The Ontario Potato Board reports that late blight spores were detected in their two spore traps in the Shelburne and Alliston areas on July 7. Late blight symptoms have not been detected, but it means that spores were present in the area.
Growers across Ontario should be scouting their crops frequently. Late blight (US-23 genotype) was detected in south central Michigan on July 5.
See Late blight update – July 10 for more information on managing late blight in tomatoes.
Thanks to Dr. Eugenia Banks and the Ontario Potato Board for the spore trapping results. Their project is supported by Growing Forward 2.
