Comparison of residual activity of pre‐emergence herbicides for control and seed production of multiple herbicide‐resistant Palmer amaranth in food‐grade white corn

Agrosystems, Geosciences & Environment
Nebraska is the number‐one producer of food‐grade white corn (Zea mays L.) in the United States. Food‐grade white corn has not been genetically engineered; therefore, non‐selective herbicides such as glyphosate or glufosinate cannot be used.

Determining if preemergent herbicide injury on ThryvOn cotton alters management strategies

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Glyphosate‐resistant Palmer amaranth (Amaranthus Palmeri S. Wats.) caused cotton growers to increase the use of preemergence (PRE) herbicides. These herbicides can cause crop injury, which increases the susceptibility window of cotton to thrips (Thysanoptera: Thripidae).

Development and Preliminary Evaluation of a Machine Vision‐Guided Smart Sprayer Prototype Toward Precision Vegetable Weeding

Journal of Field Robotics, Volume 43, Issue 3, Page 1973-1987, May 2026.
ABSTRACT Sustainable weed management necessitates herbicide‐reduced, precision weed control. Recent advancements in machine vision and artificial intelligence (AI) for weed recognition and localization have created new opportunities for high‐precision weeding. Although blanket spraying systems are widely used for weed removal, machine vision‐guided, AI‐

Overlapping Residual Herbicides for Control of Photosystem (PS) II- and 4-Hydroxyphenylpyruvate Dioxygenase (HPPD)-Inhibitor-Resistant Palmer amaranth (Amaranthus palmeri S. Watson) in Glyphosate-Resistant Maize

Frontiers in Plant Science, 2018
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 ...

Molecular Targeted Suppression of Male Fertility in Amaranthus palmeri S. Watson: Function and Layered Double Hydroxide Nanosheets‐Based Delivery System of ApmiR319

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3296-3307, May 2026.
ABSTRACT Amaranthus palmeri is one of the most troublesome invasive agricultural weeds worldwide, exhibiting super invasiveness and high resistance to conventional management strategies. Artificial microRNA‐mediated silencing technology, coupled with a nanoparticle‐mediated delivery system, represents an attractive approach for fertility control in A ...
