Improving Weed Management Based on the Timing of Emergence Peaks: A Case Study of Problematic Weeds in Northeast USA

Frontiers in Agronomy, 2022
We reviewed the timing of the peak rate of emergence for 15 problematic weed species as well as ways to use this knowledge to improve control. Much of the previous literature modeled emergence based on growing-degree-days.

An Evaluation of Herbicides for Broadleaf-Weed Control in Rapeseed: Efficacy, Phytotoxicity, and Soil Persistence Studies [PDF]

, 1984
At the recommended rates (1.0 lb/A for trifluralin, ethalfluralin, EL5261; 0.75 lb/A for dinitramine; 1.2 lb/A for nitrofen), none of the herbicides we evaluated in these studies reduced rapeseed stands, yields, or test weights. However, at higher rates (

Differential response of Palmer amaranth (Amaranthus palmeri) seed germination and seedling emergence under variable environmental conditions

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Palmer amaranth (Amaranthus palmeri S. Watson) is a eudicot weed that is considered as one of the most problematic weed species. It is reported to overcome several environmental and management stresses under field conditions. Research was conducted in a growth chamber and greenhouse to evaluate the effects of different stress parameters such ...

Dose-response of common lambsquarters, redroot pigweed, and foxtail species to pyroxasulfone plus encapsulated saflufenacil applied preemergence to corn

Weed Technology
In September 2024, BASF Canada introduced a new premixture of pyroxasulfone and encapsulated saflufenacil to control weeds in corn production. Limited research has been conducted to determine the biologically effective dose of this new premixture for the

Genetic structure of Cercospora beticola populations on Beta vulgaris in New York and Hawaii

Scientific Reports, 2017
Cercospora leaf spot (CLS), caused by Cercospora beticola, is a major disease of Beta vulgaris worldwide. No sexual stage is known for C. beticola but in its asexual form it overwinters on infected plant debris as pseudostromata, and travels short ...

Identifying and managing Cercospora leaf blight in soybean: From scouting to best management practices

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Maximizing soybean [Glycine max (L.) Merr.] yield requires effective management of Cercospora leaf blight (CLB), a significant foliar disease that can reduce productivity and grain quality. The impact of CLB is particularly notable in regions such as the mid‐southern United States, where species of Cercospora, predominantly C. cf. flagellaris,

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‐

Pervasive weed management and soybean yield with 2,4-D and glufosinate applied alone, mixed, or sequentially

Weed Technology
Field experiments were conducted near Beresford and South Shore, South Dakota, in 2023 and 2024, to determine weed control and soybean yield with 2,4-D and glufosinate applied individually, together, and sequentially. Herbicides were sequentially applied
