Evaluation Of Weed Control Efficacy And Crop Tolerance To Florpyrauxifen-Benzyl Coated Onto Urea, Bodie Lyn Cotter
Evaluation Of Weed Control Efficacy And Crop Tolerance To Florpyrauxifen-Benzyl Coated Onto Urea, Bodie Lyn Cotter
Graduate Theses and Dissertations
Frequent off-target movement occurrences to soybean [Glycine max (L.) Merr.], rice (Oryza sativa L.) injury, and a lack of barnyardgrass [Echinochloa crus-galli (L.) P. Beauv.] control followed the commercial launch of florpyrauxifen-benzyl in 2018. Florpyrauxifen-benzyl is a synthetic auxin, Herbicide Resistance Action Committee (HRAC)/Weed Science Society of America (WSSA) Group 4 herbicide used for postemergence weed control in rice and labeled for application at 30 g ae ha-1. Previous research documented that soybean was susceptible to injury following spray applications of florpyrauxifen-benzyl at less-than-labeled rates, and certain varieties of rice are less tolerant to spray-applied florpyrauxifen-benzyl at 30 g ae …
Development And Use Of A Detached Leaf Assay To Assess Soybean Cultivar Resistance To Target Spot, Caused By Corynespora Cassiicola, Rachael Wolf
Graduate Theses and Dissertations
Target spot, caused by the fungus Corynespora cassiicola, was once considered a minor foliar disease of soybean in the US. However, a severe outbreak of target spot occurred in the southeastern U.S in 2016. Due to the lack of information on resistance in soybean cultivars, and the challenges in screening cultivars in the field, a detached leaf assay was developed to evaluate resistance. The objectives of the effort were to 1) develop a greenhouse inoculation method of soybean with C. cassiicola 2) use that method to compare reactions of soybean germplasm lines to target spot 3) collect and characterize isolates …
An Investigation Of Seed Hardness And Seed Coat Color Values In Natto Soybean, Joshua Winter
An Investigation Of Seed Hardness And Seed Coat Color Values In Natto Soybean, Joshua Winter
Graduate Theses and Dissertations
Natto is a specialty fermented soyfood made from small-seeded (seeds-1) soybean varieties. Seed hardness and seed coat color are important seed traits that determine the texture and appearance of natto and are thus valuable to breeders. Prior research has identified quantitative trait loci (QTL, hereafter) for seed hardness, but its nature as a quantitative trait heavily influenced by the environment means that it is still poorly understood. Prior research has identified the primary genetic components of seed coat color using simple visual inspection, but few studies have investigated the usefulness of more quantitative measurements, such as the color space coordinates …
