Palmer amaranth and Texas Panicum added to Delaware Department of Agriculture’s Noxious Weed List
In 2012. two noxious weeds were added to Delaware’s Noxious Weed list – Texas panicum and Palmer amaranth. In an effort to increase awareness of these troublesome and costly weeds, the Delaware Department of Agriculture arranged for a media opportunity to record, interview and photograph resource material at the Thurman G. Adams Research Farm located at the Carvel Research and Education Center in Georgetown.
The following images were taken on August 31, 2012 by the University of Delaware and may be freely used in media articles or footage or for educational purposes. It is the expressed purpose of media attention to raise awareness and identification of these weeds to benefit Delaware agriculture. Please attribute photos when possible to University of Delaware Cooperative Extension.
“Most growers aren’t aware they have these weeds” VanGessel said.
Because of their rapid growth and aggressive nature, these weeds can overtake fields and can result in a 25% reduction in yields by competing for sun, water and nutrients. If allowed to grow tall, their canopy can create sun blocks for crops. In some cases, the weeds overtake a field to the level that they are abandoned by the farmer/grower. Texas panicum and Palmer amaranth now join giant ragweed, Canada thistle, burcucumber, and johnson grass as members of Delaware’s noxious weed list. Weeds are added to the list after careful review of other regions, evaluation observations by UD and DDA weed specialists and input from Delaware growers. Landscape weeds are not part of the criteria – the six noxious weeds are so named for their impact on production agriculture.

2012 Summer Turf and Nursery Expo well attended at UD’s Carvel Center in Georgetown
For farmers and landscapers in the Delmarva region, 2012 has been a difficult and frustrating year. A dry winter, and sustained heat and drought during spring and summer – critical growth periods – have left challenging conditions for anyone working in the agriculture or horticulture industries. Throughout Delaware, crops, ornamental trees, shrubs and lawns have shown signs of stress, leaving them vulnerable to pests, weather-induced damage, or stress-related death.
A picture perfect day welcomed more than 140 exhibitors, presenters, DNLA and Extension experts and industry professionals who appreciated seeing real-time examples in actual field and landscape settings.
“This is a great refresher course on common insects and problems we all have,” says Aaron Jackson, nursery supervisor at Tunnell Companies. “We get to see it in person and have professionals tell us what we are looking at.”
Local landscapers agreed. “The University of Delaware provides a lot of resource materials, but it is good to see working or field information” said Sue Manlove, who with her husband Larry, own and operate Manlove Lawn and Landscape Company in Seaford. “It adds a whole different dimension seeing it in person,” offered Larry Manlove.

A variety of sessions were available to landscapers, horticulturists, and related industry professionals. A crew from EP Henry provided a demonstration on using pavers in the landscape and for raised beds. A take down of an overgrown Chinese Paulownia tree provided an opportunity for Sussex Tree, Inc., to explain when tree removal should be handed over to an experienced pro. Techniques in chain saw operation and best safety practices were emphasized.
Outdoor classroom venues included the Sussex County Master Gardener’s Demonstration Garden, a new Integrated Pest Management (IPM) educational ornamental section, and trees and shrubs planted around the Carvel Center – each providing diverse examples of common landscape situations that Extension educators other presenters used at the Expo as teaching tools.
At a stop along his insect tour, Brian Kunkel pointed to bagworm cases that appeared on Crape Myrtles, Junipers and inanimate objects such as a brick wall and steel and PVC piping. Kunkel said timing was critical for bagworm control, adding that by the time cases are brown or grey, it is often too late to for spraying.
Cooperative Extension specialist and entomologist Brian Kunkel led a morning and afternoon tour, identifying both beneficial insects and pests commonly found in Delaware landscapes, and suggested control strategies and examples where no measures are necessary. IPM strategies emphasize the use of beneficial insects and parasitoids, which can effectively control damaging pests without the use of pesticides
Richard Pratt, state arborist with the Hagley Museum and Gardens partnered with UD Extension’s Dot Abbot and reviewed proper planting and pruning techniques for trees. Delaware State Police Cpr/3 Keith Lamey conducted a session on the laws and regulations regarding commercial transport and the nuances between being classified as intra or inter – state business and provided guidance on commercial road safety.
In addition to landscapers, several state agencies were represented including the Delaware State Parks and Delaware Departments of Agriculture and Transportation. Rose Ogutu, an Extension specialist with Delaware State University, taught a session on soil health.
“To Delaware’s green industry, Cooperative Extension means top-notch researchers, educators and facilities,” said Valann Budischak, executive director of DNLA. “They keep us up to date on the latest practices and products and allow us to partner in some of their research projects.”
Michelle Rodgers, associate dean of UD’s College of Agriculture and Natural Resources and director of Cooperative Extension was impressed with the variety of practical sessions offered to the participants. “It is great to be in partnership with DNLA in order to share knowledge and expertise for Delawareans.”
On August 1, 2012, 44 youth, all children of temporary migrant workers who are employed during the summer in the agricultural sector in Kent and Sussex County, were treated to a Ag Safety Day Camp, a full day of extracurricular activities organized by Delaware Cooperative Extension Safety Agent Mike Love, and his team of volunteers from Sussex Central High School FFA. The day was part of a six week summer program developed to promote academic, safety and other learning experiences for children of temporary migrant workers who travel throughout the country.
Children of migrant workers may be exposed to various farm equipment – This program teaches them how to be careful around specialized machinery.
Wednesday’s day trip to the Carvel Research and Education Center included several educational demonstrations or “classes” so that children could have the opportunity to enhance their safety skills in different environments that they encounter. Because many of the program’s children live on Delaware farms, agricultural equipment was an emphasis for the day.
Children arrived with their teachers from Eagle’s Nest and Milford Boys and Girls Club and watched demonstrations on child safety restraints and their proper use, air bag deployment, chemical and ATV safety, safety around water, and safe practices around a variety of home and farm equipment. While the primary purpose of the federal program concentrates on academics, the summer day trips, such as this safety exposition, reflect common and practical scenarios that the children encounter in their day – to-day lives on the farm and on the road.
Maria Mendoza, field agent and migrant advocate from the Delaware Department of Education explained the value of their visit with Cooperative Extension. “These children are on the road a lot, traveling from state to state.” says Mendoza. “Typically these children are in Delaware with their families during the growing season from June to August.”
In 2012, Delaware Department of Agriculture added Palmer amaranth, Amaranthus palmeri to its list of noxious weeds. Not only is the troublesome weed resistant to herbicides, it is a prolific seed producer, with each plant responsible for an average of half a million seeds. Unattended, the weed can quickly overtake a crop.
Extension Agent Emmalea Ernest, when not breeding lima beans, is defending them against the noxious weed Palmer amaranth
Palmer amaranth – one of six noxious weeds named by the Delaware Department of Agriculture’s Noxious Weed Program
Palmer amaranth isn’t shy about taking root in the vegetable trial plots located at the Thurman G. Adams Research Farm, part of the University of Delaware Carvel Research and Education agriculture experimental station.
For two days in August, and with man hours anticipated, it takes a village – a community of Extension hands – specialists, agents, students and summer employees to do what must be done, bend over and hand remove each plant. It’s old fashioned work, but the labor is an effective preventative measure.
“I estimate we’ve prevented billions, billions by hand removal,” says Emmalea Ernest, an Extension agent who spent about an hour this particular morning in a lima bean field with three summer employees, Heather Baker, Abby Atkins and Danielle Vanderhei, yanking up the culprit weed. Palmer amaranth’s seeds are not airborne, and most commonly spread through agricultural and mowing equipment.
This particular plot, which Ernest estimates is nearly an acre, will take an a few more hours to get under control. “Fortunately, they are not deep rooted and are easy to pull up.”
Ernest said that Palmer amaranth, like most weeds, “reduces yields as it competes with the crop for water, sunlight and nutrients. If uncontrolled it would also make harvesting in that field very difficult.”
