Delaware Extension takes a close-up look at new noxious weeds for 2012

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.
