%X Application of 0.56 kg benomyl per ha by turbomist sprayer to pruned apricot trees resulted in a slight reduction (P<0.05) in their susceptibility to infection from Eutypa armeniacae ascospores introduced on day 0, but no significant reduction occurred when spores were introduced three or more days later. A majority of the pruned sites yielded less than 3 µg per cm2 of extractable MBC 1 hour after spraying. This finding explains the discrepancy between the high level of protection obtained when the sapwood is saturated by a liberal application of benomyl to each pruned site and the lack of protection in other experiments where the chemical was applied to entire trees by conventional commercial spraying methods.
