    Giant Hogweed: Identification and Control
    Flessner, Michael; Metzgar, Jordan (Virginia Cooperative Extension, 2020-09-21)
    Giant hogweed is dangerous. Skin contact with its sap in the presence of sunlight can result in severe burning and blistering (Nielsen et al. 2005). For this reason, giant hogweed is both a Virginia and Federal noxious weed (USDA APHIS, VDACS). If you are exposed to the sap, immediately get out of the sun, wash with soap and water, and if a reaction begins to occur, seek immediate medical attention (Hyypio and Cope).

    Implementing Digital Multispectral 3D Scanning Technology for Rapid Assessment of Hemp (Cannabis sativa L.) Weed Competitive Traits
    Singh, Gursewak; Slonecki, Tyler; Wadl, Philip; Flessner, Michael; Sosnoskie, Lynn; Hatterman-Valenti, Harlene; Gage, Karla; Cutulle, Matthew (MDPI, 2024-06-28)
    The economic significance of hemp (Cannabis sativa L.) as a source of grain, fiber, and flower is rising steadily. However, due to the lack of registered herbicides effective in hemp cultivation, growers have limited weed management options. Plant height, biomass, and canopy architecture may affect crop–weed competition. Greenhouse experiments conducted at the joint Clemson University Coastal Research and Education Center and USDA-ARS research facility at Charleston, SC, USA used 27 hemp varieties, grown under controlled temperature and light conditions. Weekly plant scans using a digital multispectral phenotyping system, integrated with machine learning algorithms of the PlantEye F500 instrument, (Phenospex, Heerlen, Netherlands) captured high-resolution 3D models and spectral data of the plants. Manual and scanner-based measurements were validated and analyzed using statistical methods to assess plant growth and morphology. This study included validation tests showing a significant correlation (p < 0.001) between digital and manual measurements (R2 = 0.89 for biomass, R2 = 0.94 for height), indicating high precision. The use of 3D multispectral scanning significantly reduces the time-intensive nature of manual measurements, allowing for a more efficient assessment of morphological traits. These findings suggest that digital phenotyping can enhance integrated weed management strategies and improve hemp crop productivity by facilitating the selection of competitive hemp varieties.

    This guide is a first edition and discusses all the information gained from the limited work with hemp in Virginia thus far. Knowledge will continue to evolve in the coming years as more is learned about pest management and best practices for hemp growth and production. Management options are extremely limited for hemp currently.
