 Soybean cyst nematode is the number one yield-reducing pathogen of soybean in the United States, and it has been that way for the last 50 years. We try and manage that pest primarily through planting resistant varieties. Unfortunately, like all things in agriculture, if you use a single tool for a long period of time, the pest adapts to that. So that's why we're looking at bringing a new type of technology, BT, to soybean for the management of soybean cyst nematode.
