PEST FOCUS

Highland:

Note on last week's assessment of 'high' Apple Maggot activity: This was based on observations of regional populations, presuming differences in soil moisture and rainfall. The high activity was noted in Hudson, NY, where a resident in-orchard population exists and where there is considerably more rainfall than at the Hudson Valley Lab.
