Q. Can you give us any tips on how to best sample strawberry leaves for a nutrient analysis, especially in the springtime on plasticulture? (paraphrased from a conversation with Tim Elkner, PSU Cooperative Extension, Lancaster County. He gets an “attaboy” for questions two months in a row!)
Just so folks are aware, we are monitoring for spotted wing drosophila in strawberries across the state. I don’t expect any large problems in this crop since strawberries ripen so early in the season, but this will alert us to any needed action before any potential problems get out of hand, and should serve as an early warning system for other crops in case the pest is present.
Angular leaf spot, caused by the bacterium Xanthomonas fragariae, seems to be problematic in numerous strawberry plantings this spring. This disease is favored by cold, wet conditions, so given the weather we’ve had across the state this spring, it’s no surprise that we are seeing problems. The bacteria get spread within a planting by splashing of water droplets. Needing to use overhead irrigation for frost protection can make the problem worse.

As fruit growers brace for another year of infestations by the brown marmorated stink bug, Penn State researchers have released a Web-based tool that they hope will help enhance their understanding of this invasive insect pest. Developed in collaboration with the Pennsylvania Department of Agriculture, the mapping tool is embedded in a website found at http://stinkbug-info.org/ online.

Litter and dumping in Pennsylvania continues to be an issue effecting water quality.
In Spring, nuisance and damage conflicts can happen between people and wildlife. Voles, moles, chipmunks, rabbits, and woodpeckers can all create headaches for homeowners and gardeners.
The relative toxicity of individual leaves is low–horses must consume hundreds of pounds to experience ill effects. However, bracken fern is unique among the toxic plants in that some horses seem to develop a taste for it and will seek it out even when other forages are available.
Vegetable growers now have another tool in their toolbox. Kanemite, a miticide from Arysta LifeScience is now labeled for fruiting vegetables (tomatoes, peppers, eggplants, etc.) and edible podded beans.

Through the support of PVGA, the 2011 sweet corn trapping network has distributed 2,150 pheromone lures and 100 Vaportapes among 20 Extension Educators, to create weekly dataflow from ~49 farms, using a biweekly pheromone replacement rate over a 14-15 week season. It’s truly a cooperative effort that provides a first cut of the pest pressure from corn earworm, fall armyworm, and both the E- and Z- pheromone race of European corn borer.
The first scab symptoms at the Penn State Fruit Research and Extension Center in Biglerville were observed May 2 on Rome Beauty. Based on the New Mills Apple Scab Disease Model, apple scab infection periods occurred April 1, 3-4, 10-13, 16-17, 19-20, 22-24, 28 and May 2-3. As a result of the extended wetting periods, growers who have not used a DMI fungicide on apples this season should consider using one at bloom or petal fall. Due to moderate resistance to these products, be sure to use the higher rates allowed on the label.
First bloom on apple trees at the Penn State Fruit Research and Extension Center in Biglerville was April 25. Based on the MaryBlyt Prediction Program and Campbell Scientific Weather Data Systems, the risk of fire blight was severe on April 25-28.
Based on an infection model adapted from the APS Compendium of Apple and Pear Diseases, Cedar Rust Infection Periods at the Penn State Fruit Research and Extension Center in Biglerville were April 1, 3-5, 8-13, 16-17, 19-20, 22-24, and 27-28.
Each year, Penn State Extension Water Resource Educator, Jim Clark, prepares educational material to help the students who compete in the Pennsylvania Envirothon in North Central Pennsylvania understand the “Current Environmental Issue”.
Cool, wet spring weather has given us few good days to do field work, increasing temptation to work soils when they are still too wet. Resist that temptation if at all possible. Our soils are more susceptible to compaction than most. Working when soils are too wet can cause surface compaction in the topsoil layer that lasts throughout the current growing season, and deeper subsurface compaction that lasts for many years.
