Abstract: Highlights•In-field classification of the asymptomatic biotrophic phase of potato late blight.•Proximal hyperspectral images collected in multiple days with 20 potato genotypes.•A new 3D convolutional deep learning architecture PLB-2D-3D-A is proposed.•Important wavelengths are determined for early PLB disease recognition in fields.
