Fusarium stalk rot — Maize
Fusarium verticillioides
Symptoms
Plants wilt prematurely, although the dry stalk may remain standing. Small, dark-brown lesions develop on the lower internodes. When the stalk is split open, the phloem and internal tissues show conspicuous brown discoloration. The pith becomes shredded in advanced stages. Infected plants may lodge, particularly when the stalk becomes weak.
Recommendations
Carboxin 37.5% + Thiram 37.5%
(WS)
seed treatment with the recommended dose is the best solution. Applying recommended potassium and reducing moisture stress during flowering time may reduce the severity of incidence. If disease incidence is noticed, follow proper crop rotation to avoid multiplication of the pathogen.
