Grasshoppers, Japanese Beetles and Aphids are showing up now but pressure from diseases appears low thus far.
Pharmaceuticals in surface water such as lakes and streams are a growing concern. They can cause developmental and other health issues in aquatic life. Scientists have largely considered treated wastewater that's released into the environment as the main source. Now researchers reveal other possible sources.
The Penn State Extension Water Team has been educating private water well owners about water and their health for years. This year several counties have been identified to receive no cost, private water supply, test kits, all associated with health parameters, such as lead.
Researchers have found that larval fish exposed to microplastic particles during development displayed changed behaviors and stunted growth which lead to greatly increased mortality rates. The researchers discovered that larval perch that had access to microplastic particles only ate plastic and ignored their natural food source of free-swimming zooplankton.
In the U.S., approximately 60 percent of oil underground is inaccessible through conventional recovery methods, but through a new $1.3 million grant from Abu Dhabi National Oil Company (ADNOC), Russell Johns, professor of petroleum and natural gas engineering, is developing improved methods to free the once-trapped fossil fuel (more...)
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.
The latest information that growers need to know for apple scab, fire blight, sooty blotch and flyspeck, rots, bacterial spot, and cherry leaf spot.
The Tree Fruit Pathology Lab at FREC is seeking fire blight samples again this season from around the state of Pennsylvania in commercial orchards and home landscapes for evaluation for antibiotic-resistant strains of the bacteria and other projects. If you have fire blight present in your orchard/yard, please contact Dr. Kari Peter for instructions for sampling.
July is usually a good month to assess the results of early season insect pest management practices and to make sure nothing will be missed for the remaining of the season. Early July also marks the beginning of a much higher pressure from brown marmorated stink bug nymphs and summer adults.
Spotted wing drosophila has been found in very low numbers in the Mid-Atlantic and Northeast, so it’s time to be watching for spotted wing drosophila presence in raspberries, blueberries, and other thin-skinned fruit. A few Pennsylvania growers reported finding larvae in late-season strawberries.
Tips to eating wisely when celebrating the Fourth of July utilizing the US Dietary Guidelines and MyPlate.
We all get a little rusty as we get older, but one thing that we don’t want to see getting rusty is our brambles. There are several rust diseases that affect brambles. I’m just going to focus on orange rust, which is the most important rust disease in the northeast. We are definitely seeing a bit of orange rust this year, with the cool wet springs. You’ll see this disease on blackberries, black raspberries and purple raspberries. Orange rust does not affect red raspberries.

Yesterday downy mildew was confirmed in Caroline County, MD in a commercial cucumber field.
In May 2016, an aggressive form of black leg caused by the bacterial pathogen Dickeya dianthicola was confirmed in a potato seed lot being grown in New Jersey. This is the same pathogen that caused widespread yield losses across the region in 2015 when it was first confirmed in the U.S. It subsequently has been detected and confirmed in DE, PA, MD and VA this season. Pectobacterium atrosepticum which has long been associated with blackleg has also been detected.
Over the past several years, bacterial diseases have become an increasing problem in tomato and pepper fields across Pennsylvania. Last year it was tomato while this year is seems to be more on pepper depending on where you are in Pennsylvania.
