37. Prescription Programs- Long Season Cultivars Be aware of tropical storms later in the season that may delay harvest. Delay start of fungicide programs and stretch interval between fungicide applications, especially in drier weather.

38. Prescription Programs in General USE REDUCED FUNGICIDE INPUTS ONLY IN LOW RISK FIELDS! Prescription programs are now endorsed by Syngenta MOST fungicide programs can be modified to low, medium, and high risk fields
