One important approach to nematode control is the generation of crops with internal nematode resistance. While some crops have genetic sources of resistance, many lack identified resistant germplasm. Furthermore, selection for parasites that can overcome genetic resistance in crops like soy and potato has rendered some traits ineffective. Providing nematode resistance as a biotechnology trait offers the possibility of providing highly-specific season-long protection from nematode damage without requiring chemical treatment. This biotech approach is particularly attractive in high-acreage row crops such as soybeans, corn, and cotton where costs of in furrow nematicide treatment are often prohibitive. The adoption of biotechnology traits in these markets is already very high. In the United States, greater than 90 percent of soybeans, 85 percent of cotton, and 50 percent of corn acreage contain one or more biotechnology traits. Divergence is developing safe and effective biotechnology traits for nematode control based around the discovery of nematicidal metabolites, proteins, and nucleic acids.
