acephate as a bark spray: Who has applied this way, with what product?

It's recommended by the labels to apply acephate as a soil drench or a trunk injection, but can it be used as a bark spray? I've heard one arborist talk about it, but don't know the specifics. The label says foliar application is okay....so it doesn't seem like a stretch.
 
Since I wrote this post, I heard from Rainbow Ecoscience that acephate is not effective as a bark spray. I'll be using it as a soil drench this year, hopefully with good results.
 
It does have a REALLY strong smell. I have it in 3 ziplock bags and a plastic "ammo" case and it still stinks up the pesticide cabinet.
 
That's why I like Acecaps. They come sealed up so they don't smell. Drill and insert, so there's no smell on the site, no drift and no movement in soil.
I just can't justify injuring trees for a few weeks of protection, especially the 1/2" holes. I'd rather do a trunk spray or soil injection with a different chemical like dinotefuran. Or canopy spray with something mellow for some knock down. I generally only trunk inject emamectin benzoate for some tough invasives since it's supposed to last 2-3 years. Idk depends on the job, pest, tree species etc but I haven't found myself keeping it around for much.

Have you had good control of pests with emamectin benzoate? I have the type by Rainbow, called Mectinite for micro injection, but I haven't used it yet.

Have you used dinotefuran to control leaf feeding caterpillars? Thank you

Nope, I don't think it's too effective for lepidoptera. We don't really have much of an issue with lepidoptera pests where I live. Most of the outbreaks occur going into winter when target hosts are senescing. In the rare case it's bad I usually knock down with something like BT or spinosad, or introduce parasitic wasps and plant beneficial flowering plants . I would consider using acephate if it made sence, probably as soil drench.

Try carrying around a single-bagged fetid sloth shoulder for a couple hours...

Em benzoate is my strong preference for treating Browntail moth for reasons explained above- less wounding and much more pleasant to work with

Anyone who hasn't heard of Browntail moth should look it up - it's a real weird pest- nightmare for arborist here in Maine and basically nowhere else iirc

Sean, is there a way to use emimectin benzoate other than injections? Mectinite is only for injections as far as I know. I've been noticing a lot of BTM nests in Topsham and Durham this winter, by the way.
 
I used it as injection. I get that you want a treatment w/o making holes but I couldn't find one. If that is a critical concern then you'd best get hiking up those trees nest snipping! Or look into buying a spray rig and pray for good weather

Have you called around to other local phc people for advice? Siteone in Portland had their finger on the pulse of what folks were using last I checked.
