We concluded that IMA-jet injection is an acceptable preventative treatment for management of SLF attacking ornamental trees in Pennsylvania. Download the Research Handout

"I’ve been injecting a 70“ ash tree on the campus of Miami University since 2014. It has typically taken three long mornings to coax the needed volume of TREE-äge® into this tree. Using R10 for the first time, the entire treatment for 2020 was completed in 2.5 hours, in mid-August! R10 is revolutionary for my business - reading about R10 is one thing, an experience such as this quite another. I’ve instantly become a convert.”
