Data from: Digital morphological data can generate accurate pre-emergence herbicide dose-response curves in <i>Chenopodium album </i>L.
Greenhouse dose-response assays were performed on Chenopodium album L. using pre-emergence treatments of fomesafen and atrazine. Digital collection of data was performed with the Phenospex TraitFinder at 21 days after treatment. This equipment is equipped with two PlantEye scanners that generate 3D models of plants through the laser line triangulation principle, which builds a model of the plants based on the disruptions in the laser line. During the scanning process, the two scanners shine and simultaneously collect reflectance data for the laser, Red, Green, Blue, and Near-Infrared light. Each data point in the resulting 3D model contains not only coordinate information but also spectral data. The Phenospex TraitFinder collects data for 7 spectral parameters and 13 morphological parameters. Spectral data, which often ranges from -1 to 1, is also sorted into bins to detail how many data points fell within a given range. Digitally collected data were compared to manual measurements of fresh biomass and plant height to assess accuracy and determine which Phenospex parameters generate similar dose-response curves and growth reduction 50 estimates. Abbreviations: normalized difference vegetation index, NDVI; green leaf index, GLI; plant senescence reflectance index, PSRI; normalized pigment chlorophyll index, NPCI.
