Subgenomic Distribution and Herbicide Cross-Resistance of <i>ALS</i> Gene Mutations in Allohexaploid <i>Echinochloa crus-galli</i>. [PDF]

Plant Direct
ABSTRACT Herbicide target site resistance in polyploid species is more complex than in diploids due to potential subgenome interactions. This study characterized mutations in the ALS gene across distinct subgenomes of hexaploid Echinochloa crus‐galli and evaluated the cross‐resistance patterns conferred by each mutation to various ALS‐inhibiting ...

Stacked mutations in multi-copy AHAS genes enhance sulfonylurea herbicide resistance in soybean. [PDF]

Plant J
SUMMARY Weeds are a major factor that negatively impact crop yields. Developing herbicide‐resistant germlines is crucial for efficient weed control. Sulfonylurea‐ and pyrimidinyl benzoate‐based herbicides inhibit the function of acetohydroxyacid synthase (AHAS), a key enzyme in the biosynthesis of branched‐chain amino acids in plants. To create soybean

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%.

Genetic diversity and population structure of ALS-resistant Amaranthus hybridus across Brazil's primary soybean-growing regions. [PDF]

Pest Manag Sci
We identified two distinct target‐site mutations, Asp‐376‐Glu and Trp‐574‐Leu, that confer resistance to acetolactate synthase inhibitors in Amaranthus hybridus populations across Brazil's soybean‐growing regions. These findings suggest multiple independent origins of resistance, with its spread primarily driven by local herbicide selection pressure ...

An Urban Stormwater Contaminant Signature: Defining Priority Contaminants for Urban Stormwater Research. [PDF]

Water Environ Res
We identified a core suite of frequently detected contaminants in urban stormwater ponds using three complementary sampling methods. This urban stormwater contaminant signature (USCS) highlights cumulative exposures in pond ecosystems and supports more targeted monitoring of urban runoff.

Efficacy of post-emergence herbicide imazethapyr for weed management in different mungbean (Vigna radiata) cultivars

The Indian Journal of Agricultural Sciences, 2014
Three mungbean cultivars, viz. ML 267, ML 818 and PAU 911 showed good degree of tolerance to imazethapyr sprayed at different doses and at different times during 2008 and 2009.
