Comment:
We observed spots on the leaves and early leaf drop from the LTER and GLBRC poplar trees so we sent a sample to the MSU diagnostic lab.
The attached sheets shows the results.
We received the results from the MSU diagnostic lab concerning the GLBRC and LTER leaf samples. Results: Marssonina leaf spot in the LTER and GLBRC poplar trees.
Marssonina Leaf Spot (Marssoina populi) Management: At this time no changes will take place with the management of the trees at either site after the diagnosis of septoria and marssonina.
Attached you will see the reports sent by the diagnostic lab.
