Well I thought I had some pesty fungus gnats, a put some perlite and cinnamon on the soil. Had fungus gnats before just let the plants dry really good and then used the perlite/sand and gone. this time, I was wrong. the shriveled buds on the new jamaican seeds I was testing I thought was a thing they did or some shit or maybe some high humidity fungus or some shit, got the scope out and its OBVIOUSLY thrips. little worm looking fuckers on the leaves tiny and gross as fuck! so the treatment (perpetual grow so I'm shitting myself right now I can't wipe out and start over!!!) is what spinosad for the leaves and .....something for the dirt...but what? Anyone use mighty wash for this? I had some so I coated everything plants dirt walls every damn thing with mighty wash because lazy grow store guys don't open on sunday and I'm freaking the fuck out! Any and all help appreciated! This should be a great test for the fucking organibliss too huh? really hope that shit works now!

Can you get a pic of the pesky buggers? I use spinosad foliar and on the top layer of dirt as preventative and never have any issues with them.

I can't-I can only see them thru my scope and it's the radio shack shitty scope no way I can take a pic with it. Pretty sure they are too small for my camera as well. tiny tiny little wormy larvae on the leaves. sucking the life out of the buds

Management:

Due to their small sizes and high rates of reproduction, thrips are difficult to control using classical biological control. All predators must be small and slender enough to penetrate the crevices where thrips hide while feeding, and then prey extensively on eggs and larvae. Only two families of parasitoidHymenoptera are known to parasitize eggs and larvae, the Eulophidae and the Trichogrammatidae. Other biocontrol agents of adults and larvae include aphid wasps, anthocorid bugs of genus Orius, and phytoseiid mites. For this reason, many growers are occasionally forced to make limited use of pesticides to control thrips populations in the field and in greenhouses. Another effective strategy for pest thrips are biological insecticides, including Beauveria bassiana or Verticillium lecanii. These demonstrate a clear effect on eggs, larvae and adults of thrips.

Buy anything containing spinosad, apply every 72 hrs for 2 weeks. they will never come back.
(i fought thrips ineffectively for nearly 2 years before i was able to get my hands on spinosad, works amazing.)

btw thrip damage is easier to confirm vs actually spotting/identifying the thrips.

look for the classic tell tale signs of a shiny silver sheen on the top of leaves with a lot of pin head sized black speckling.

yeah it has macro but these are so damn small. I can't see anything except the larvae little wiggle worms. Cant find any in the stage the man posted. lots of fungus gnats on the fly paper but nothing looking like that. oakley; did you just treat the foliage and let the medium go?

looks like this. its the larvae I can see not any other form of them. I have never heard of fungus gnat larvae eating on plants in the buds.

Had these buggers a few years ago. One of the guys at a local store gave me a free sample of the Organabliss?, the same stuff you are testing in the other thread. Diluted and sprayed on a few times and never saw them again. I may have used a soil drench too, not for sure.

I lost an entire pan of 7 week in flower, Bubba mothers to thrips in just 72 hours, ugh. They were so aggressive it was not something I was prepared for. By the time I actually saw them my plants were dying.

I felt so guilty.

The second time I got them I was prepared and I sprayed immediately with Spinosad and sprayed again after a week. I also mix in the Spinosad in with Safer Insecticidal soap and luckily I haven't seen anything alarming since I started spraying prophylactically with soap every other week.

In my veg room I spray them once when they are small and again just before they go into flower with the Spinosad/Soap mix. So far my room has been clean ever since ::knock on wood::

Good luck on your battle with them,

They seem to come here every spring from what I have heard. Spinosad will get rid of them, Also look into neem cake to add to your soil it should boost your plants defenses to most problematic bugs and won't leave the neem flavor behind like neem oil will.

yeah dude, foilage spraying will kill them just find, spinosad is systemic (it will work its way into the plant and live there, when the thrips feed off the plant, they die <3)

OH and just so you are well informed. Thrips build resistances to 99% of conventional pest treatments extremely quickly. neem, pyrethrin, permethrin, piperonyl butoxide, potassium fatty acids, azamax, dichlrovos ... all useless against thrips, they just come back :)
