Natural feeding of S. litura larvae.
Artificial regular damage of leaves (upper portion showed, a = healthy leaf, b = 25% damage, c = 50% damage and lower portion is the reconstruction of damage in BioLeaf application for damage quantification)
Artificial irregular damage (Type 1, and II), a = healthy leaves, b = irregular damage, c = hole and border reconstruction in BioLeaf application for damage quantification.
Infected leaf of citrus due to citrus canker disease (a = natural damage, b = quantification of damage by BioLeaf application).
Reference object to convert the area from pixel to cm2.
Relationship of BioLeaf analysis with ImageJ and CI-202 LAM for quantification regular damage of soybean leaves (A), sunflower leaves (B), soybean leaves (C), sunflower leaves (D), and for quantification of natural damage of soybean and sunflower leaves due to S. litura feeding (E), and quantification of infected leaves of citrus due to citrus canker disease (F).
