticide delivery systems. It was found that initial tests in orchard spraying with AI nozzles were promising and that performance between the two nozzle types showed little difference against scab and powdery mildew. Sollanelles et al report reduced spray drift, better deposit uniformity and better spray penetration from spray applications to pear trees with AI nozzles. It was reported that good spray coverage, close to that obtained with conventional hollow cone nozzles, could be achieved on peach trees with anti-drift nozzles and that spray deposits on the sprayer and tractor were reduced.
