    Hi is this a fungus gnat? I used time release composted chicken manure and put on top.

    The worm photo is a long wet gross worm, no black head but I might look again.
    Its 100F every day the soil was dry, I had to water just now so thats why its wet although its obviously way to damp over all.
    And yes I have flying bugs but hard to get them in my scope to photo.

    Using dunks constantly, with every watering, I have very few flying gnats, but tons of them in the run-off. One reason I keep wanting to give up coir and go back to flood and drain hydroton.

    I believe Vectobac WDG is the same product as Gnatrol. yes, it's great stuff, without it I'd probably have to use nemotodes which cost a lot more.

    There is a product called Vectobac WDG that leaves all others for dead for ease of use and for cost.

    It is granulated Bti that will store for 2 years and costs about $200 for 500 grams.

    Some hydro stores sell it in smaller quantities packaged in their own labelled containers, usually $80 for 50 grams.

    You use 1 gram per 2.5 gals of water and apply three treatments over three weeks at 7 day intervals.

    I totally eradicated fungus gnat from my grow earlier in the year using this product. They've come back again and I'm just a few days away from the third and final drenching and I don't expect another infestation in this grow.

    To put things in perspective: Gnatrol has around 3 grams of Bti in a bottle. That's around $1.20 worth if you buy in a 500 gram tub of vectobac wdg.

    I highly recommend treating fungus gnats with granulated Bti.

    Peace

    The dunks work fine to administer Bti but they have some ingredients that are not organic. Gnatrol will keep you 100% organic. It's a digestive parasite for bug larvae, it won't affect the health of the soil bacteria.

    The Gnatrol powder loses its effectiveness over time, I find after 6-12 months in storage I need to use 50% more which sucks, it's expensive. The old liquid version used to store in the refrigerator and stay potent for a couple years.

    Neem works great but if you soil drench with it the plants will suffer. D-earth or sand on the surface works good too but can be hard to maintain.

    i grind the dunks up in a coffer grinder and top dress couple teaspoons per plant and works that way for me

    I Think the problem with dunks is that they are often mis-used. Im pretty sure it takes a while for them to break down if you will and start to do what they do. Once they do get to work, I believe they are only effective for 4-5 weeks. I think adding the dunk crumble in stages may be a better approach.

    Im battling with these little fuckers again this round. I have sticky traps but it appears the hypoaspis miles have disappeared. I could get more but I am wondering if I should try gnatrol? I have read that SM90 wipes out the microherd too so I dont want to go that route though I do have a bottle. Does gnatrol wipe out beneficial bacteria as well?

    Topping the pots with sand will be my last resort but I know that works, just looking to try something new if it works. The Hypo miles are about $35 CDN pesos delivered.

    People make choices based on possibly incorrect information.

    Ego plays a part as well.

    SM90 is good stuff.

    Ook.

    Let's try this again.

    I am contacting any producers of Bti products to inquire if they sell a live product or viable spores.

    If you use a product not listed below, post it and contact the producer. Or just post and I'll do it

    Gnatrol (Valent) - emailed

    BMC (Ecological Laboratories) - viable spores. Had to pull a few teeth for a straight forward answer.

    Mosquito Bits/Dunks (Summit Chemical) - previous inquiry, no viable culture/spore.

    Bti WDG (Golden Harvest Organics) - emailed

    Just stopping in to say I been using the moskito bits for a couple run's and I just keep sprinkling a bit on when it looks like it washes into the coco. And I have not seen a flier in a week or two. It has kept them little fungas knats to a flier or two tops. It seems to work the best when the humidity is arund 50% or so and the stuff starts growing like white webbing or fuzzy stuff.
