Would you recommend Merit 75 WSP for Emerald Ash Borer treatment or another product?


We would recommend using Domnion 2L. It is labeled for use on trees for emerald ash borers as a preventative and a curative. This only needs to be done once a year. The mixing ratio is 0.1 to 0.2 fl oz per inch of the trunk diameter. This needs to be mixed in at least 5 gallons of water and poured around the roots of the tree.
