A Palmer amaranth (Amaranthus palmeri S. Watson) biotype has evolved resistance to photosystem (PS) II- (atrazine) and 4-hydroxyphenylpyruvate dioxygenase (HPPD)-inhibiting herbicides (mesotrione, tembotrione, and topramezone) in maize seed production field in Nebraska, USA. The objectives of this study were to determine the effect of soil residual pre-emergence (PRE) herbicides followed by (fb...

This invasive plant management study focuses on the treatment of younger and older seedproducing black cherry (Prunus serotina Ehrh.) individuals. We injected trees applied bark to thinner saplings in 2018. Over two vegetation periods, we studied effect 11 herbicides ranked treatments based their introduced foliage loss sprouting. In trunk injection experiment, most effective was a combination ...

When turfgrass stands are under renovation, a common problem is removing weeds prior to seeding because seedling turf does not emerge and compete well with that present. However, most herbicide labels recommend waiting for defined period of time seeding. If done the date prescribed on label, seed germination growth may be inhibited. A greenhouse study was conducted determine effects irrigation ...

Peer-reviewed research is not available to explain Polygonum aviculare L. (prostrate knotweed) control in Cynodon dactylon (bermudagrass) turf, yet P. common and troublesome managed C. turf. Six experiments were conducted determine options for golf roughs Hanover, VA. Studies evaluated hormone, photosystem, ALS inhibiting herbicides. Among a group of eighteen herbicide treatments, only six cont...
