Differentiating stress to wheat fields induced by Diuraphis noxia from other stress causing factors

► Diuraphis noxia induced stress and cause economic loss to wheat production. ► Multispectral image data can be used to detect stress in wheat fields. ► Stress in wheat fields may be a mixture of several stress causing factors. ► Spatial pattern metrics from multispectral imagery can be used to quantify stress. ► A discriminant function analysis can be used to differentiate stress induced by D. noxia from other stress causing factors.
