518 comment: Anthocyanin is the red to purple pigments composed of soluble glycosides of anthocyanidins, present in leaves and floral tissue. Usually the pigment is produced under stress conditions. Amounts of anthocyanin produced depend on stored sugar and sunlight. The more stored sugar in the leaf and brighter the autumn days, the more intense red. Anthocyanin production also increases as phosphates move out of the leaves; the lack of phosphates in young leaves can also lead to the production of anthocyanin.

Young lesions are pale to grayish green, later turning yellow to grey (dead) with time. In very susceptible varieties, lesions may extend to the entire leaf length into the leaf sheath. Young leaves should not be inoculated for assay. Old or leaves with symptoms of nutrient deficiency or other diseases should also be avoided for inoculation.

2094 comment: The worms appear suddenly in masses and move like an army from field to field so that seedbeds or the direct seeded fields look as if grazed by cattles. Generally, a transplanted crop is not severely affected. Damage by armyworms is most serious during periods of stem elongation and grain formation. Larvae defoliate plants, typically by chewing angular pieces off leaves. They may also feed on the panicle near the developing kernels causing these kernels to dry before filling. This feeding causes all or parts of the panicle to turn white. If the entire panicle is white, the damage may also be due to stem rot or feeding by rats. The seriousness of armyworm injury depends on the maturity of the plant and the amount of tissue consumed. Significant yield reduction can occur if defoliation is greater than 25% at 2 to 3 weeks before heading. They migrate from field to field and extensive losses are often caused within a week. Their migration is facilitated by the absence of standing water in the field.
