Efficacy of HPPD-inhibiting herbicides applied preemergence or postemergence for control of multiple herbicide resistant waterhemp [Amaranthus tuberculatus (Moq.) Sauer] [PDF]

Canadian Journal of Plant Science, 2019
Research was conducted in 2017 and 2018 to determine the relative efficacy of five HPPD-inhibitors, tank-mixed with atrazine, for the control of multiple herbicide resistant waterhemp. At 12 wk after application (WAA), isoxaflutole + atrazine, mesotrione + atrazine, and tembotrione + atrazine, applied preemergence (PRE), controlled waterhemp 90%, 87%,

Effects of Long-Term Cover Cropping on Weed Seedbanks

Frontiers in Agronomy, 2020
Cool-season cover crops have been shown to reduce soil erosion and nutrient discharge from maize (Zea mays L.) and soybean [Glycine max (L.) Merr.] production systems. However, their effects on long-term weed dynamics are not well-understood. We utilized

Comparative transcriptomic analysis of males and females in the dioecious weeds Amaranthus palmeri and Amaranthus tuberculatus

, 2023
Waterhemp (Amaranthus tuberculatus (Moq.) Sauer) and Palmer amaranth (Amaranthus palmeri S. Wats.) are two dioecious and important weed species in the USA that can rapidly evolve herbicide-resistance traits. Understanding these two species' dioecious and
