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.

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.

Penn State Extension and Pennsylvania growers and packers cooperated with Cornell University in storage trials to assess ways to reduce postharvest disorders in Honeycrisp. Implications from the study are: 1) If risk of bitter pit is high, fruit should be stored without conditioning and marketed earlier than conditioned fruit. 2) Fruit with low bitter pit risk should be conditioned and stored at 38°F if storage periods are uncertain.

Routine assessments of fruit starch levels, ground color and other maturity indices allow growers to make improved decisions about optimum harvest dates for long-term storage. During August through the end of October, 2016, Fruit Times subscribers will receive weekly summaries on changes in fruit maturity and will also be directed to more comprehensive information at the Penn State Fruit Research and Extension Center Seasonal Update site.

Moths of the second generation codling moth, third generation of Oriental fruit moth and the second generations of tufted apple bud moth and obliquebanded leafroller are active and, if present, the injuries caused by juvenile larval stages will be observed at harvest. Woolly apple aphid (WAA) colonies are being observed in many orchards across the region. Control at the correct timing will help manage second summer generation of San Jose scale crawlers. Adult brown marmorated stink bugs will soon move into orchards from surrounding vegetation. Plan ahead with the choice of products utilized against BMSB, and preserve the most effective options for when the pressure from this pest will increase in the later part of the season.

With peach season in full swing, a review of management strategies for controlling brown rot is discussed.

It’s official—we have our first SWD capture at the Horticulture Research Farm at Rock Springs.

Broad mites have potential to be a problem on blackberries once again this year, with damage already being noted in some other states. Generally symptoms show up on just a few plants first, so it is important to recognize them before the problem becomes widespread.

In late 2015 the Environmental Protection Agency issued the long awaited revision to the Worker Protection Standard (WPS). Although it is now technically active it will not be enforced until 2017 but the original WPS will still be enforced until the end of 2016. Please keep in mind that the WPS covers both restricted use AND general use pesticides. This article will deal with the highlights to the revision but also some areas of the current WPS that need emphasized.

To achieve customer satisfaction, growers need to be able to communicate effectively.

A growing percentage of consumers are very interested in understanding how and where food comes from. This trend is a cue to farm and other agricultural producers to prepare to answer questions from customer about production practices.

Material Safety Data Sheets (MSDS) have been renamed and are now referred to as Safety Data Sheets (SDS). According to the Occupational Safety and Health Administration (OSHA), the Hazard Communication Standard requires the new format starting on June 1, 2016. One of the primary reasons for the change is that OSHA requires all SDSs to use a standard format.

According to moth captures in sex pheromone traps located in various orchards in south-central PA, the flight of the third generation Oriental fruit moth (OFM) and the second generation of codling moth (CM) just started this past week. It is probably still too early to initiate control of those pests, however at some locations control may be needed within the next 7-14 days.

Damage from potato leafhoppers is showing up in strawberry and raspberry fields, and by some accounts, seemingly came out of nowhere. This pest moves up from the South in the spring, and by early summer is established in a wide range of crops in the Mid-Atlantic region.
