So I took a sales and management job this spring and it's been a serious struggle identifying any non common diseases and pest issues much less treatments and treatment windows for these diseases. The previous arborist never created a treatment cheat sheet either. So my question is does anyone know of specific literature that I should buy that can help me not only identify but create a treatment plan for most diseases in my area? I have one other guy in our other branch in another state i can use for help but I think he's pretty sick of me. @JD3000 I'm hoping you've got something!
