Suppression of Disease with Agronomic Practices in Recently Released Spring Wheat and Winter Wheat Cultivars
Suppression of Disease with Agronomic Practices in Recently Released Spring Wheat and Winter Wheat Cultivars, 2007 This study was designed to examine whether a synergy exists between chloride (Cl-) nutrition and fungicide application in winter and spring wheat. The study was conducted at two sites in North Dakota in 2007. Heading applications of Cl- were not effective in reducing scab in winter wheat. Soil application of Cl- as calcium chloride (CaCl2) reduced leaf diseases at one site.

Objectives
- Identify recently released varieties of spring wheat and winter wheat in which diseases could be suppressed by soil or foliar applied Cl (root rot, tan spot, leaf rust, stem rust, and head scab) as well as when more expensive fungicides (Tilt and Quadris) are applied.
- Determine if late season foliar Cl applications could suppress diseases as well as late season fungicide applications so that farmer’s have a option to wait until diseases become obvious or conditions for infection are evident and the input costs are lower than fungicide treatments.
