Disease Control • Rotating crops in a particular eld can prevent diseases from overwintering, according to University of Idaho Extension. • Fungicides can help eradicate both diseases and should be applied preventively or at the rst sign of Early blight symptoms. • Vigilant monitoring and management of Early blight and White mold are needed as potato crops get closer to maturity and harvest. Disease Threats • Early blight thrives in wet conditions and can lead to smaller potatoes, lower dry matter content and yield loss. • White mold also thrives in moist conditions and excessive irrigation. White mold causes a rapidly spreading, cottony-white growth and might cause plant death. It also overwinters, potentially resulting in ongoing losses. Growing high-quality potatoes requires ultimate balance and precision. Too much nitrogen late in the growing season reduces crop yields, but not enough early on suppresses tuber growth. The same irrigation practices that promote healthy canopy growth to support tuber bulking – and increase yield – cause moist conditions that can lead to serious fungal disease pressures in potatoes. As a breakthrough systemic fungicide, Luna ® controls White mold, Early blight and other problematic diseases so potatoes stay healthy from their rst sprout to their place on a shelf. A trial conducted by Miller Research for the Idaho Potato Commission showed Luna Tranquility ® helps reduce Early blight severity by 97% and helped improve yield by 10%, leading to an additional +$543 per cwt./A in pro ts. 1 UNTREATED LUNA TRANQUILITY ® 11 oz.
