Apple scab lesions appeared April 17 on trees that were not adequately protected March 20-25. This could have led to severe secondary infection April 18-23. Proper and thorough coverage at this time of the year is critical for preventing infection of young fruits. This article contains updates on pome and stone fruit diseases and new fungicide properties.
Earlier this year, a podcast series “Social Media and Food Retailers: Consumer Perspectives” was released on YouTube to describe the results of a consumer study designed to better understand how consumers use social media to engage with food retailers. Social media tools (Facebook, Twitter, blogs, etc.) allow for two-way communication between the consumer and the food retailer, and these research results provide important insights for food retailers interested in enhancing their marketing efforts.
The growing season began early this year in Pennsylvania, so that means that many of us have already been hard at work preparing yards and gardens for the impending warmer weather.

Looking at the comparisons of accumulated degree-days (base 43) for the last 6 years, as of April 20 we are still about 100-150 DD ahead from any other year or about 200-300 DD ahead of the average DD accumulation for this time of the year. And while this difference is becoming smaller as the spring progresses (especially when compared to the weather pattern during the spring of 2010 season), this unusual weather seems to have caused a lot of confusion in the insect world that surrounds our fruit trees.
With the warm weather insects are early this spring. Growers have seen damage from onion, seed corn and possibly cabbage maggot. Onion maggot damage of 10-20% has been confirmed in two fields in the Shippensburg area. Bean seed maggot was confirmed in Northampton County yesterday.
Given the growth stage of berry crops and the current weather, frost protection is on everyone’s mind. In this update, you will find a re-run of a portion of a frost-related article, and some frost-related “Berry Good Questions” from past years paraphrased and condensed, plus a couple of new ones thrown in. Most of this information is also contained in Appendix A in the Mid-Atlantic Berry Guide, along with a lot of other frost-protection information.
The warm spring weather has sped up the arrival of some common turf insect pests.
With the extremely wet soils all last season, we’ve seen many samples with Phytophthora.
We have known for more than 80 years that post-bloom temperatures can influence harvest date, but not until recently have we realized that post-bloom temperatures can also affect fruit size at harvest.
As you train your high density orchards this spring, keep in mind some underlying components ("blueprint") for a successful intensive apple system.
There is some great information available for Christmas tree growers that could also be of interest to anyone managing conifers on landscape sites.
The Orchard Spray Record Spreadsheet has been updated for 2012 with 26 new pesticides and herbicides. This is an easy-to-use tool to help growers keep track of spray records with individual sheets for Apples, Peaches, Cherries and Pears. The spreadsheet is set up with drop-down lists for easier and faster completion. It will keep track of the various products used and maintain a cost summary.
This site provides users with identification and control options for numerous plants.
As explained at the orchard twilight meeting last week, we expected and found the first scab lesions today on non-sprayed check trees of Delicious, Golden Delicious, Cortland and Stayman.
Several cold temperature events before and during bloom occurred in 2012. This resulted in apple flower mortality, and there is also a possibility of some non-lethal injury to flowers and/or spur leaves. This leads to some uncertainty about the number and strength of initial fruit set.
I replied to my co-worker’s suggestion to write about mobile applications (Apps!) for tracking nutrition and fitness on smart phones and other devices with skepticism –would readers be interested?
Water testing by the natural gas industry in the Marcellus Shale region is affirming the need for all rural Pennsylvanians to regularly test their private water supply.
