Found some white spots yesterday on my babies (2 and 3 week old seedlings), so I came to this thread to see if it was sumpin serious...oh crap, apparently it is! Hopefully, I have found a solution, but time will tell.

I tried Volk Oil Spray concentrate (Ortho brand from Home Depot) that I had previously used on a small mango tree in my yard (which seemed effective on it). This time, I used it at half the recommended strength for greenhouse applications, and misted it all over (& under) the plants, and the entire veg area too (a shower stall) last nite around 8pm. Prior to that, I made sure they were thoroughly watered. Left the fan on to ensure adequate ventilation, and the temps were 76-79 degrees farenheit (under the CFL's).

Well, it's been 24 hours, and so far, so good. As far as I can tell with a magnifying glass, the borg seem to have suffocated, and no visible signs of leaf burn (my greatest concern). Full strength would have made the leaves shiny, but half-strength didn't, so I have hope that they will be able to withstand it. It may not have been the optimum solution for this type of crop, but I wuz desperate to get them critters eradicated as soon as possible. And I figured if these tenderlings could make it through 1 application ok, they would be allright down the road at harvest time. But I would not recommend it for use during the flower cycle, as it's 97% petroleum oil based.

It is listed for Whiteflies, Mealybugs, Scales, Adelgids (wtf?), Lacebugs and Spider mites, (as well as their eggs). I'll report back if any adverse signs appear...

Also, while looking online for other methods of control, I came across a product called "Agrizyme Natural Pest Killer" for Spidermites & Aphids listed at 4hydroponics.com ($9.95 for 16 oz. spray bottle). If anyone has any experience with this, let us all know how it worked, please...

Heyya Reef. You have to be careful what you use on young plants. I just lost a bunch of clones and seedlings after spraying with a clove oil-based spray. The half strength was probably a good idea.
Are you sure you have mites? Thrips can cause similar damage, but they have a different feeding pattern.

Here are some pics of an early spider mite infestation:

Reefdoggie · 10-22-2008, 05:05 AM

Weedninja, I think they wuz mites, based on your pics, and others I've seen. But I am a mere neophyte and prolly wouldn't know a mite from a thrip. Do thrips spin webs too? I forgot to mention there were a few of those at the base of the leaf stems...but I think I get 'em early on before all their relatives moved in. If not, I'll chalk it up to a noob's learnin experience (at least its bagseed).

Oh and thanks for the tip on clove oil.

Weedninja · 10-22-2008, 09:46 PM

Well, you're guilty of not mentioning that you had webs and I'm guilty of not mentioning that webs are the #1 sign of spider mites.

Just remember that most mite treatments don't kill the eggs, so a repeat treatment is necessary around a week later.

High all, I would like a definite answer, from anyone who knows, can floramite be applied in late bloom(7 weeks out of 9)? Go away for a little while and they move in. Not nice! RR

Weedninja · 10-24-2008, 08:19 PM

Not unless you don't mind smoking floramite.When I have mites in late flower, I mist the plants with water once a day or so to keep them from setting up shop. It's not a cure but it will keep the population down enough to prevent them from wrecking your grow.
