Abstract Combine modifications for harvest weed seed control, like the Redekop Seed Control Unit (SCU) and integrated Harrington Destructor (iHSD), have been successfully used to kill problematic seeds in small grain production Australia. These impact mills could a fit US soybean [Glycine max (L.) Merr.] production. Testing rate of species is important confirming efficacy mills. Additionally, may be affected by changes crop yield residue moisture as they can an on chaff flow moisture,...
Abstract Seed impact mills, like the Redekop Control Unit (SCU) and integrated Harrington Destructor (iHSD), have potential to fit within U.S. wheat ( Triticum aestivum L.) production system, but they may be affected by changes in crop yield harvest residues moisture as can an on chaff flow rate moisture, respectively. This research aimed determine seed kill of problematic weed species how varying rates affect horsepower draw SCU iHSD. Four different were tested at 0.75, 1.5, 2.25, 3.0 kg...
Abstract Poa annua L. (annual bluegrass) is a common weed in turfgrass and has been reported resistant to 12 different herbicide sites of action, with various combinations multiple‐herbicide resistance having identified. To quantify the extent herbicide‐resistant P. , ResistPoa Project (resistpoa.org) surveyed 1349 populations for nine action one plant growth retardant. Herein, we report results from sequencing known target site mutations found 5‐enolpyruvylshikimate‐3 phosphate synthase (...
Abstract Dithiopyr and dinitroanilines are preemergence-applied, mitotic-inhibiting herbicides used to control goosegrass [ Eleusine indica (L.) Gaertn.] in turfgrass. A suspected resistant E. population was collected from a golf course putting green evaluated for possible resistance dithiopyr prodiamine. After dose–response evaluation, the α-tubulin gene sequenced known target-site mutations that have been reported confer herbicides. mutation discovered resulted an amino acid substitution...
Abstract Advanced sequencing techniques have improved the ability to identify and understand target‐site resistance in herbicide‐resistant species. Despite innovations sequencing, polyploid species can still face issues that are typically not seen diploid species, often because of presence conflicting subgenomes. Further confounding difficulties polyploidy is α‐tubulin gene, which has subgenomic duplication gene family copies. Poa annua L., an allotetraploid, a persistent weed turfgrass...
Abstract The goal of weed science extension efforts are to encourage and accelerate adoption diverse, effective, economical management tactics. To be most successful efficient, personnel need know how growers prefer receive information, the format in which information is delivered, areas that future research should focus on. this end, surveys were distributed at crop forage meetings Virginia. results from 249 responses indicate both producers have similar preferences. Agribusiness (e.g.,...
Abstract Mitotic-inhibiting herbicides, like prodiamine and dithiopyr, are used to control annual bluegrass ( Poa annua L.) preemergence in managed turfgrass; however, resistance mitotic-inhibiting herbicides has evolved due repeated applications of herbicide from a single mechanism action. Three suspected resistant populations (R1, R2, R3) were collected Alabama Florida screened for prodiamine. Part the α-tubulin gene was sequenced known target-site mutations. Target-site mutations reported...
