Abstract

A comparison was made of various techniques for isolating Pyrenochaeta terrestris (Hansen) Gorenz et al. from growing onion roots. Water agar was as suitable as potato dextrose agar (0.5% dextrose) and is recommended to avoid contamination. Texas L 303, Iowa Yellow Globe 51, and Trapp's Downing Yellow Globe used as trap crops were equally efficient. Maximum infection of the early planting occurred earlier than a later planting.
