    bali: Thank you very much for the update on the chems!

    berger: Did you get decent yields after the heavy gnatrol regimen? How did they compare with before? Do you mean to say that you entirely got rid of them with that method and that you are getting normal yields now with none of the same problems? Did you have to use the gnatrol again after the first regimen? Did you have plants around that were in in different cycles of life, or just one crop at a time? Thanks!


    Also: EVERYONE who has had them:
    -Please describe the conditions you were growing in (CO2/no, high/low temp& humid, hydro/soil, heavy watering vs light) as extensively as you can
    -Please describe what the damage was (how did it affect the plants? Particular symptoms/deficiencies/indicators they were doing damage) - post pictures if you can
    -Please describe what they look like (if you can magnify them well) or take photos if possible (with really good magnification/macro lens) - it will help to know how many species of these things there are and if they need to be treated differently (I know one thread had BIG ol' suckers that are definitely not what I have)

    Thanks!!!!
    I have plants in diff cycles.... My room is sorta exposed to outside easily and so even if I got COMPLETELY rid of something... they could easily come back...

    YES my yeilds and QUALITY is back.... I use the gnatrol as a PREVENTITIVE.

    Use it heavily and often at first.... it only kills the larve which are the fuckers eating your ROOTS.... not the crawling around ones or the flying ones.... but the only damage they do that I can tell is LAY MORE EGGS.... it takes three weeks for their life cycle...

    after two weeks you will see NOTICABLE results in growth and overall health.. it actually starts immediatly... but does depend on how bad you have them... However it starts killing the feeding larve and they start dying which in turn allows your plants roots to start building again....

    Just plan on once you get the fucks under control... u will still apply gnatrol.... once a week... for a while until u are damn sure they are gone...

    Don't hesitate to use the stuff... it does not affect the plant product...

    It wouldn't hurt to get some good root enhancer like Canna Rizotonic to help your plants get on their roots again... but that is not absolutely necessary..

        EVERYONE who has had them:

        -Please describe the conditions: Soil, standard room, high humidity though! I did not have nearly enough ventilation! Also, that fact also really promoted overwatering by lengthening the time that it took for the soil to dry, so I was jumping the gun without knowing it for weeks, compounding the problem.

        -Please describe what the damage: No visible damage luckily, aside from some possible droop - but nothing that I noticed consciously, I caught them early when I spotted the crawlies in a pot, no fliers had appeared when I started battle with them.

        -Please describe what they look like: Babies/larvae: Very small white bugs that have what looks like four legs, clear/whitish body, crawl around the rims of pots and top inch or two of soil...depending upon numbers they may be concentrated further down into the pot and may be collecting around drainage holes. (Notice, that if you have them at/in drainage holes that there are no visible roots, just yellow/light brown small specks of dying, broken down, roots. Adults: Fungus gnat look-a-like with a bigger, more round, black body; I agree that they are better at flying than fungus gnats and actually present a challenge in trying to find them and 'clap' them down....and the worst part: they don't fall for sticky traps - blue or yellow.

          That's one of the things that led me to believe they weren't fungus gnats.... the yellows were clean save for one or two.

            I had them on my FIRST EVER run, and wasn't clear as to what they were....However, my crop was pretty good in yield and quality...what I noticed worked for me was a combination of the following:

            - Watering my ladies with a little neem oil(only twice, a month apart, in veg)
            - Letting temps drop a bit at night
            - Applying Yard & Garden Safer Brand Insect Killer(which is a blend of insecticidal soap and pyrethrins) on soil surface(lightly, and only on those w the adults) and again on the bottom of my pots where the little disgusting babies that appear to 'jump' congregated....It never got rid of them COMPLETELY(although I temporarily did not see them anymore) but surely did see a decrease in overall numbers. I took the multi-faceted approach cause I wasnt about to let some lil buggers ruin my first harvest!

            It's been months now and I'm prepping the space again...time for some bleach!

            Good luck fellas!

              This may be the most important thread Ive ever read on IC!

              I think you guys just nailed the reason I *always* get spotting and yellowing and leaf death starting mid flower through end of crop. My yields are still good and so is the bud quality but it's driven me NUTS trying to figure out what's causing it all this time. Then this last crop I noticed a lot of dark grey flying bugs with little whitish feathery antennae around the room. After looking up phylloxera on wiki, yep that's the fuckers! One plant ended up dying at the end of the crop (wilted down from suddenly no water) and after pulling the plant theres little worms on the roots that have stripped the protective layer from the root leading to plant death.

              The life cycle of this insect coincides with the leaf damage perfectly and explains why it always seems to start right around day 25 of flower like clockwork. I too have beaten myself up trying to figure out if I was doing something wrong with my nutes or ph but I use a simple nute regimen (Floranova...doesnt get much easier than that). I too also have a slightly exposed grow room and they probably get in that way from fan suction in the room.

              Hot damn boys! I think you nailed it and MUCH appreciation and rep+. I just started out thinking fungus gnats but that's not what they are. Time to work on preventing these bastards in the future. I think Im going to try a combination of Bayer Tree and Shrub (Imid) and Gnatrol for starters. Next crop clones are vegging right now and will go into the flower room in less than a week. Im going to fix this once and for all.

                Seriously spleebale, you have saved my ass big time.


                A)How bad was your infestation and what effects have you observed in your plants/grow?
                I have had these guys for three cycles, but upgrades prior to the current cycle have taken average rh from <20% to 40% or so and I have seen a significant jump in population. Two or three "fliers" stuck to the buds have become dozens. I'm seeing a lot more crawlies on the leaves and containers as well.

                The symptoms were very pronounced, and the infestation actually caused half my strains to hermie right after being moved to the flower room. That was the most disturbing symptom for me, and it is what triggered me finding this thread(which is honestly the best resource I have found regarding this god forbidden plague).

                EARLY SYMPTOM(VEG)
                -Slight curling of some new leafy growth.
                -Leaves turn from healthy green and glossy to a more dull green.
                -Leaves may have tiny red or white specs or larger rusty spots on the leaf margins.

                LATE SYMPTOMS(USUALLY AROUND DAY 25 FLOWER)
                -Some larger fan leaves may develop rusty/off color or just plain sick looking patches and twist or curl and die.
                -Bottom most fan leaves start turning yellow-ish usually fading to the veins like a mag deficiency.
                -Yellowing works its way up the plant like a nitrogen deficiency.


                FINAL SYMPTOMS
                -Plants look ready early
                -Bud quality, size, maturity are lacking.
                -Most heavily infested plants have used up all the green from almost everywhere on the leaves by harvest, even without a flush.

                B)Have you grown the same way before with success or with the same problems? Have you grown a different way before with success or the same problems?
                When I was working with a less humid room(15%rh), I was getting okay harvests of respectable quality, but the plants really prefer 40%rh to 15%rh so I tweaked my room... well the aphids went nuts; there are fliers stuck to buds, crawlers all over the leaves, and I assume plenty of larvae suckling on the roots.

                These parasites have most certainly been effecting pretty much everything about the final product. However, it seems like they prefer some strains to others for some reason... or maybe some strains are more resistant to the pathogens that are tryin to infect the open aphid bites. Since I was running multiple strains, I was still getting some real nice quality buds from the plants the aphids decided they didn't like.

                C)Have you treated them before (if so, how and what were your results/conclusions)
                I just treated them like a week ago after finding this thread. After a complete foliar spray and root drench with Spinosad, I am confident that Spinosad works to reduce numbers on the leaves, roots, and in the air... I plan on combining the Spinosad with Botanigard ES. Basically my plan is to make my containers a real hostile place for an insect to live; deadly fungus on the prowl in the coco, Spinosad clinging to the roots ready to poison any biters. God I hope this works...

                EDIT: SPINOSAD IS NOT EFFECTIVE FOR APHIDS: I DO NOT RECOMMEND A SPINOSAD ROOT DRENCH.

                D)What type of medium/nutrients and what type of setup (hand water, ebb/flow etc)


                Canna Coco
                SoulSynthetic + Earthjuice nutrients
                Handwatered

                  spinosad doesn't work on suckers, and all aphids are suckers.

                  fail-proof way to get rid of them is to dunk whole soil/media container in a mix w/pyrethrins and an effective wetting agent. Every container. Then repeat in around 4 days to break the breeding cycle. Then wait a week for the potential dormant eggs and repeat. Then repeat again in 4 days. That should do it. Major PITA, but it works. Nowadays I just dose my moms and babies w/ Merit.

                    I am absolutely certain that there are fewer leaf crawlies on my plants a week after a Spinosad spray. They were everywhere and now they are hard to find. I've also been letting my coco get real dry between waterings, but I doubt that had much of an impact on the leaf crawlers?

                    Is there a pyrethrin product meant for garden use? Or do you just use the stuff thats meant for dogs? My one part nutrient contains Yucca extract, and I've got a bloom booster that is mostly yucca, but I can only use 12.5ml/g and 5ml/g respectively is that going to be enough "wetting agent" if I just mix that up with it?

                      Great info here gang. I have had them for the past 2 weeks, punks came in on a clone. No damage to plants yet but there numbers were increasing until....

                      I hung up a Hotshots no pest strip 2 days ago, they are dead. No more fliers and even the crawling aphids are dead. I had to vacum the bodies off of the plastic that covers my tables this morning. There wasn't a single insect flying in that room today vs. yesterday when wave after wave of winged aphid would ascend to the light. I will report back if they re-emerge. Good luck everyone, these bugs suck.

                      EDIT: Does not work on the ones in the pots, but does keep them from spreading to other plants. I am using Imid to get the ones in the root zone

                        Both the act of spraying and the spray itself may have slowed down your aphids, but it was not the spinosad component. Spinosad has to be ingested to be effective, and aphids insert their suckers straight through into the leaf or stem.

                        I used to buy Bug Buster-O but it's no longer on the shelves in CA or OR. It's been replaced by a product called "Pyreth-It" that NGW distributes. Check your hydro shop or order online.
                        As far as the yucca goes IDK about yucca as an effective foliar wetting agent. Also, the two things you mentioned have food in them which is a no-no for foliar apps w/ pesticides. Use a drop/gallon Palmolive soap if you don't have anything else. I use wet betty or penetrator.

                          From the research I did I learned that these bastards get winged form only when the infestation of one area is too great. They grow wings so they can "spread out" a bit and infest other areas so once you have the winged one your best bet is to clone or you will be dealing with them for a long time.

                          I had a bad infestation of these last spring and had to clone everything and start over.... Unfortunately I live in Cali and have seen these things in my yard! I guess wine country has it's pro's and con's....

                          BTW, I also tried Zero Tolerance (first as a foliar then as a root drench per the companies directions) which didn't do much but piss my plants off more.

                            Another identifying feature of these things are that they have cornicles (2 raised antennae looking things) on their backs. Use a 30x or greater scope or loop for you to see if they are definately aphids.
