The statement that "it spreads rapidly during periods of high temperature" is not true about stripe smut. Stripe smut, caused by the fungus Ustilago avenae, typically thrives under cooler conditions rather than during high temperatures. This disease is more commonly observed in spring and fall when temperatures are moderate, which is when conditions are more favorable for its development and spread.

Understanding the characteristics of stripe smut is crucial for effective management. It is indeed most noticeable in the spring and fall and can cause visible symptoms like the splitting of leaves to reveal the characteristic black spore masses.

Proper agronomic practices, such as appropriate fertilization and ensuring that plants are not over-watered but receive adequate deep watering, can help reduce the severity of stripe smut infection on plants. Failing to provide the right conditions can further exacerbate the spread and impact of this disease on crops.
