Before trying to enhance the microherd (rootgrow) and symbiotic relationships (essence & tricoderma), if the thrips attacked I declared full scale chemical war on them (ala Saddam Hussein) using Scotts Bugoff.

After trying the organic techniques, the thrips still appeared, but I read that chemical attack would destroy the microherd / symbiotic relationships.

After the last attempt was heavily infested (1-nil to the thrips) am thinking that perhaps it would be best to declare a fullscale chemical war, and not worry about the fungi / relationships. Or at least start them afresh after.

Thought had cleaned the room well this time round inbetween, but 1 week into flower they are back.

Any advice? spray them, or ignore?

5 yr shed grower here when you know please let me know
thrips 5yrs me nil
i have tried everything but they just come on back

Have you tried garlic ?

I have no idea what you mean?

Throw some bulbs in there?
Eat lodas and breath in there?
Smear it on the walls?
Make a weak garlic water solution and mist em?

i use plant vitality http://www.uk420.com/boards/index.php?show...60&start=60
pic at the bottom of that page

have you tried that ?

Seriously though, I was reading about Garlic and thrips on a non-ganja related gardening site not so long ago. Can't remember much about what it said though. Not something I've had to look deeply into, thankfully.

Hi all

Greens sell one product ( errr yellow fluid ) works well IMO

gets rid - but like you say they come back

In the compost me thinks

Been using pot covers in veg - helps i think

some strains are resistant and some a night mare

hb

so using Bugoff and a nasty chemical attack is a no no?

Will give plant vitality a go, that thread seems to praise it

a little crushed garlic (2 gloves), a little hot chilli powder (teaspoon), pint of water and splash of milk, mix well and leave over night then strain off and spray (just before lights out), works very well as a contact killer for the buggers.

you should also make a habit of checking your plants as often as possible.

good luck ....................

Hey rip! Good recipe man. I have made a note as my 1 week into 12/12 clones have just been badly f****d by thrips so I gave them a good drenching with a Bug Clear gun (Scotts). It did not feel good at all, using such a harsh treatment, but 2 days later all the bugs have gone and the ladies look a lot happier.

If they come back, I do not really want to use chemicals again, especially during flowering; also I have started using Plant Magic Essence, and as Sharkjazz said, it can't help the symbiotic relationship/microherd factor, so I will try the garlic/chili/milk spray ... although, might there not be a chance of a problem using milk? ie; smell and bacteria?

hi ya zappa hope all is good with you

milk is cool dude as its diluted well in the water and will cause no problems at all, just a splash or a table spoon is all you need
the trick is to be on a constant watch and nip them in the bud before they take hold ..........

................

Well you did say you tried all organic remidies, so I figured you may have used the garlic treatment as that has been mentioned on the board before and is a well known common garden pest control.

But yeah as foliar like rip has provided details on how to make.

Ive been using garlic barrier on my plants which I got from a garden centre. It deters pests and is a bio stim too.

Sorry if wasn't clear. Haven't tried any organic remedies. Used to use Bugoff before trying to build a strong microherd / fungal relationship in the plant. Since then I have just ignored the thrips and let them do their thing, which seems to vary from full on destruction to kind of petering out

I have been thrip free now for 3 years and I’m an all year indoor grower, the way I got rid of mine was to first research the knowledge base and pest forums for as much advice as possible and I found then that the only pesticide us hobby growers can buy that has successfully killed all thrips in an indoor canna grow room was Scotts Bug Clear at maximum strength, mixed with horticultural soap at maximum strength. I then brought each plant into the bathroom and absolutely soaked them top side and under all leaves and I soaked the compost, you cannot afford to miss even one leaf, I mean drench them, I did this 3 times over 6 days (every other day) with 5 fresh litres made up each time in my mister/sprayer for a 2mx1m room with 24 plants. After harvesting I totally bleached the whole room, every single cm was cleaned down with bleach and very hot water. This happened about 3 years ago and I’ve not seen them since. I did not want to use a systemic pesticide but it’s the only way to eradicate them successfully.

Ot1 said that if you get thrips, you should hit them with max strength pesticide as above, but if you only do it half heartedly and don’t fully sterilise the room straight after harvest it’s possible that you can create a super thrip colony that is totally immune to all chemicals available to us from garden centres. I know I would have been in trouble if this had not worked for me; I would probably still have them now because I could not stop growing.

There is no organic pesticides on the market that will kill thrips.

Peace,
GG

This is what I was fearing.

as jiffa says plant vitality is spot on , alot of ppl are bangin on about it , i had thrips i think recently
went to ma local grow shop they suggested plant vitality sayin it was flyin of the shelf so i grabbed
one , sprayed the fuk out of me girls , even washed ma room down with it , 3 weeks now and no sign of any pest
attack , give it a go mate

The only problem I see with this Plantvitality is that they say it's safe to use at any stage of growth when it is not, the disregard BAC has for the safety of it's consumers is staggering

Scotts Bug Clear mixed with horticultural soap at max strength is the only pesticides that works if done correctly the first time. But I would not treat plants with bug clear if in late flowering, harvest and then spray every thing.

Peace,
GG

fair point mate , but surely you should eradicate the problem before it gets to late to treat
obviously some cases are different , but the majority start from an early age giving enough
time to sort the problem out before puttin on 12/12 , and the plant vitality seems to be the
number 1 pest control at the min , i remember usin somethin called dynemec years ago , think
its illegal in this country unless you are a registerd grower for a big supermarket store etc , anyways
man take it ez

Heya , i brought a tomato plant into the green house that had previously been treated for Thrips with Abamectin , they re appeared on that plant and spread to another seven weeks later . I previously used Bug Clear (rapeseedoil) for fruit and veg on a fungus gnat infested cucumber plant with little of no effect , in a plastic cream pot with lid , i crushed 1 clove of garlic 5g or so of bacci (may have been some plant material contamination ) and one tea bag , left for a couple of days mixed in with one ltr water and the recommended 20ml ltr of bug clear . Three weeks thrips have just shown on the secondary plant not the original and not spread to any others in there so i will be spraying again after the weekend , i personally would certainly consider using this inside , as and when , good luck .

Hiya TS,

But that is the main problem with thrips, they become totally immune to every pesticide if not totally killed off within the first few treatments weakening them each treatment until they have been eradicated, you have to hit them with the strongest pesticide you can get and hit them hard, fast and regularly or you end up with a super thrip that cannot be controlled with pesticides available to us hobbyists.

Peace,
GG

Heya , totally agree GG , but finish plants within three or so week to go and the then chance to totally deal with the enclosed space with what you see fit , i would certainly consider , even more of a problem on over wintering outdoor crom/lets , im afraid im still to find a friendlier option to myself on this than Abamcetin good luck .
