Small round yellow, brown or black spots on leaves; concentric ringed pattern; holes in leaves where lesion has dropped out
Fungi
Treat seeds with hot water prior to planting; prevent disease by keeping plants well watered; if disease emerges remove and destroy plant; remove all plant debris from soil as fungi can survive on pieces of plant
Singular, or closely grouped circular to irregularly shaped holes in foliage; heavy feeding by young larvae leads to skeletonized leaves; shallow, dry wounds on fruit; egg clusters of 50-150 eggs may be present on the leaves; egg clusters are covered in a whitish scale which gives the cluster a cottony or fuzzy appearance; young larvae are pale green to yellow in color while older larvae are generally darker green with a dark and light line running along the side of their body and a pink or yellow underside.
Insect
The armyworm, Pseudaletia unipuncta, is sometimes called "true armyworm" to distinguish it from other species that include "armyworm" in the common name. In Florida, Fall armyworm, Spodoptera frugiperda is often called armyworm, and occurs frequently; in contrast, Pseudaletia unipuncta is not found frequently in Florida.
This insect can go through 3–5 generations a year.
Organic methods of controlling armyworms include biological control by natural enemies which parasitize the larvae and the application of Bacillus thuringiensis; there are chemicals available for commercial control but many that are available for the home garden do not provide adequate control of the larvae.
Spread by seed; poor air circulation favors spread
