Oh ever.... the picture appears familiar, although not yet in the form...

The fight at you indoor is of course also really difficult to hardly feasible; what do you do if you discover Thrispe before it's so bad?

Full of empathy, Bernhard.

Hello Michael,

hopefully it remains the case that there are no thrips from eggs...
What do you inject against thrips?

Happy spraying, Bernhard.

even if I have already mentioned the topic one or the other time and it ended every time in a "that's not possible - I'll consider maybe - lyer" I can only say - with useful people this really doesn't happen to the extent - only you can't squirt there and have to stay on continuously...

This year I have even disposed of every insecticide except 2 or 3 means against lice - and absolutely every fungicide - because it is different...

and if the question is still in the room - yes I know what I am talking about ;-)

Hello Michael,

I already work in the botanical garden a while with beneficial salings. I can recommend you an Amblyseius cucumeris / barkeri Mix or Amblyseius swirskii. It is important to use the beneficiallings as early as possible in case of infestation and in larger quantities than the beneficial companies recommend.

Amblyseius cucumeris already fits - in combination with swirskii funktint perfectly - pro bags one calculates approx. 2 m2 culture area - ie you need whs pro application 2 -3 bags per utility type (at the 1st time you take more - because one tears up 1 - 2 bags each and distributes the contents over the plants - so that they are immediately in stock) - and this is repeated 3 x every 3 - 4 weeks - then a rest should be

swirksii also take a few spider mites with you - but you can't really fight the ones with the swirskii - since you need californicus - or phytoseiulus persimilis for arge infest

Hello Michael!
I bring a mix of Amb in spring. cucumeris and Amb. barkeri. The companies usually propose 50 animals per m2... for me it is usually around 300. The whole thing then 3 times every 2 weeks. This works quite well for me, I didn't even have thrip damage to gerbera flowers last year. I make the use as a preventive measure, right after the potting of the young plants of the beds and balcony plants at the beginning of March.
cucumeris eats thrip larvae, barkeri eats soft skin mites (with which I have more problems). It is important that no populations of the pests can build up. You can also try Hypoaspis miles. The predatory mites live in the ground and eat mourning mosquito larvae and thrip sdolls. Since at the beginning of March nothing blooms with me and so there is no pollen there, I don't expect my predatory mites to survive... I get the predatory mites loose in bran and sprinkle them out, but in the greenhouse and not in the living room that would be trouble!
The predatory mites in bags have the advantage that also feed mites for the predatory mites are in it. the predatory mites also multiply in the bags and one has some weeks in which predatory mites come out of the bags. In my experience, bag goods must be used as a preventive measure otherwise it will not work.
Greeting Tom

Hello Tom,

can you still name sources of supply?

Happy growing, Bernhard.

Tom's execution is impeccable - there's not much you can add to that. Only the distance with bowing use can be extended quietly to 3 - 4 weeks - in case of infestation every 2 - 3 weeks.
And jap - the one with the bags is done prophylactically.

For control, simply take blue tablets - yellow tablets are not effective in thrips.

The phytoseiulus can only take curatively - since they would also eat each other up.
The one with the humidity is not so the problem in my opinion.

My recommendation would be - start right this year - an injection with a harmless agent that breaks down immediately - Conserve or Spintor (itself active ingredient - but now knows nimma which is still approved) + 2% sugar and then immediately with the beneficial organisms.

@Bernhard - in Austria you get this in household quantities over Biohelp.at - in Germany I am unfortunately ignorant. I can only think of https://www.nuetzlinge-shop.de/ - but you have to see if the units are not too hearty for households ...

the sprinkled goods in the living room would be a hearty mess - otherwise that would not matter ;-)
they will still crawl around everywhere - but they don't see anyway...

the phytoseilus is really as far as I can judge a bit more "delicate" - but that would be too expensive for me in the private sector - they cost quite a lot...
but the others are more affordable - and also more robust...

and the 2% sugar is as an "attractant / eating incentive" - there are a few tricks when spraying, which are extremely effective - with thrips you should add sugar in case of bad infestation to encourage him to eat - then it works better. because the guy hides otherwise and ev. also makes a feeding break - they get that already with whether you put them on the pelle ...

Well, Martin, you're right... Such

@ Michael - gladly :-)

@Tom - Neem has so far only caused flower damage to ornamental plants (pelargoniums, petunias, etc.) (which is/was the case with almost all liquid remedies) - but never leaf damage. I've never tried this at Amorphos, because I don't use any insecticides anymore. But I'll think of you next time and do a test spray - I assume that won't do anything if you do it early enough.
