What this podcast covered
Importance of Timing
The timing of fungicide applications is critical in rice production, particularly during the mid-boot stage, which occurs about 14 days after the green ring. This timing ensures that the fungicide can effectively combat diseases like kernel smut.
Scouting for Sheath Blight
Scouting for sheath blight should begin at the half-inch internode elongation stage. This allows producers to monitor disease presence and make informed decisions about fungicide applications based on the severity of the disease.
Balancing Cost and Prevention
Producers must balance the need for disease prevention with the costs associated with fungicide applications. Understanding when to apply fungicides can help save money while still protecting crop yields.

Questions & answers
Quick answers
When should I apply fungicides for rice?
Fungicides should ideally be applied during the mid-boot stage, around 14 days after the green ring.
What diseases should I be concerned about in rice?
Key diseases include kernel smut and sheath blight, which can significantly impact yield if not managed properly.
How can I determine if sheath blight is present?
Begin scouting for sheath blight at the half-inch internode elongation stage and look for positive stops in the field.
