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.

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. CaCl2 seemed to increase yield at the spring wheat site. These studies will be repeated in 2008 to further investigate if CaCl2 consistently demonstrates these effects. Future work will examine both Cl- and copper (Cu) and the interaction with foliar and heading-applied fungicide on winter and spring wheat. ND-13
