Wolfberry AgroDevCo is now seeking qualified, forward thinking growers to become part of the 2011 production and supply team.
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.
This material describes some of the features and challenges of the many marketing outlets available to farmers on the east coast.
The days are getting longer and signs of spring are everywhere you look. Here’s your spring wildlife calendar with information on what’s happening in the World of Wildlife.
The Pennsylvania Migration Count (PAMC) is an annual one-day snapshot of bird populations within our state. Which species are present, and where are they? How many are there? Do migratory patterns change from year to year?
Penn State Wildlife and Fisheries Science major James Feaga conducted research last summer on avian use of restored wetlands through the McNair Scholarship program.
Do you know which herbicides were used to manage weeds in forages before they were incorporated into a compost pile? If not, you may be in for a disappointing growing season.
On Saturday, April 16, 58 aspiring and beginning farmers from Virginia, Maryland, and across Pennsylvania flocked to “Breaking the Barriers”, a full-day Pennsylvania Farm Link and Penn State Extension co-hosted event at Delaware Valley College in Doylestown.
A new manual will help Pennsylvania growers identify, monitor, and control insect and disease pests affecting Christmas trees using integrated pest management (IPM).
Sweet corn growers are reminded to check the sensitivity of their sweet corn varieties before using Accent, Callisto, Laudis, or Impact herbicides.
Fire blight and apple scab models for locations throughout Pennsylvania are available at PA-PIPE. It is important to collect site-specific weather data in your orchards, but these models serve as a guide.
Got a question about growing small fruit? Chances are that someone else has the same question, but isn't asking! Send your question to Kathy Demchak, at 102 Tyson Bldg., University Park, PA 16802, or via email to email@example.com. You will be credited with the question, or can remain anonymous, as you wish. Today's question is about cyclamen mites on strawberries.
Pennsylvania tree fruit growers have embraced the principles of Integrated Pest Management (IPM) since the late 1960s and early 1970s. By one definition, IPM is the “utilization of all suitable techniques and methods in as compatible manner as possible and maintains the pest populations at levels below those causing economic injury.” The goal of IPM is to minimize the number and severity of perturbations in the agro-ecosystem while reducing the economic, environmental, and human health costs associated with the particular management option(s). Pennsylvania was one of the first states in the country to adopt the principles and practices of IPM in orchards by integrating the use of the black lady beetle Stethorus punctum – commonly referred to by most growers as the “black beetle” for the biological control of spider mites (e.g., European red mite and two-spotted spider mite). This program over the last 40 years was responsible for significantly reducing the number and amount of miticides used by fruit growers and reducing the severity of miticide resistance. More recently (2004 to present), the predatory mite, Typhlodromus pyri, has replaced Stethorus in many grower orchards as the principle biological control agent for spider mites in Pennsylvania.
Chronic wasting disease (CWD) was not found in samples taken from hunter-killed deer during the state's 2010 hunting season, according to Dr. Walt Cottrell, Pennsylvania Game Commission wildlife veterinarian. "We are pleased to report that Pennsylvania continues to have no confirmed or suspected cases of CWD in wild deer or elk," Cottrell said. "By conducting these tests from a random sample of hunter-killed deer and on all hunter-killed elk, we continue our efforts to find the disease in wild deer and elk in the state."
Sandea (halsulfuron-methyl, Gowan) has been approved for use on blueberries in Pennsylvania. Sandea has both preemergent and postemergent activity on certain weeds that can become problematic in blueberry plantings. Labeled rates are really low (1/2 to 1 oz/acre), so make sure that your application rate is correct. Be sure to follow precautions and directions on the label, and avoid contact with any green tissue.
