Selectivity of Chlorimuron-Ethyl to Castorbean Crops [PDF]

Planta Daninha, 2017
: Castorbean presents high sensitivity to competition; therefore, it is necessary to develop alternatives for the weed management, mainly for the chemical control of eudicotyledons species.

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 ...

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

Associations of Specific Pesticides and Incident Rheumatoid Arthritis Among Female Spouses in the Agricultural Health Study. [PDF]

Arthritis Rheumatol
Objectives Growing evidence suggests farming and agricultural pesticide use may be associated with rheumatoid arthritis (RA), but few studies have examined specific pesticides and RA among women living on farms, who may personally use pesticides or may be indirectly exposed.

Monitoring the temporal changes in herbicide‐resistant Amaranthus tuberculatus: a landscape‐scale probability‐based estimation in Iowa

Pest Management Science, Volume 79, Issue 12, Page 4819-4827, December 2023., 2023
The survey assesses the evolution of herbicide resistance on Amaranthus tuberculatus over a 6‐year period in Iowa. Fields were probability‐based and randomly selected which is unique to other weed surveys. Abstract Background A landscape‐scale probability‐based sampling of Iowa soybean [Glycine max (L.) Merr.] fields was conducted in 2013 and 2019 ...

Genetic basis and origin of resistance to acetolactate synthase inhibitors in Amaranthus palmeri from Spain and Italy

Pest Management Science, Volume 79, Issue 12, Page 4886-4896, December 2023., 2023
Genetic analyses revealed that acetolactate synthase‐resistant Amaranthus palmeri populations from Italy and Spain originated from independent introduction events and then spread over short and long distances via seed dispersal. Abstract BACKGROUND Amaranthus palmeri is an aggressive annual weed native to the United States, which has become invasive in

Volunteer rapeseed infestation and management in corn

Agronomy Journal, Volume 115, Issue 6, Page 2925-2937, November/December 2023., 2023
Abstract The study was conducted to evaluate the effect of different termination timings for rapeseed (Brassica napus L.) cover crop on biomass production, termination efficiency, and volunteer infestation in the successive cash crop (corn, Zea mays), and control of volunteer rapeseed with herbicides.

A follow‐up survey to assess stakeholders’ perspectives on weed management challenges and current practices in Nebraska, USA

Agrosystems, Geosciences &Environment, Volume 6, Issue 3, September 2023., 2023
Abstract Stakeholders across the state of Nebraska, USA, were surveyed in 2019–2020 to assess problem weeds and weed management practices in agronomic crops. A total of 420 complete responses were obtained across four Nebraska districts (Northeast, Panhandle, Southeast, and West Central).
