Anthracnose stalk rot, instigated by the fungus Colletotrichum graminicola, is a widespread and damaging corn disease. It flourishes in environments with high humidity and temperature, the perfect breeding ground for the fungus.
Impacting the stalk's strength and integrity, Anthracnose stalk rot-infected plants suffer significant yield losses due to premature plant death, poor grain fill, and an increased likelihood of lodging, further complicating harvest.
Moreover, the disease can also indirectly influence corn quality. Infected plants are more susceptible to secondary infections by other pathogens, which can further decrease yield and grain quality.
