Trauermücken während der Ruhezeit im Sphagnum

Hello together,

checked today my A. titanum tubers stored in Shpagnum; and Lo and behold: there some Sciaridae flew towards me! I then searched the tuber with thread counter I found some larvae at work at the base of the tip and root approaches!
Did she then vigorously washed off and now is in an Axorisbad (thiamethoxam). After 15 minutes I counted 13 larvae at the bottom and on the solution surface swim.
There are even small white root tips and so I will pot immediately they in Seramis (see elsewhere).
I am still am considering whether I overnight the tuber in the Axoris... let?
What do you think? Has anyone experience this or a better idea?

Thank you ever

Michael

Hello

You can in there, did I already do most of the time I do it take leave a tuber put in freezer bags and spray with the spray there couple of times and let it be then 1-2 days.Always worked until now, helps very well against root lice.

Problem is only there to buy no more Axoris.

Hi MIchael,.

just not too loud to say you used thiamethoxam!;)
In your limited wisdom, the EU Commission decided the use of Neonicotinoids such as e.g. Axoris disallow Provado and co from 2014 to 2016 as test run whether for slows down the bee and/or can be stopped.

I have over the years for all my plants, yet the acaricide Acequinocyl used only appropriate Nicotinoide, at Spinnenmilden, and had so far no loss as a result. The former are also systemic poisons and linger or spread over weeks in the plant tissue, resulting in a certain long-term effect. Unfortunately know I just not how good a relative metabolic inactive, dormant since, colleagues a long time bath gets. In addition to the active ingredients, namely still surfactants contained which allow a better absorption and wetting of the leaf, but are certainly harmful in the long term. If you see no damage by the larvae so I would keep therefore first it rinsing your principle. So enough of the nerve agent on the tuber surface is likely already remain to prevent a new attack...


The input was helpful, hope

I'd advise against this-this is a really nasty group where that falls.
And that like the bulb if it is located in a water bath I can not exactly estimate - but I would think that I don't like her.

Where I also am not aware - whether it helps active ingredient against Trauermücke lavas – these Neonicotinoids help under normal circumstances against all lice and whiteflies. - and me, also against the Colorado potato beetle.

' You can fight Sciaridae relatively easily with a Bacillus thurengiensis preparation - do you look bio help - Vectobac - or what is cheaper if you get it somewhere - Biomück (which is the same).

Or what are also super Fridays - with nematodes (Steinernema feltiae) - get normally in the bio help - the help best - are but relatively short-lived — IE, you can store which itself only over a short period of time in the refrigerator

Ich hatte letztes Jahr auch ein paar befallene Knollen, aber weil es nur Sauromatum venosum waren, konnte ich damit schmerzfrei experimentieren. Da ich bei der Tissue Culture mein Pflanzengewebe mit Natriumhypochlorit Losüng sterilisiere, dachte ich mir, wenn das Gewebe das überlebt, die unerwünschten Gäste an der Oberfläche aber nicht, kann ich es damit versuchen. Ich habe die Knollen also ca 5 Minuten in einer 1-3s Lösung gebadet, danach gründflich mit klarem Wasser abgespült und auf Küchentüchern trocknen lassen.

Das Ergebnis, keine Ausfälle und alles was nicht auf die Knolle gehört war tot.

In der Facebook Gruppe berichtet Steve Jackson von Cairns Australia ähnliches:

Zitat

Sodium Hypochlorite dip
After the tuber is free of soil, mix
100ml of Sodium Hypochlorite (Usually this is available with 10% active
ingredient, if the concentration is higher than that youll have to
reduce the amount you mix into solution and vice versa) with 10 litres
of water. You can make a smaller amount if you have only one or two
tubers to treat of course! Totally immerse the tuber in the solution
for approximately 2 minutes. If there is an exposed shot on the tuber
try to avoid dipping it in the solution, but if this can't be helped,
just be sure to rinse it very well after dipping. This solution will
kill any exposed roots. Thoroughly wash the tuber in lots of fresh water
and allow to dry. The purpose of this treatment is to destroy any adult
worms and eggs on the exterior of the tuber.

Hello

Thank you for your quick responses.
I should have guessed on wash, too. Now I had the bulb for three hours in this solution, where more larvae have fallen off when I could adjusted me it after vigorous rinsing. Now it's sunk in Seramis. The mentioned remedy comes from surplus, because I often change the active ingredient to avoid any resistance.
Next year I will try the Bacillus thurengiensis and work also with predatory mites and bio help there meant that the probably rather not work in room culture. Comes on a trial still on. There's even "remainders" in case of emergency.

Love greetings
Michael

That going with the predatory mites also safe at room cultures – only such remedy may not use as above called.
But since you have to familiarise you something with the matter - Amblyseius cucumeris and swirskii can / should preventive again bring out (with the latter survive longer I also thriving stuff in the immediate vicinity did, because that also eats pollen). -These guys eat soft skin mite and the latter even yet also red spider, thrips and whitefly.

And Phytoseiulus can use only fighting against red spider.

Morning Michael,

because you had tuber damage by the larvae?
I find Sciaridae generally mostly rather 'annoying' considered harmful, since the adult animals literally floating one around the front and right on and below the Earth's surface nibble the larvae usually only mushrooms and their hyphae, and fine roots... noticed but never worse.

And if you should now switch to Seramis you could have ever more rest that indefinitely. Due to the porous nature, the larvae can move little to no on the granules and 'starve' in addition, the same is true for Nemathoden that can lead to total failure potentially Yes.

Although you might argue about the sense and nonsense of biological pest control, so I'm always a few yellow panels or - what with much better like - a few plant Drosera capensis stand between my plants. They look not only much better, as undistinguished but do work at least as well as the above tables and intercept the adult animals and prevent so another egg drop;)

well about the meaning of biological pest control itself there is nothing to argue - it's only the user whether the... wants to poison himself and his plants


the much higher cost--would be only what you could argue but I must say you are now don't care because she better dealing with the plants and the users a lot if you waive the chemistry - there are differences between day and night.

And the really large Benetzungen of cultures with Neonicotinoids block the EU really almost anything want because it kreucht what and fleucht kills me more positive than negative.

Dear Lord.Maso,
I hope your statements meant friendly, as I perceived them. As with most topics it is simple a black/white thinking to acquire, I personally differentiate something more like...

As I have already noted, nothing against a biological pest control is to say. Basically this is all eingenommen but ineffective. Especially in the room and house culture if a heavy infestation exists and you want to have a fast and best 100% solution.

The means used by Michael is a chemical derivative of the well-known nicotine, which is in fact highly toxic and different plant species is produced as a neuro-toxic Fraßgift. Due to its toxicity to be landed 40/50 years ago in periodically gardener with some serious symptoms in the Hospital since they met at the spray itself and ignores the protection measures. Over the years are therefore appropriate chemical structural changes were made, which reduced the affinity for Nicotinic Receptors in mammals, but untouched were the effect on arthropods.

Comments are therefore as "If you yourself want to poison" neither constructive nor technically correctly. When I think about my next bathroom cleaning I know also that the hydrochloric acid in the toilet cleaner is potentially unhealthy, as the Natriumhyochlorid in my disinfectant (especially if I mix both together and extremely effectively my lungs 'Sterilise') and I vaporize the corneal of my eyes by the sodium / potassium hydroxide pellets of my pipe cleaner within seconds and I go blind so would.
Chemical agents have their sense, therefore if you are informed and know how to handle them. The same also applies to biological and/or physical ("glue boards, etc.).

Therefore, the originally posted by Hauschka would fit:
"The mind is like a ticket. It does make any sense only, if it is used."

immer locker bleiben.....

Dear friends of tubers and pest haters... (I'm also both... :icon_winkgrin: )

only two small moderative notes...

1 would I plead "You" here for the friendly plant friends

and
2. when such topics controversial in public here on the tray, writes about no personal attacks please.

If such a discussion escalated, I will intervene moderativ... :icon_angel:


In addition, I think that both of you (Lord.Maso and bounty) you as a Amorphophile probably is closer than you think and your background
((ICH Lasse MAL Infos aus PN einfließen) - in a practical horticulture, with the other science education)
sure much mutual understanding... would develop in a conversation
Remember that written work always so final...

In this sense: Keep getting loose... ;)

... and: kill the beasts! By my side with biological or chemical agents (as long as they're legal...)

Happy killing, Bernhard.

P.S.: @ S.: the Lord.Maso is a freundlicher-- ;)
@ S and Lord.Maso: replace your stock lists times - there you will find what sure to Exchange:-D

I do not really offend itself the Mr S. - but offend he must me also not - especially if he should - go itself even before its doors because I should my mind also use...

Just because you are not really properly familiar with a topic can you not say but something is not working. Since I have for my person over 20 years of experience in dealing with chemical pesticides and for 3-4 years with beneficial insects successfully whitefly, thrips, spider mites, Trauermücke larvae and soft skin mite have the grip I can say quite, that it works. And Furthermore, I would argue that I rather think in shades of gray because I know my way fairly well with two variants.

In my experience there are always faults that cause the problems.

It's about 1 head, he sprays not the whole world.You should also always still distinguish between greenhouse and the 5 plants on the window sill.

So I am doing nothing. I check regularly, and if I see a few larvae, I remove it from the bulb. Then I replace the MOSS. I leave the used dry. Thus, the larvae die off.
Only the tuber in new Moss. That worked until now always good

As far as I know, the larvae eat only dead material. Since no major damage should cause one or two larvae on a healthy tuber.

I can join here only Ronny and even if I don't know Michael, I don't think that he fits to the chemical weapon, because he saw a single Trauermücke or their larva. Especially since I didn't realize is, if already the tuber itself is - has been attacked so my question to him. If the larvae are already (analogous to Nemotoden) in the tuber tissue systemic poisons are absolutely no alternative. Else I see that with regard to Sciaridae as Shreck.

Straight and because it apologized for titanum not to - the term - weed species is, I'm someone who one day sooner than later pests wants to get rid before the damage leads to the loss also.

The small conflict with Lord.Maso regards, comments such as 'nasty group' and the general negative portrayal of all matter including their annoy me due to my professional background / users. Hence my brief digression in the bathroom chemicals and their dangerousness. This the appropriate quote includes, to consider whether, as well and what to apply where... ;)

The latter was - as you can read above I - related in the context of the whole issue, and not a single person. Even I remember so much semantics :icon_seb_zunge:

Hello together,

really sorry that I have kicked off a debate so violent, I suppose but that here no harm meant. The posts were informative to me always, thanks again.
To get back to my tuber:
The bulb I treated yesterday immediately, since it with 144 g. I am going absolutely no risk or experiment that is my biggest A. titanum tuber Certainly I can not say that the larvae are harmful, usually, so in the earth they are just annoying in my experience, but there is also enough adult material in the Earth. (Tuber was stored in Sphagnum without substrate) were in the present case however extremely many larvae directly on the tuber; especially where the new roots to grow I could see them with the naked eye wandering. The presumption loves so close that the critters in the emergency use fresh material. = Fire on the roof! therefore fast acting used.
In principle, I'll try biological measures next season although bio help of predatory mites has discouraged me (RLF).
I use yellow boards constantly, but more as an indicator, to identify possible infestation.
For me, have beneficial as well as chemistry, all the individual cases depends on.

Love greetings

Michael

Hello
I had Trauermücke attack ever on tubers, however, a simple, cheap and environmentally friendly method, viz. water, helps even wash the infected tuber and most wars that for the mosquito larvae otherwise re-infestation again, wash the bulb. Otherwise the best Vorbäugen helps with yellow stickers, dennen stick mosquito bleiben(Leider manchmal auch Blätter der Pflanzen oder der Pfanzenhalter selbst :icon_lachtot: )

with beneficial against spider mites I have so far had no success, ordered 2 times already, predatory mites, have to say on the delivered dose I could find not only predatory mite
through regular wash have I that but also to a tolerable level re to adorn can

2 times I poured against Dick mouth Rachael Nemathoden, it is hard to say whether it has brought, I can see if is my Heucherabestand is not weiterveringert. This year it was extremely with the beetles, the larvae were found also in many pots which not only at my Heuchera sodas much is received, how many larvae in a small pot were was appalling. (often the 20 larvae at a very small pot)

Very beneficial use against scale insects would be interested, so there does anyone have experience? Aphids and spider mites can be to remove most often with water or at least reduce, or outside predators reduce itself usually the aphids.
But often so tenaciously keeping the scale insects on the leaves that even a strong jet of water hardly helps. The scale problem although not my Amorphophallus for some of my other plants. There, every now and again the chemical mace, use what I want to change of course because otherwise so far nothing helps.

The parasitic wasps of Metaphycus flavus and Metaphycus flavus should, however, help, which established times someone or are the native species, or at least types which survive nciht permanently with us? Who replaced used to combat pests Yes Asian ladybirds zunemend the native ladybirds and brings also some problems with sich(kommen indem Herbst in massenhaft in die Häuser, verderben den Wein beidem pressen der Früchte).

Policy discussions are themselves completely in order - as long as it remains on the issue of and various respected pleasantries and not necessarily longer than 2 to complete alternative as an insult quotes are used.

You may misunderstand me - I'm sure no 'green' - I was still must be when a chemical preparations to counter a coarser cut.
I want to also improve the world - BB´s is not about that well at all.

It is rather a question - if I mention other methods kinder to plants to work something - then be drawn in the following comment in the ridiculous and yet condescending treated (by about sense and nonsense of biological plant protection)-this is probably to understand if I swing with the sarcasm Club.

If then in addition, that someone feels offended if not completely scientifically correct statements are made on "not so good active ingredient group" - this statement, but the practice is true as beneficial hardest do if Neonicotinoids - or after the usage of such on the longest lasts until they can be reinstated
can't ever happen that a situation escalates.

And now to Seitis question:
Against scale insects I have not used yet beneficial. I would also have no experience reports or similar where read/heard.
I suppose that really works as at the beneficial insects against mealy bugs - the funktioniern only under the best conditions.
Is easy to use a paraffin oil preparation the most sensible in the case - this is Austriebsspritzmittel 7e, Paramaag relatively human - like summer or something. Overdose and do not use excessive sunlight - that clean wet bitches - repeat 3 - 4 times and then more should have no problems
