WWW.POTATOGROWER.COM 33 "A potato crop can face a variety of issues each year that threaten its health and yield potential, including diseases brought on by adverse weather conditions," says Rainbolt. "Growers should control what they can and protect against what they cannot. Growers can help manage these issues by controlling yield-robbing diseases through fungicides." MANAGING RESISTANCE While using fungicides to control early blight in a potato crop, growers should be mindful of the products they choose and the management techniques they implement to fight fungicide resistance. "One practice we recommend growers follow to fight resistance is beginning their spray programs with the most effective fungicides," says Rainbolt. "Growers should use tank mixes of protectants like chlorothalonil or mancozeb-based fungicides with Endura fungicide." Endura has a single mode of action that allows for tank-mixing flexibility to further manage fungicide resistance development. Other practices Rainbolt recommends growers follow to manage fungicide resistance include limiting the number of sprays with the same mode of actions and rotating different modes of action in spray programs. DETERMINING THE BEST PLAN Use of fungicides to control early blight should exist within a comprehensive integrated disease management plan. Practices such as rotation with non-host crops, avoiding irrigation in cool, cloudy weather, and the removal of infected plant debris all help reduce the risk of early blight inflicting a grower's potato crop. "Growers can work with their local chemical representative to determine how fungicides can work within their integrated disease control plan," says Rainbolt. "Our reps recommend Endura fungicide to be included in a grower's disease management plan so they can get ahead of early blight while preserving their crop's yield."
