title: Influence of Metyrapone on Development of Heterodera glycines.
abstract: Metyrapone, an inhibitor of steroid synthesis, affected the survival and rate of development of Heterodera glycines. Metyrapone in aqueous tartaric acid solvent influenced sex ratios. The effect on sex ratios was mediated through the host, whereas the effect on survival was apparently effected directly. Tartaric acid increased larval penetration of soybean roots.
