Spidermites 5 weeks into flowering - predators the only solution?

[2bags]

Hi icmag,

Just wondering if anyone has any advice on how to rid mites at this stage of flowering.

I think it may be too late for neem oil.

I've been recommended Hot Shot No Pest strips but I can't find them where I live (Europe). Tempted to order online from the US.

Does anyone have any experience with predatory mites or ladybirds?

Any advice would be greatly appreciated. Thanks a lot.

Mighty wash will work. And you should order the no pest strips they work awesome.

2,
Below, I've copied my Spider Mite Control doc. Where I mention Azasol, Spinosad, or whatever, substitute Insecticide Soap, since you're well into bloom. After the 4th treatment, release the predator mites. This should at least keep their numbers very low till harvest. With this, you won't be smoking chemicals. BTW, No Pest Strips give off toxic vapors that you will breath while in the room. Keep us informed about the outcome. Good luck. -granger

I would use Azasol rather than Azamax or Azatrol. Azasol is oil free, causes no phytotoxicity, is more systemic, no smell after drying [to humans], no mess, similar price, dissolves instantly. In sum, more effective.

Best way is to mix in a bucket, cover top of root ball with a rag or cardboard and immerse everything above ground. That way you get 100% coverage, and dunking them washes off many mites and eggs. Also, spray walls, doors, floor, entire container including the bottom. Non messy since it's oil free.

The big key that has given me a once and for all kill [till I carry more in], is to do a second dunk 36 hours later, followed by another in 48. This kills any hatchlings before they have a chance to lay more eggs. Plus you're done in 4 days. I usually follow this procedure using Spinosad w/wetting agent the first 2 treatments, with Azasol for the 3rd.

What has worked well for me has been to spray the plants with Azasol during the first week of 12/12 as a preventive. No mites thru harvest. Haven't had mites in the 2 years since I started this one preventive treatment.

I've also gotten rid of mites using only Spinosad w/wetting agent for 4 treatments. Spray, again in 36, 36, 48. Good luck. -granger

i spray neem oil up to week 6 without any issues, 3ml/litre of PURE neem oil will work for spider mites...

good luck

Take the plants out an hose them off every other day. You can just wash them off. Then spray the room.

Also trim up any lower branches an anything close to the stock. They can hide better there. Trim any curling dying leafs.

You can use a product named envidor from bayer.. it's very effective!

Thanks for the help everyone.

Before I was able to read everyone's responses I took the plants outside and high pressure hosed them upside down.

I let them dry off and inspected the leaves and buds. I spotted one or two remaining mites but it looks like the majority got blasted off.

I'll keep you all updated as to whether they return!

Once again, many thanks for the helpful responses.

Good option! I've heard but never did the vacuum cleaner works. Other than the water blast, I only did essential oils (stuf like rosemary, clove, etc) this late, but not neem. I think the water blast is under rated and mites like it dry (low RH).

So far it seems to have worked a treat! I inspected them last night for any eggs that may have hatched since the hosing and found one or two, but other than that they are looking pretty mite free (touch wood).

One thing I noticed is lots of very fine black specks on some of the older mite damaged fan leaves; I assume these are dead mite carcasses or the remnants of hatched eggs? I can't seem to wipe these off so easily... any idea what these are and whether I should worry?

Thanks IC - really appreciate the knowledge.

In future I will grow rosemary alongisde all vegging and flowering plants.

It is quite possible you also have thrips. They leave feces that are like what you describe. First time I found I had them I didn't know I even had em. I also had spidermites and it wasn't until I noticed the black dots and then a little light green thing that scurried fast into the crevice of a leaf. Spinosad worked wonders and they were gone in no time. Captain Jack's Dead Bug Brew (contains spinosad)is really cheap and works really well. It's also really safe to use. Its a by product of a bacteria.

Not sure if just growing the rosemary will work. But it sure goes well with many dishes.

Spinosad is something you can use on food crops very close to harvest. But the great thing is you don't have to spray the plants. Drenching the roots will disrupt their cycle by killing the stage that's in the medium. That's probably all you'll need to do for thrips if you have them. Also, for whatever pests you have, total kill would of course be preferable, but you only need to keep their numbers low till harvest. A small infestation will cause little damage, and you should be able to get a good harvest.
Good luck. -granger
