Abstract
The most effective management program for soybean cyst nematode, Heterodera glycines, is a crop rotation that uses nonhost crops and resistant soybean cultivars. However, little is known about the effects of rotation crops and overwintering on H. glycines biology. These experiments were initiated to determine the effects of seven alternative crops on H. glycines' ability to infect and mature on subsequent soybean crops, and to assess the viability of eggs during the overwintering months. Rotation studies were conducted for 2 years in each of two naturally infested fields, and overwintering tests were conducted in three consecutive growing seasons in one naturally infested field. Rotation crop and fallow treatments did not have a consistent effect on the ability of H. glycines to infect soybean or mature. Soybean yields were often higher following fallow or a nonhost crop than following soybean, although not usually significantly so. Heterodera glycines egg viability did not differ (P < 0.05) between overwintering months at 0-to-10 or 10-to-20-cm soil depths. These results suggest that H. glycines' ability to infect a subsequent soybean crop and develop to maturity is not diminished by nonhost crops or during the winter months.
