A method for estimating spore numbers of Erysiphe cruciferarum using infra-red reflectance analysis

A method for estimating spore numbers of Erysiphe cruciferarum using infra-red reflectance analysis

Cruciferae Newsletter (8): 40-42

Eight swede cultivars were grown in a glasshouse and inoculated with E. cruciferarum at the 2-3 leaf stage. After 33 days the numbers of spores present were estimated using infrared reflectance analysis and haemocytometer counts. The correlation coefficient between the two methods was very high.
