ALTERNARIA LEAF SPOT

Alternaria leaf spot in melon

 

An infected host will develop a number of lesions on the surface of leaves. Lesions will appear as small circular spots with light brown centers surrounded by dark concentric rings. Spotting is most prevalent on lower, older leaves, but new leaves are susceptible too. Spots that are close together may combine to form one large spot. Heavily spotted leaves will quickly turn yellow, wilt, and fall due to lack of water.

This pathogen is a saprobe, meaning it survives on dead plant material. It can survive off of plant debris both on the surface of soil or below ground. It can also survive in plant seeds. Once the pathogen has infected its host, leaves will develop an array of dark spots.
