Target Spot (Rhizoctonia Leaf Spot) is being seen in several fields (click here for photo). The wet conditions and moderate temperatures in the latter part of June and early July were ideal for development of this soil-borne fungus. In most fields at this time it appears that the lesions are no longer water soaked and are not active. Further information about the disease and control can be found in OMAF’s tobacco publication.
