Sorghum tolerance and weed control with amicarbazone and metribuzin applied preemergence

Agrosystems, Geosciences & Environment
Groundwater contamination has prompted the Environmental Protection Agency to consider restricting atrazine use, highlighting the need for alternative preemergence herbicides in grain sorghum (Sorghum Moench).

Diminishing weed control exacerbates maize yield loss to adverse weather. [PDF]

Glob Chang Biol, 2021
Individually, adverse weather and weed interference cause significant maize yield losses; however, the combined effects of the two on maize is poorly understood. Using machine learning techniques on a database of herbicide trials spanning 27 years, we identified poor late‐season weed control, high temperatures, and low water availability during silking

Impact of volatility reduction agents on dicamba and glyphosate spray solution pH, droplet dynamics, and weed control. [PDF]

Pest Manag Sci, 2023
Dicamba and glyphosate spray solution pH, droplet dynamics (size and velocity), and weed control as impacted by recent federally mandated volatility reduction agents (VRAs) were evaluated across a broad geography. Abstract BACKGROUND Regulations in 2021 required the addition of a volatility reduction agent (VRA) to dicamba spray mixtures for ...

Pest categorisation of <i>Pantoea ananatis</i>. [PDF]

EFSA J, 2023
Abstract The EFSA Plant Health Panel performed a pest categorisation of Pantoea ananatis, a Gram‐negative bacterium belonging to the Erwiniaceae family. P. ananatis is a well‐defined taxonomic unit; nonetheless, its pathogenic nature is not well defined and non‐pathogenic populations are known to occupy several, very different environmental niches as ...

Deep learning-based laser weed control compared to conventional herbicide application across three vegetable production systems. [PDF]

Pest Manag Sci
In 2024, trials in New Jersey and New York evaluated the effectiveness of laser weeding with a Carbon Robotics unit compared with herbicides on beets, spinach, and peas. Results demonstrated that laser weeding was as effective or superior to herbicides in controlling weeds, reducing biomass by ≥97% and boosting crop growth by ≥30%.

Interspecific variation in persistence of buried weed seeds follows trade-offs among physiological, chemical, and physical seed defenses. [PDF]

Ecol Evol, 2016
Improved understanding of factors driving variation in persistence of weed seeds in soil seedbanks is needed to support more effective management approaches. We quantified interspecific trade‐offs among physiological, chemical, and physical traits of weed seeds and their persistence in the soil seedbank in a common garden study.

Cover crops and residual herbicides reduce selection pressure for Palmer amaranth resistance to dicamba‐applied postemergence in cotton

Agronomy Journal, Volume 113, Issue 6, Page 5373-5382, November/December 2021., 2021
Abstract The most widely planted cotton (Gossypium hirsutum L.) and soybean [Glycine max (L.) Merr.] varieties in the United States are resistant to the herbicide dicamba. Measures to reduce selection pressure for dicamba‐resistant weeds is paramount. Four studies evaluated strategies to reduce selection pressure for Palmer amaranth (Amaranthus palmeri

Evaluation of corn herbicide programs with and without atrazine

Crop, Forage &Turfgrass Management, Volume 7, Issue 2, 2021., 2021
Abstract Atrazine is a foundational herbicide in corn (Zea mays L.) because of its broad‐spectrum weed control and utility for pre‐emergence or postemergence applications. Extensive atrazine use has led to traces in groundwater, surface water, and aquifers. This research explored corn herbicide regimes with little or no atrazine.

Evaluation of thiencarbazone‐methyl for use in acetolactate synthase‐resistant soybean

Crop, Forage &Turfgrass Management, Volume 6, Issue 1, 2020., 2020
Abstract To combat herbicide‐resistant weeds, new options are needed to effectively rotate herbicide modes of action and slow the development of additional herbicide resistance. Thiencarbazone‐methyl (TCM), an acetolactate synthase (ALS)‐inhibiting herbicide, is currently being evaluated for preemergence (PRE) and postemergence (POST) activity on many ...

Growth and mineral nutrition Of Ipomoea quamoclit Crescimento e nutrição mineral de Ipomoea quamoclit

Planta Daninha, 2009
A greenhouse experiment was carried out from November 2006 to April 2007 at FCAV/UNESP, Brazil, aiming to study the dry mass production and the accumulation and distribution of macronutrients in Ipomoea quamoclit, an important weed for annual and ...
