Abstract
The sugarbeet cyst nematode (SBCN) is a serious pest of sugarbeet. Use of a nematode-resistant, trap-crop oil radish as a second crop foUowing harvest of dry bean and com was studied for its potential to reduce soil populations of SBCN and, therefore, reduce nematicide use. Radish (Raphanus sativus L.) was groWn on four SBCN-iofested fields, two foUowing corn harvested as silage and two foUowing dry bean barvest, in comparison to an unseeded control treatment (main plots). Subplots consisting of aldicarb at thr~ rates were randomized witbin main plots at sugarbeet planting tbe following year. The design was a randomized complete block with six replicates. Moisture was not adequate for radish growth at one site. At the other sites, radish growth varied from 416 to, 1453 kg ha1 • Soil population of SBCN declined 57% (P O.05) at three other sites. Including SBCN-resistant radish in the dry bean-sugarbeet and coro-sugarbeet rotations increased (P o.05). At the other site where silage com was grown, aldicarb but not radish, increased sugarbeet yield (P O.OS). No disease or insect pest was detected on radish, nor was any disease or insect pest of sugarbeet increased by growing S8CN-resistant radish as a second crop. This study showed that the potential of substituting SBCN-resistaot oil radish for nematicide following dry bean and corn in southeast Wyoming is limited. Substituting a small grain for corn or dry bean would allow more growing degree days (GDDs) for radish growth and SBCN activity.
