Evidence of phytophagy

Submitted by zalam on Sat, 10/05/2019 - 15:01

Phytophagy can be seen almost anywhere around us. I found mine in the Durfee Conservatory on the UMass Amherst campus. The subject was a plant with long green leaves. Every single leaf was pristine clean with no other patches, holes etc. except one leaf. This specific leaf had three patches in a trianglular orientation. The patches did not have specific shape - they were irregular. They did not occupy space on the entire leaf, but were big enough to be visible They were located about two-thirds from the bottom and on the underside of the plant. This was an evidence of phytophagy because it usually means that it had been attacked by a fungus or bacteria causing the discoloration. The brown patches were slightly lighter around the borders and got darker as they got closer to the center of the each patch.
