The numbers of brown marmorated stink bug adults are increasing in many orchards. Codling moth adults will be active for at least another 2 to 3 weeks. The fourth generation Oriental fruit moth adults are likely to be present in orchards during all of September and into October.

Employers must often keep up with a variety of required government posters at their orchards, farms, or other places of business which can be daunting at times. Earlier this month, the U.S. Department of Labor changed two posters that employers are required to post in the workplace.

It is August already, which, for many grape growers in Pennsylvania, means veraison and the beginning of fruit ripening. It seems a good time to comment on the seasonal weather and how it can affect the vines.

While the harvest of peaches and nectarines is in a full swing and it is only a matter of a couple of weeks when we will start the fully fledged harvest of apples, it is still important to remember that some important fruit pests are still active and can cause damage of fruit.

Codling moth (CM) second generation adults are very active in most Pennsylvania pome fruit orchards. All stages of brown marmorated stink bug (BMSB) including young summer adult bugs are being observed in and outside of orchards. The third and probably fourth generation Oriental fruit moth (OFM) adults are also active in both, pome and stone fruit orchards.

With an early bloom, many people have been expecting an earlier harvest this year. This initial week’s sampling of Premier Honeycrisp and Honeycrisp indicates that Premier may be ready to be spot-picked as early as next week.
