| Abstract: | Brassica napus L. production has become more predominant in the United States. Increased yield in rotational systems and the increased market for this crop have created a potential for B. napus expansion into regions where it is not currently utilized. This has created a gap of knowledge that is necessary for proper management and implementation of this crop. The objectives of this project were to determine potential controls for volunteer weed issues found in B. napus cropping systems, as well as control of volunteer/weed B. napus in wheat cropping systems that have been incorporated in the southern latitudes of the Great Plains. A secondary objective was the refinement and potential implementation of a new precision farming tool Terrestrial Laser Scanning (TLS). Findings suggest that application of Potassium salt of Glyphosate had significant (P[less or equal to]0.05) impact on weed control in B. napus cropping systems and chemicals such as Flufenacet and Bromoxynil were found to be best in control of volunteer/weed B. napus in a Triticum aestivum L. system with high significance (P[less or equal to]0.05) when compared to untreated control trials. TLS was found to be effective in regards to discriminating monocots in a B. napus cropping system or discrimination of B. napus in a Triticum aestivum L. cropping system using a combination of intensity value and structural characteristics.
