RNAi technology development for weed control: all smoke and no fire? [PDF]

Pest Manag Sci
Despite the potential of Spray‐Induced Gene Silencing in weed management several critical points such as molecular target, weed species of interest as well as delivery techniques need to be addressed. Abstract RNA interference (RNAi) technology, specifically Spray‐Induced Gene Silencing (SIGS), holds potential as an innovative approach for selective ...

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.

Soil fertility characteristics in North Carolina pastures as affected by spatial separation and renovation with annual forages

Agronomy Journal, Volume 115, Issue 1, Page 384-394, January/February 2023., 2023
Abstract Spatial variation in soil properties is often considered significant across broad geographical regions due to soil formation factors. However, fine‐scale variations might also be significant. This study was conducted with the original intent of assessing how simple and complex mixtures of annual forages might be used to renovate perennial ...

Genetic variation for seed retention in accessions and genotypic lines of perennial ryegrass (Lolium perenne L.)

Crop Science, Volume 63, Issue 1, Page 306-319, January/February 2023., 2023
Abstract Seed shattering is a key constraint to improvement of seed yield in perennial ryegrass and, as a result, seed retention is an essential trait for breeding of this valuable crop. It is unclear whether sources of seed retention are available to plant breeders.

The intensity of non-target site mechanisms influences the level of resistance of sourgrass to glyphosate [PDF]

, 2014
Non-target site mechanisms are involved in the resistance of sourgrass (Digitaria insularis) to glyphosate. Studies on the 14C-glyphosate absorption and translocation as well as the detection of glyphosate and its metabolites in sourgrass plants were ...

Unraveling the Mechanism of Resistance in a Glufosinate-resistant Palmer amaranth (\u3ci\u3eAmaranthus palmeri\u3c/i\u3e) Accession [PDF]

, 2022
Glufosinate resistance in Palmer amaranth (Amaranthus palmeri S. Watson) was recently detected in three accessions from Arkansas, USA. Amaranthus palmeri is the first and only broadleaf weed species resistant to this herbicide, and the resistance ...

Quizalofop Resistance in Weedy Rice\u3ci\u3e (Oryza\u3c/i\u3e\u3ci\u3e sativa\u3c/i\u3e L.) is Mainly Conferred by an Ile1781Leu Mutation [PDF]

, 2023
Weedy rice (Oryza sativa L.) is an economically important weed species in rice (Oryza sativa L.) cropping systems. Two weedy rice samples (acc7 and acc8) suspected to be resistant to quizalofop-ethyl (quizalofop) were collected in Arkansas.

Accumulation of target gene mutations confers multiple resistance to ALS, ACCase and EPSPS inhibitors in Lolium species in Chile [PDF]

, 2020
Different Lolium species, common weeds in cereal fields and fruit orchards in Chile, were reported showing isolated resistance to the acetyl CoA carboxylase (ACCase), acetolactate synthase (ALS) and 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS ...
