Abstract

Onion (Allium cepa) root infection by Sclerotium cepivorum was examined in two glasshouse bioassays In the first bioassay the effect of sclerotial depth was examined Sclerotia placed at 1 10 and 20 cm depths in soil filled planter bags germinated and infected onion roots at 5 7 and 13 weeks after planting respectively The second bioassay determined that the severity of infection varied when sclerotia were placed at the stem base along the length of a root and at the root tip After 22 weeks a greater (P<005) number of stem base infections led to total plant collapse compared to infections occurring along the length of the root or at the root tip
