Hello from the Atlas Mountains in Morocco, I hope somebody on the list can help me find the reason our two-year pear trees produce a honey-like sticky substance.
I was told it is pear psyllia, but I do not see any insects on the trees. Somebody else suspected gummosis. I am familiar with gummosis on cherry trees, but the sap we see on the pear trees is less viscous, and forms only a thin layer that drips on leaves. Thanks for your help, Mo
