How Does Gibberella Stalk Rot Impact Corn Plants?
Gibberella stalk rot affects various parts of corn plants, significantly impacting their:
Stalks: The most immediate and visible impact is on the stalks, which weaken and become prone to breakage due to pith degradation. This can trigger significant yield losses due to lodging and ear drop.
Ears: The disease can also affect the ears, leading to premature ear drop. In severe cases, the fungus can generate mycotoxins that contaminate the grain, rendering it unfit for consumption.
Roots: The fungus can also invade the roots, causing root rot. This can hinder the plant's ability to absorb water and nutrients, further impacting yield and quality.
