When it comes to managing fire blight, the first line of defense is good sanitation, which is removing the overwintering source for the bacteria: cankers. Understanding what a canker is, being able to identify them in orchard, the importance of removal, and pruning strategies are discussed.
Revised every two years with input from Penn State faculty members, extension specialists and other consultants, this nearly 400-page production guide provides commercial fruit growers, extension educators, consultants, and others with the newest information on fruit culture, orchard nutrition, spraying, pesticides, storage of tree fruit crops, marketing, and management of weeds, insects, diseases and more.
Unlike some flowering landscape trees, peaches, cherries, apples and pears originated in a temperate climate, similar to our own. They are well-adapted to our climate, even in an el Niño year. Most fruit trees went dormant this fall, and stayed dormant. Fruit trees begin to go dormant in response to shortening day length in the fall. Exposure to freezing temperatures accelerates the onset of dormancy. Although this past fall was warmer than usual, the fruit trees got the necessary signals and went into dormancy.
Research performed by universities is relatively expensive because we have to pay for the considerable infrastructure associated with research, including the salaries of trained researchers and technicians. Recently some growers have expressed a desire to perform their own research to save money.
Although the earth is warming as a whole as a result of climate change, the weather is also becoming more variable resulting in early-winter cold snaps, winter thaws followed by extreme cold events, and early spring bloom followed by frosts.
The Ag Entrepreneurship team has developed a series of Learn Now Videos for new, young and minority growers. The goal is to increase next generation skills in identifying appropriate markets for their farm-fresh and value-added horticultural products.
Penn State graduate students and visiting scientists from other institutions play a critical role in many studies conducted at Penn State's Fruit Research and Extension Center in Biglerville, Adams County. And now, thanks to the financial support of the State Horticultural Association of Pennsylvania, new graduate-student housing at the center will help ensure those contributions into the future.
“Tracking the Brown Marmorated Stink Bug” shows growers and others how to identify BMSB, why this pest is important in agriculture, and what’s at stake if we don’t stop it. Four new installments bring important new information about integrated pest management or IPM in terms of biological control, monitoring and trapping, and the iconic pyramid traps. These new videos show just how far our team has come in understanding this peculiar and pernicious creature, and why the newly hatching Trissolcus insect, now in the wild, could change the game.
Keeping honeybees healthy has become a challenge for beekeepers. One main reason is a threat that has been wiping out bees since the late 1980s: the varroa mite. But one beekeeper in PA might have a solution: raising bees that demonstrated a unique, mite-fighting grooming behavior.
It’s the time of year when many growers are figuring out what varieties to include in their strawberry orders. For an impartial view of the performance of some of the newer cultivars, here are the first harvest year results from a matted-row trial at the Penn State Horticulture Research Farm at Rock Springs.
As the true winter season approaches—officially arriving on December 21st at 11:48 PM EST, it might be good to look back on this year’s growing season. There have been extremes of temperatures and moisture the past two years.
Apples are a long-lived perennial crop, thus most fruit farms have several blocks of trees that vary in age and size. Many orchard enterprises have adopted intensive (≥518 trees per acre) orchard systems over the past 25 years. However, blocks of larger semi-dwarf trees at medium density still exist on many farms, and often these blocks still have a significant role to play in the orchard enterprise.
The spotted lanternfly has now been found in one additional municipality in Berks County; an additional township in Montgomery County and has appeared in parts of Bucks and Chester Counties. The additional quarantined municipalities include Boyertown Borough, Berks County; Douglass Township, Montgomery County; Milford Township including Trumbauersville Borough, Bucks County; and South Coventry Township, Chester County.
Firewood is an important source of heat for many Pennsylvania residents. As the weather turns colder, a lot of folks are gathering firewood for the winter. Unfortunately, firewood is also an important source of invasive problems, and moving it around can spread damaging insects and diseases. You should use local firewood as much as possible.
Growers can get a jump on fungal and bacterial disease management for the 2016 season this fall. A review of tips to manage apple scab, fire blight, peach leaf curl, cherry leaf spot, bacterial canker, and fungal fruit rots are discussed.
Broad mite (Polyphagotarsonemus latus) has been a pest of tropical, subtropical and greenhouse crops for over a century, and has been problematic for pepper growers in PA for the last couple of years. Now we can add blackberries to the list of crops that they frequent.
The Penn State Extension Horticulture, Start Farming, and Pesticide Education Teams have produced three new videos on integrated pest management practices for sustainable establishment and management of apple orchards.
For years we have all heard the landscape green industry say that "fall is for planting". As orchardists, we should consider that fall is a very good time for applying weed control materials.
Zeus Prime XC is a new product from FMC Corporation with a new active ingredient that has not been used in tree fruit before. Currently it has a supplemental label for use in apples that have been established for at least 3 years—similar to the time frame for Alion.
The National Center for Farmworker Health has created a guide for agricultural workers that describes benefits under the Affordable Care Act. The guide is in English and is available for sharing.
