These microscopic roundworms feed on plant roots and transmit diseases, causing a variety of symptoms. But solutions exist that can help to reduce crop damage, treat infestations in the current season and prevent infestations from remaining in the field for the next season. "To protect potatoes from nematodes throughout the season, implementing an integrated management system is critical," says Steve Olson, senior product manager at Bayer Crop Science. A Pest of MAny VArieties Root-knot nematodes are one of the most widely found varieties of nematodes and affect numerous crops, including potatoes. Their larvae invade roots or tubers and establish feeding sites, causing reduced plant vigor and blemishes on tubers. As their name suggests, root-knot nematodes can also cause hard, swollen knots to form on plant roots. Another type of nematode commonly found throughout potato-growing regions is the golden nematode, which feeds on plant roots and develops into swollen cysts at the feeding site. These nematodes get their name from the golden-yellow stage they pass through before becoming the cyst. treAting neMAtodes to ProteCt QuAlity And yield One cultural practice to aid in nematode control is early harvesting of potato varieties that mature quickly. The longer tubers remain in the field, the more likely it is that nematodes will have an effect on the crop. Ensuring fields have the proper balance of nutrients and proper fertilization can also help improve plant strength, resulting in reduced nematode impact. Crop rotation can also provide a solution that helps reduce
