Fig 7. Effect of adaptation treatment on survival of PM411 in blossoms of ‘Comice’ pear and ‘Golden Smoothie’ apple under field conditions.

Environmental conditions during the field experiments are shown in the upper panels. Temperature (dotted line), RH (bold line) and rainfall (vertical bars). Blossoms were treated in the field with either adapted cells (C) (■), or non-adapted cells (N) (○), using a single spray strategy or a repeated spray strategy. Values are the mean of three replicates. Error bars represent the 95% confidence interval of the mean. *, indicates significant differences between treatments according to the Tukey test.
