There is a renewed interest in nematode pests of corn. Even as producers fine-tune fertility and cultural practices such as planting date and plant density, yields fail to reach the genetic potential of new cultivars in some fields. In many cases, nematodes are a major contributor to stagnant or declining yields. There is an industry push to bring new nematicides to market, so producers who are knowledgeable about nematodes will be positioned to take advantage of new technology and products.
