Abstract
A method of controlling cyst nematode population in soybeans by providing a blended composition of soybean varieties. At least one of the soybean varieties in the blend has resistance to a given race spectrum, while another of the soybean varieties in the blend may have resistance to a differing race spectrum or be a susceptible variety. The blend may include 10 to 90% of the first variety and 90 to 10% of the second variety. The blend may consist of three or more soybean varieties.
Claims6
A method of controlling cyst nematode population in soybeans, comprising the steps of:
- providing a quantity of a first cyst nematode race resistant soybean variety having resistance to a first race spectrum;
- providing a quantity of a second soybean variety selected from the group consisting of a cyst nematode race resistant soybean variety having resistance to a second race spectrum and a cyst nematode susceptible soybean variety;
- providing a quantity of a third soybean variety selected from the group consisting of a cyst nematode race resistant soybean variety having resistance to a third race spectrum and a cyst nematode susceptible soybean variety;
- blending the first, second and third soybean varieties to achieve a first blended composition;
- planting said first blended composition to yield a soybean crop;
- and
- rotating the growing of said first blended composition of resistant soybean varieties with the growing of a second blended composition of resistant and susceptible soybean varieties over at least two growing seasons which results in controlling cyst nematode population in said soybeans.
