Beware that using any foliar application that is acidic brings with it the potential for powdery mildew. PM likes a acidic environment. This is why many common treatments for PM include the use of an alkaline foliar application such as potassium bicarbonate. Knowing this, it is imperative to control temperature and humidity after the foliar application to prevent a PM outbreak. PM spores are always present except perhaps in a professional "clean room".I just read this:
"Can I use vinegar to kill aphids?
Get out a spray bottle and fill it 1/3 of the way with distilled white vinegar and the rest of the way with water. This will kill the aphids and larvae on contact. Place a square of aluminum foil around the base of plants affected by aphids. ... It is also good for the plants, as it brings them more natural sunlight."
It's certainly worth a try, thanks!

I'm going to blast them with shitty music. Britney Spears or Taylor Swift. That'll teach 'em.Try talking to them... see if you guys can come to a mutual agreement or some sort... perhaps offer them a new home or venue to gather at... silly lil critters
I never had PM in missouri, grew there for like 23 years. Came to colorado and bam, PM. PM needs times of dry and wet, it likes RH% fluctuation.And PM in Colorado, totally WTF
If you can, take the water hose and gently spray the bottom of the leaves, knocking them off. It's a balanced not too hard, not too soft
This ^^^^^^^^^^^
I wouldn't spray anything organic or not on flowers that far along. If you have one of those handheld shower heads put them in the shower and spray them off with plain warm water and then put the plants in front of a fan to dry off.
But you really should keep a better eye on your plants. An infestation like that doesn't happen overnight.
The "golden years"Fuck it sucks getting old!
Permethrin will pretty much kill most things, spray and do a drench.if your heavy into flower you can always wipe down the leaves by hand, its a ball ache but possible. Soapy water will slow them down and somewhere on here theres an organic chilli based recipe for flies mites etc thats supposed to work and can be used in late flower.thats one of the worsed cases iv seen . good luck!

When infestations get real bad some aphids grow wings to fly to another plant. That's a crazy amount you have there. If you treat your seedlings with Imidacloprid next time the aphids will starve and die off. There must be some vegetation outside your house that is rampant with them though. I would treat those plants with imidacloprid also and release green lacewing larvae.Well, gonna finish up on this thread, thanks to all that contributed. I destroyed most of the crop; the infestation was too overwhelming. Tonight, I noticed all this on top of my HID light. WTF?! I thought flying aphids were quite rare. This is a shitload of them!

I have fruit flies sometimes. That ain't it.

They can come in on clothing or shoelaces or hair unnoticed . All it takes is one, because they give birth to live young and don't have to lay eggs to reproduce. They breed fast af. Neem oil won't kill them off completely in my experience. It will help keep them in check but you're gonna want them gone before flowering especially because they shit out a sticky white secretions in bud crevices and cause black sooty mold. Order Adonis 75 and be done with them.
