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. Key Words: sex ratio, cyst nematodes, soybean.
