R O OT H E A LT H I N P OTATO E S ADVERTORIAL Why It Pays to Focus on Root Health A plant's root system is not only responsible for water and nutrient uptake, it is especially critical for crops like potatoes, where healthy roots support tuber development which determine both production yield and quality. "Good root health is vital when plants are in good condition and even more important when plants are facing stress from weather, pests or disease," said Dr. Mike Thornton, Extension Plant Physiologist and Professor at the University of Idaho. Soil Pests At least 18 species of nematodes are known to cause yield and quality issues in the U.S. Yield losses due to nematode infestation vary depending on potato cultivar and level of infestation, but research has shown that yield loss can range from 19 to 90 percent, according to a USDA APHIS publication. 1 "Growers need to be vigilant and prepared for nematodes every season," says Kelly Luff, Senior Technical Representative for Bayer. Soil Diseases Several of the pathogens that cause the most damage in U.S. potato production originate from soilborne inoculum such as Rhizoctonia, leading to diseases that can affect both crop development and tuber quality. 2 Comprehensive Approach A comprehensive approach to root health includes both management practices and product solutions. Bayer has introduced a full range of solutions that allows potato growers to get their crops off to a strong start leading to successful harvests. The comprehensive program also provides sustainability and crop management bene ts, requiring fewer applications and lower dose rates. Research has shown that nematode yield loss can range from 19 to 90 percent. A strong root system is the foundation of potato plant health and tuber development, leading to higher quality and higher yields for potato growers. 1 USDA Animal and Plant Health Inspection Service, Golden Nematode Program Update, Daniel Kepich. 2 Management of soilborne diseases of potato.

Start with the Seed Potato growers can build the best foundation for their crops by treating seed pieces with Emesto ® Silver. Emesto Silver provides good activity on seed- borne Rhizoctonia and Fusarium (including resistant strains) and Silver scurf. Protect Against Soilborne Diseases Serenade ® ASO fungicide can be foliar or soil-applied to provide disease control against foliar and rhizospheric bacterial and fungal diseases. Serenade ASO also plays a key role as a root health activator and can change the interaction between the soil and the plant, leading to healthier roots and improved, vigorous tubers. In-season Nematode Management An innovative combination from Bayer, the V+M Solution provides a cost-effective, convenient solution for managing a broad spectrum of insect and nematode species and several diseases. The V+M Solution combines the wide-spectrum nematicidal activity of Velum ® Prime with the sustained in-season nematode and insect protection of Movento. ® Dr. Saad Hafez, University of Idaho. Signifi cant Protection Against Nematodes and Diseases Untreated Velum ® Prime + Serenade ® ASO Summary Combining effective management practices from seed treatment through harvest with a compre- hensive package of fungicides, nematicides and insecticides from Bayer can give potato growers con dence in their crops' root systems producing healthy plants and generating higher yields.
