Fusarium stalk rot No discoloration occurs on the outside of the stalk, but the nodes may appear white due to growth of the fungus on the outside of the stalk. Compared with the 0% control, biochar addition at the low concentration of 0.5% enhanced corn growth. But in the case of the Fusarium stalk rot, you will not find them. Eventually, the disease may cause a pink to salmon discoloration of the inside of stalks. This can be used as a differentiation from the other rots. Fusarium moniliforme Symptoms: The leaves turn from a healthy green color to a dull green and the lower stalk becomes yellowed. Premature plant death may occur and lodging due to disintegration of the internal stalk pith tissue; when squeezed between the thumb and index finger at the lower nodes, the stalk often collapses. In many of the stalk rot diseases, black specks might be observed. 2, below) may be seen in the pith of infected plants when the stalks are split open. Fusarium stalk rot was observed in the plant age group of 55 to 65 days which coincides with tasselling and silking and immediately followed grain formation stage. Fusarium stalk rot, probably because the fungus can survive in the soil for long periods during inclement con-ditions or in the absence of a host. In general, the application of biochar controlled the disease. Fusarium verticillioides also causes stalk rot in sorghum and seedling and ear rot diseases in corn. The pathogen, Fusarium verticillioides, can sometimes be visible as white fungal growth on the outside of stalks at the nodes. Similarly, for fusarium stalk rot, pathogens survive on sorghum residue once the crop has been harvested but researchers would like to know how long it can survive under various conditions. A pink discoloration (Fig. Fusarium stalk rot was observed in the plant age group of 55 to 65 days which coincides with tasselling and silking and immediately followed grain formation stage. In our previous studies, we identified several pathogens associated with stalk rot disease incidence and Fusarium was major threat in all the study regions. Fusarium Stalk Rot About the Disease: The disease is caused by Fusarium species and is characterized by a pink colored discoloration of the stalk. Often, hybrids resistant to other fungal stalk Fusarium stalk rot is especially common during damp conditions, but may occur anywhere, including in irrigated fields this year. The efficacy of biochar prepared from rice husk and bamboo at 500°C against stalk rot of corn caused by Fusarium graminearum was tested at biochar doses of 0, 0.5, 1, 2 and 3% (w/w).
