How long does azadirachtin drench take to kill whitefly and larvae?

I’ve used this stuff in the past with great success to kill whiteflies. I noticed this infestation just prior to transplant and nuked them just before transplant and still noticed larvae just after transplant do gave them a second massive dose.

About 24h later I flush with water. I check again about 12h later and notice a couple of larvae still

How long does it take for them to die? I know they need to actually starve to death it doesn’t kill them straight up
Just want to make sure theyre dead before I flip to flower and don’t want to give them a tolerance to it before I try another method or rip out the grow and start again

:thinking: hmm - I’d do multiple treatments over a couple of weeks & go from there.

Just guessing :blush:

Sorry for the late reply. I’m dealing with WF. Any luck ridding them. If so do you have a ipm schedule now? Thanks. My grows are trash now. These things turn main stems into barnacle looking dead layer. I’m a mess.

Thank you. My grows are totally lack luster and not achieving maximum potency. It’s been rough. I’m gonna use BTI or mosquito dunks for any FG’s but the WF gotta go. I will definitely pick some of that up. Finally someone who’s been through it.

Do you have a larger grow than a couple tents or larger? Just wondering because I have fans and lights. Not too many (fans and lights, tents) but what did you clean your climate control devices and surfaces? How about vaccuming or mopping before and after?

Sorry for a million ?'s, I just gotta ask before I start buying unnecessary stuff. I’m about to start a new run soon so I definitely wanna clean and paint the next few days. Caulking. Just freshening trying to run some heirlooms and have them look like they should. Thanks for any help again.:pray::grin::+1::seedling::heart:

I got those duckers outdoor there a pain in the ass… I use a combination of canna mammoth control homemade dr zymez captain jack dead bug and bt and a homemade garlic hot pepper spray

Unfortunately I have every cannabis pest out back. It’s just one of those things. I haven’t seen any ladybugs hardly in the past few years. So I’m thinking about ordering some when spring comes to see if I can introduce them back out back bring their numbers up. Over the winter though on my next run I’m going to grab a small amount to throw on my photos just to have some extra security.

I’ve heard several people now say (Dr Zynes?) is pretty good stuff. Most people recommended spino sad to knock out the white flies. I found some concentrated stuff called Monterey garden that people also swear by. I haven’t spoken to anyone who’s had a real serious white fly infestation inside. Outside it tends to be manageable for me if I take the plans to the center of the yard away from shrubbery. Yeah they’ll make their way over there eventually, no ladybugs man it’s really freaking me out not seeing any.

Whatever that dead red stuff is kills pretty much anything. I know its geared to mites but I kills whitefly and is systemic as well. Worked better for wf than azadarachtin drench for me

Do you use a regular sprayer or atomizer when applying?

Azadarachtin drench is in a 15mL bottle that you dilute into reservoir for soil drench

Oh i thought you sprayed the dead red my bad. I do not think a soil drench would kill white fly as they seem to reside under leaf…at least mine do and I have tried most products with little luck seems i can only keep the numbers low but never eliminated. Thanks for the reply!

I do spray the dead red, it’s a different product. That just comes in a spray bottle.

I seem to have managed to eliminate the whiteflies with aforementioned regimen.
