thrips in a scrog

I've got 5 plants in a scrog in a drobe. They're 5 weeks in flower and things are very dense in there. Unfortunately I've realised the thrips I thought I'd got rid of a few weeks back are back with a vengeance.

I've tried using tutu's c02 method a few times but for some reason its not working. I've got some SBPI which I previously used, but I didn't find it that effective the last time I used it. I'm willing to try it again but the problem is avoiding the buds and only spraying the leaves.

So is there an alternative to spraying or do I need to get on my hands and knees and spray individual leaves?

Cheers folks :blub:

For thrip I use a neem oil product called AzaMax (General Hydroponics) which works quite well if used correctly (applied every 3 days for about 12 days), and is very safe. However I don't think you can get it in the UK. But there may be a similar product out that a ways.

The active ingredient is azadiractin, a neem plant derivative. Omri certified. Google is your friend.

Nematodes are also helpful and not toxic at all.

thanks fella, kind of you to drop in with sympathy and luck, what no tea though?

thanks for the advice rand, I'll see if it can be put to any use this side of the pond.

Just to add, I have read most of the thrip threads and the knowledge base, but its left me more confused than I was when I started. I'm just worried about losing what looks like my best crop for years, all pinball wizardry too.

SBPI looses it's effectiveness over time, go for a contact spray based on pyrethrum or buy some new SBPI :ouch:

Good advice, I had a massive infestation of Thrips at week 4 flowering.

I used This for about 7-8 days (everyday) and it knocked the Thrips back to less than 2% population.

Well that would explain a lot, cheers fella. So much for their 'long shelf life' they like to advertise, I take it 3.5 yrs is beyond the recommended long life.

I guess population control is better than nowt, ta for that.

yup, 2 cats and work with dogs, could be that. Can't afford an ozone generator right now though but can afford washing up liquid :ohmygod:

SO the Pyrethrum and SBPI are ok to use this far in flower and won't effect the buddage, or do I need to coat individual leaves?

Sorry man, that's not really my area unless it's UV

Oh yes geez, that's probably well past it.

Neither are systemic but contact killers so you should be fine ;)
