A search for nilgnat turn up no results, on google.

also gnat controlling products (gnatrol) don't work on root aphids...

anyone else have any ideas?

try a google search for "nilnat"

i spelled it wrong. my mistake.:yoinks: also with gnatrol try and double or tripple the dose.
i used gnat off and i used it 5 times the strength and it worked pretty well but did'nt clear them up.

once you got gnats you wont get rid of them iv'e still got them:wallbash:

well thats my experence. i use sand with every pot. and i still get a grow together:joint:

that there is a commercial landscape product for systemic control of sucking insects. Don't poison your peeps. Your Better of with some Diotemaceous earth.

here's the merit 75 wp details online here: http://www.gainvasives.org/hwa/merit.pdf
page 4 details = 1tsp/10g....

i was top feeding so i fed until i had 25-30% runoff... like i flushed with the merit solution. 1 time was all i needed

regarding usage in an ebbnflow/grow platform.... personally i would add it to the rez with plain water to the desired dosage and flood away a couple times. You may want to also go around to each container and give them a nice top fed dose too... just to be safe.

don't know if you saw this from kushism (where you at man?)
Personally I used merit, 3 1/2 teaspoons in my 35 gallon res. and ran the drip sys, and also handwatered from the same res to ensure full soaking. I noticed nothing living in there, crawling or flying after 24 hours. 14 days later and still no signs of anything alive, and nothing dead draining into the resi anymore..

and i am pretty sure this is what Dr.G did:

1 soaking for an hour or 2, and then drain.. i don;t think there is any reason to rinse, just start hitting them with nutes again...


humbleguy (and anyone else with root aphids), you need to go check out this thread here: http://www.icmag.com/ic/showthread.php?t=70503
read thru it and try to relate since you have not experienced it. these thing suck the life right out of your crops. bad bad bad news.
unless starting the garden completely over FROM FRESH CUTS IN NEW MEDIUM there is no way to get rid of these suckers save the nuclear blast.

If your worried abotu merit 75 ... just know that its used up until the day of harvest in california on grapes and pecans so i would say that it dosn't transfer to the upper portion of the plant..............

thanks greyskull! Gonna kill those buggers now

diotemaceaous earth

diotemaceaous earth

per wikipedia-

diatomaceous earth is 86% silica, 5% sodium, 3% magnesium and 2% iron.
Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae. It is used as a filtration aid, as a mild abrasive, as a mechanical insecticide,

I would flush with this being careful of the sodium content. Imidacloprid has a mean residual and who knows what it becomes oxidized and combusted (burned up into your lungs)

oh, and notice the %86 silica :yes::yes::yes:

It's an ornamental systemic so I don't see what would stop it from translocating to every part of the plant once taken up by the roots.

Not sure I'd want to smoke a neonicotinyl . The app rate is pretty low so it's pretty potent. Not sure if heat combustion neutralizes it but if it gets into your blood stream humans do have the same receptors as pests have that this chem activates.

Systemics and ingestible plant matter always seem like a bad idea to me.

supposedly it is systemic for 90 days; i don't have the link to that magic date in front of me but that's what i remember.

as far as root aphids go this stuff is the atomic bomb; kills em in one application; the systemic nature of the product is what keeps them from coming back; it gets absorbed by the roots and then anything eating the root absorbs the poison etc... i use it only when i have to and i allow 90 days before harvest if i do have to use it

i would say that it is great for moms and anything coming into the garden if you're worried; root aphids are nasty and there are some local shops that store their soil on the ground; i've seen a new bag of soil kill a garden before with all the crap that got came along for the ride

my friend recommended azamax as a organic soil drench at one ounce per gal to kill the root aphids but i don't think that'd work in a rdwc system; nor do i think diatomaceous earth would; maybe if it was a different medium setup... then again my friend is still battling fungus gnats and other bugs so your mileage may vary


what avid/floramite is to mites merit is to root aphids and then some


oh yeah... if you don't like systemics and ingestible plant matter stay far far away from that produce section in the supermarket.... i live near a lot of very large 1000+ acre ag ops and the stuff they spray can put an unlucky work crew caught in the field in the er after one pass; you think those 100 acres of tomatoes next to those pecans that just got overspray are going to be tossed in the trash or put up for sale?
