The answers are the following:
-Rust
- yellow mosaic
- blight
-Stalk rot
—Evidence—
•] Rusts are plant diseases caused by pathogenic fungi of the order Pucciniales.
•] Wheat yellow mosaic (usually called wheat spindle streak mosaic) is caused by a soilborne virus which also is transmitted by the soilborne fungus, Polymyxa graminis.
•] Blight spreads by fungal spores that are carried by insects, wind, water and animals from infected plants, and then deposited on soil. The disease requires moisture to progress, so when dew or rain comes in contact with fungal spores in the soil, they reproduce.
•] Fusarium stalk rot, primarily caused by the fungus Fusarium verticilliodes, is a common disease in the Midwest. This fungus also causes Fusarium ear rot and can infect roots, stalks, and leaf nodes. It is most common in hot, dry years.
