Because of the increasing number of glyphosate-resistant weeds, alternate herbicide-resistant crops and herbicides with different modes of action are required to protect crop yield. Glufosinate is a broad-spectrum POST herbicide for weed control in glufosinate-resistant crops, including soybean. The objective of this study was to compare herbicide programs with glufosinate applied singly at lat...

The velvetleaf (Abutilon theophrasti Medik.) is a strong and competitive weed in fields that inhibits the growth of crops. Reports have suggested allelopathy one reasons for this inhibition; however, mechanism remains unclear. In study, powder/extracts were shown to inhibit seed germination, yield maize, wheat soybean through petri dish, pot field control experiments. We observed concentration-...

Dicamba plus glyphosate tank mixture have been largely adopted for postemergence weed control after the development of dicamba-tolerant crops. Ammonium sulfate is commonly used as water conditioner (WC) to increase efficacy, but its use restricted dicamba herbicides. The non-AMS and other adjuvants could be a way optimize efficacy this while mitigating herbicide off-target movement. objective s...

Abstract Tolpyralate is an herbicide that usually mixed with atrazine for broad-spectrum weed control in corn. Previous research has provided information on the effective dose (ED) of tolpyralate applied alone and a 1:33.3 mixture atrazine; however, commercially at 30 to 40 g ai ha −1 minimum 560 atrazine. Therefore, five field trials were conducted over 3 yr (2019 2021) determine ED complement...
