    When I ran the pesticide division for several tree care companies all applications of imidacloprid were soil injections. Before it was available we were spraying thousands of birches on residential and public properties with Cygon. Now, I shudder at the thought of that.

    Greendoctor, I understand your angst regarding all the regulations. If every applicator had your knowledge, experience and the concern to apply pesticides correctly there would be little need for many of the current regulations. Unfortunately this is not the case.

    In the early years of my career, I remember applying Cygon to shrubs. Those same types of plants are now treated with Imidacloprid. Surely a safer application. However, Imidacloprid does not control mites. I remember the labeling for Imidan too. Prohibited in residential landscapes but allowed in commercial landscapes. That always struck me as odd, because with what I do, I have quite a bit of control over who is on property and where they go.

    Yes we found that many trees & shrubs treated with Imidacloprid developed mite infestations within a month or so. Bayer denied it for years until studies came out showing it was true.

    While it was still allowed, I used soil injections of Dimethoate.

    I wish their was more accountability too.

    Imidacloprid is pretty safe as long as you aren't stocking it at the bar. I certainly consider things we should be letting dry on the lawn, like your average 3 way, more toxic.

    That guy also led to the voluntary ban on basswoods.

    I guess I'll have to stock up.

    On the contrary, bifenthrin used to not be labeled for residential, but now it’s one of the most used insecticides in residential.
    How did that work?

    Right now they would like to eliminate the EPA. I wouldn't anticipate any changes.

    Makes sense, although I don't agree, that they want to ban on turf. All the studies I have seen with colonies don't have neonics because the flowers isn't connected to the plants vascular system, its separate, which is why you want to apply systemically. We do find very high levels of fungicide and adjuvants which makes sense because thats what is being applied during bud break.

    I am not a big fan of liquid merit applied to turf or any insecticide for that matter. It leaves a ton a residue on the leaves for insects/ homeowners to have skin contact. I read somewhere a while ago merit only moves upwards in plants, so a foliar application is basically useless unless watered in before it degrades. Other neo’s move both upward and downward but still a residual issue. Granular only here on any blanket apps whether it’s pre or insecticides and I only spot weed controls. My clients are free to enjoy there lawn and sleep at night without worrying. A step in the right direction, soil injections are another story and a great addition to any ipm program.
