Stenocarpella maydis (Berk.) Sutton (syns. Diplodia maydis (Berk.) Sacc. and D. zeae (Schwein.) Lév.) is a plant pathogenic fungus and causal organism of diplodia ear and stalk rot. Corn (Zea mays) and canes (Arundinaria sp.) are the only known hosts to date.[1] No teleomorph of the fungus is known.[2]
Stenocarpella maydis can significantly reduce yield or grain quality (see – Symptoms and Signs) as there is a decrease on kernel size, and lower test weight. If infection occurs early, some ears may not produce harvestable grain or seed vigor can be compromised.[2][3] Delayed harvest and wet weather before harvest can allow fungal growth to continue, further reducing grain marketability.[4] Further, some animals may reject contaminated corn-based feed. Stenocarpella rot has the potential to affect distillers dried grains with solubles (DDGS) composition, but not ethanol yield on an equivalent weight basis.[5] Although not common, when the conditions are conducive, this organism can produce mycotoxins (see – Importance), toxic compounds to mammals.
