PEST FOCUS

Geneva:

1st catch of Green Fruitworm 4/9. Degree day accumulation is well below "Normal". At this point it's probably not all that meaningful and can "catch up" with just a few relatively warm days, but it certainly looks to be a more "Normal" season than last year.

Highland:

Pear Psylla laying eggs. First Green Fruitworm trap catch 4/9. McIntosh at Green Tip.
