Biotic Stress: Herbivory, Infection, Allelopathy

A leaf of the broad-leaved dock (Rumex obtusifolius) that has been perforated by leaf beetles (Chrysomelidae) and their larvae. Further clutches of eggs are on the leaf lamina. In the right margin of the picture, two spots with red edges, which show the accumulation of anthocyanln, Indicate a hypersensitive reaction. This Is probably due to an additional pathogen attack.
