If using Propiconazole 14.3 Fungicide with the Chemjet Injector, how many injections 20ml (50/50 mix) does a 23" diameter Elm Tree need to prevent Dutch Elm disease.

I have read all the instructions watched the video can't seem to find out how many injectors/injections for my 23" diameter elm tree. I have read thru everything twice. Please help me and point me in the right direction to find the calculation.


We do not currently carry any injectable products for trees due to our suppliers not carrying these specialized products and injection applications should be performed by local professionals. We apologize we could not be more helpful!
