More than 300 people attended an update meeting about the invasive insect, the spotted lanternfly, on October 27, 2016 in Bally, PA.
A timeline of actions to take in the management of the spotted lanternfly.
Black medic (Medicago lupulina) is a spreading, low growing summer annual.
Indiscriminate use of phosphorus-containing fertilizer on runoff-prone turfgrass sites is thought to contribute to contamination of ground and surface water (Soldat and Petrovic, 2008).
Birdseye pearlwort (Sagina procumbens) is a perennial plant that often forms dense mats in a landscape, particularly in turf. It can tolerate low mowing and because it has erect stems, it can take on the appearance of a turfgrass or moss.
Multiflora rose (Rosa multiflora) is an invasive, non-native woody plant that can grow up to 9 feet tall and with a similar width. It was brought to the United States to use as rootstock for other roses and as a “living fence” to prevent soil erosion. However, like many invasive species, it escaped from managed care and is now naturalized.
The summer of 2016 has proven to be one of the most difficult years to keep grass alive (let alone healthy) in recent memory. Some areas of Pennsylvania are still under a drought watch or warning, while a few areas have received timely rains. Hopefully you are one of the lucky ones, but most of us are faced with powder-dry soil, brown turf, and significant turf loss.
The PA Department of Agriculture recently confirmed boxwood blight in a residential setting. The infected material has been removed and destroyed.
Employers must often keep up with a variety of required government posters at their orchards, farms, or other places of business which can be daunting at times. Earlier this month, the U.S. Department of Labor changed two posters that employers are required to post in the workplace.
The spotted lanternfly is an invasive insect that was first found in Pennsylvania in 2014.
Perhaps you have seen this wasp flying over the landscape at about 12” above the ground circling in a mass of its fellow wasps. What is it doing? Well they are selecting mates and mating, prior to laying eggs on grubs in the landscape.
At first glance it may appear as if someone has whitewashed your landscape ornamentals. But upon closer examination with a hand lens you should notice the white hyphal growth that confirms the presence of the disease known as powdery mildew. Powdery mildew is a common disease that begins to appear in mid-to-late summer in Pennsylvania on a wide array of woody ornamentals.
Purple loosestrife (Lythrum salicaria) is an invasive, non-native herbaceous perennial plant that can grow up to 6 feet tall. This plant is invasive in the sense that it forms large colonies in wetlands, marshes and along streams.
By now we all know Monarch butterflies flock to Milkweed. And if you have been caring for Milkweeds planted for the Monarchs you have noticed that a lot of other insects find these plants appealing as well.
In late 2015 the Environmental Protection Agency issued the long awaited revision to the Worker Protection Standard (WPS). Although it is now technically active it will not be enforced until 2017 but the original WPS will still be enforced until the end of 2016. Please keep in mind that the WPS covers both restricted use AND general use pesticides. This article will deal with the highlights to the revision but also some areas of the current WPS that need emphasized.
