Diseases & pests on this plant

• fall armywormSpodoptera frugiperdaEU-notifiable quarantine organism

  Young caterpillars skeletonise leaves and make "windowpane" patches; older ones chew ragged holes and burrow into the whorl, tassel and cobs of maize, leaving copious moist sawdust-like frass; the caterpillar has a pale inverted "Y" on the head and four dark spots in a square on the second-to-last segment. Populations build explosively and "march" between crops.
