During our August and September sampling we have seen apples mature a little earlier than normal, but then quickly tree-ripen. Between the hot, dry weather and the full sun exposure of trees on size-controlling rootstocks, the harvest window for each of the early varieties has been compressed. Fruits moved quickly from storage-ready to tree-ripe and when left unharvested became destined for cider. This rapid tree ripening can lead to softer apples with poorer quality of late-harvested fruit destined for cold storage.
During the last four weeks we have observed a very sharp increase in the number of brown marmorated stink bug (BMSB) adults collected in various monitoring traps placed around orchards located in southern Pennsylvania. After relatively lower levels of infestation on fruit observed during the last two seasons, this 2016 harvest seems to bring back a serious BMSB challenge.
Fruit have quickly progressed from storage-mature to tree-ripe. In many cases fruits in commercial orchards have softened quickly and wound up being picked for cider. This rapid ripening may also reduce the quality of late-harvested apples, and growers are advised to carefully time harvest based on maturity indices.
This grower-supported apple maturity update focuses on new apple varieties grown at the University of Maryland orchard in Keedysville, to provide pertinent information ahead of the picking dates for growers further north.

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.

Thanks to receiving a multi-state Specialty Crops Research Initiative grant, research and extension activities related to high and low tunnel berry production are taking a significant step forward.
Presumably due to the state receiving some much-needed rain and temperatures cooling off a bit, spotted wing drosophila numbers took a significant jump over the last couple of weeks.
Management strategies are discussed for mitigating the postharvest disease Rhizopus rot on peaches and nectarines.
A review of managing pre- and postharvest apple fruit rots is discussed. Alternative rot management strategies are included.
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.
The spotted lanternfly is an invasive insect that was first found in Pennsylvania in 2014.
For the past few weeks we have been posting information for Brookfield Gala fruit from Keedysville, along with Honeycrisp and Premier Honeycrisp from Mt. Ridge Farms.
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.
The Rural Economic Development Clinic at Penn State Law is now accepting clients for the fall semester. The clinic provides food and agriculture businesses with free legal services on a variety of legal issues.

A three-part video series on best practices for post-harvest washing of fresh produce, including proper use of sanitizers in wash water, is now available on the Penn State Extension site.
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.
