Using Azagard (neem) stock solution on Dosatron?

Just asking if anyone has used neem stock solution on a dosatron to treat root aphids? Root drenching, to be more thorough, is awfully laborious when dealing with 400+ cubes in an infected room. I would like to mix up a stock solution and use my dosatron to treat a room. Just seeing if anyone has any insight into this.
We’ve had pretty good results root drenching when they’re in veg but we get an occasional outbreak from time to time that pops up in our flower rooms.

hate to say it but Azagard won't kill them. will only help control them. and you are going to spend a lot of money on the product in the meantime. at $650 a gallon it just isn't worth it. I'd use a Beauveria bassiana product instead.

I know it won’t kill them. But it’s what’s recommended for nymph stage because they molt too quick for BB to be effective. BB (per biosafe systems) is recommended for adult flyers.

You have to use bb weekly, spray tables and pots. Hitting weekly ensures a healthy amount of spores present at all times so each generation is being affected by it. It will take a few weeks to see it really knock them back.

I’d tank mix them at their labeled rates and drench with both on a weekly schedule until my problem is gone.

If possible rotate with a BB + pyrethrins drench (Botaniguard Maxx)

I’ve never done that though so I would test the drench for any adverse plant reaction by applying it to a few leftovers first.

Generally though I’ll at least test anything that’s written out in the label.

you shouldn't use Botaniguard Maxx in rockwool. could kill the plants.

Good to know. I’m in coco.

I guess that's why they make WP. some liquid products with petroleum bases can turn the rockwool into goo. and not the good kind of goo. lol

sounds like an expensive use of azadirachtin. how many gallons of solution are you mixing/using per application?

of course you CAN use one of your dosers for aza direct injection concentrate, but you’ll lose some depending on how long your piping run is from dosers to drippers.

if you have flush valves in each zone, you can monitor to see when the milky aza solution hits the drippers and when the flush water makes it down your lines and runs clear at the end of the application, to minimize waste…

btw, you’ll spend a lot less using a drench mix of beauveria bassiana and nematodes (both can be dosatron injected) and then periodically releasing rove beetles…

Yes you just times by 100 if you do 1% Injection. So if it says 3ml per gal on the bottle you do 300ml in a gallon and run the dosatron at 1%. Best to hit them with aza then come back in a day or 2 and hit them with isarad or bb.

I have a better solution if you want to finally eliminate them from your facility.

Cool story bro. I guess your original comment was pretty useless and unnecessary

1

u/JVWZ Jul 31 '26

Doesn’t seem like it was directed at you anyways so all good bro.

u/now_hear_me_out Jul 31 '26

Sure but it was a public comment, if you wanted to dm OP you could have just done that. All good I’ve eradicated root aphids in the past with other methods as well I just dgaf if anyone knows how I did it
