Epidemiology of stem rust: II. Relation of quantity of inoculum and growth stage of wheat the rye at infection to yield reduction by stem rust



Epidemiology of stem rust: II. Relation of quantity of inoculum and growth stage of wheat the rye at infection to yield reduction by stem rust



Plant Dis Reporter 43(8): 855-862



In inoculated wheat plots almost complete loss of yield (42 bushels per acre in check versus 0.9 bushels) was obtained when rust severity reached 1% by the early boot stage. Yield reductions were progressively less when this severity was attained at early heading, late heading, milk, and grain development, respectively. While similar relationships between severities attained in relation to host stage were demonstrated in rye plots, yield reductions were not so severe even though there were greater initial levels of infection. Winter wheat retains its green color longer in the spring than does (winter ?) rye. This indicates a difference in speed of host maturation which accounts in large measure for the greater destructiveness of stem rust on wheat, even though initial infection takes place on both hosts at the same time. The test demonstrated that a small amount of inoculum arriving early enough to permit an additional cycle of infection can cause more destruction than 10 times this amount of inoculum arriving at a later developmental stage of the host.
