摘要: Abstract The characteristically clustered occurrence and low level of mobility Heterodera schachtii Rhizoctonia solani in the soil induction stress symptoms sugar beet canopy make them ideal targets for site-specific arrangements with precision agriculture tools. A field site infested H. R. was investigated 2009 near-range aerial hyperspectral sensors during growing season. At 31 sample points ground truth data incidence severity two organisms were collected geo-referenced. Spectral vegetation indices computed from reflectance measurements obtained flight campaigns (AISA, 17th June; HyMap, 28th August) spectroradiometers significantly correlated (P
