A whole-farm economic analysis in the Big Horn Basin, in which research results were incorporated, showed that by substituting trap crops in the rotation in lieu of nematicides, rate of return could be increased from 3.9 to 5.8% if trap crops were grown as green manure and to 9.5% if trap crops were grazed. In southeastern Wyoming, where different rotations are practiced, whole-farm analysis showed that use of trap crops in lieu of nematicides increased rate of return from 2.5 to as high as 6.3%. Both analyses decreased downside risk. Growing trap crops is less expensive than applying either of the nematicides commonly used and are safer to applicators and others, and are more environmentally friendly. Trap crops can reduce reliance on nematicides and help sustain the historically most profitable crop in the Rocky Mountain region, which generates at least $5 value-added income in processed products for every dollar of farm gate sales.
Project objectives:div style="margin-left:1em;">
1. Determine effectiveness of SBN-resistant trap crops in reducing SBN populations and nematicide use in several alternative sugar beet rotations and with several establishment methods.
2. Determine yield effect, cost and returns of alternative rotations in which trap crops are used in lieu of nematicides.
3. Develop an educational program to demonstrate benefits of trap crops and to encourage adoption of their use by sugar beet producers.
