Inquiring minds need to know.
Can someone give me a brand name for a "good systemic fungicide" for my container hosta?
The term was in the thread by EstherB about ebay stage 4 liners offered for sale.
can someone give me a need for such ...????
what fungus lives INSIDE hosta????
we shouldnt really encourage.. willy nilly use of chems ... until we are sure you have a need for them ...
and if you tell me the media... then why do you need it in the system of the hosta???
i am so confused ..
ps: really now.. gleaning brilliant ideas from an ebay seller??????
I was just going by the material quoted in an eBay listing, quoted by .... EstherB I think it was. Let me get the link to that thread.
In this information where they were selling stage 4 starter plugs of hosta, they recommended a good systemic fungicide to keep the little TCs clear of fungi.
It sounded to me like there was such a chemical product available, and I wanted to be informed. Not considering applying chemicals helter skelter here, since I believe in keeping my wild bird and natural predator population healthy.
What could such a systemic fungicide be, that's what I wish to know. And you are right, Ken, what was I thinking, but sometimes I discover that I (moi) am the one living in an alternate reality, there is a whole different world out there...with folks living in it.
I need a good fungicide in order to grow roses here. Hybrid Tea roses cannot survive in this area without some form of Black Spot control. In fact, I have removed most of my "HT's" simply because of the amount of spraying involved.
Many of those posting to the Rose Forum believe that Bayer Advanced Disease Control For Roses, Flowers and Shrubs is the most effective product available. I reluctantly use it with success.
The one to use is Physan 20. Several of us hybridizers are currently using it while germinating our hosta seeds. I'm not sure if it is a "systemic fungicide", but it is a fungicide (and other disease control, etc.) which is suitable for use on seeds, young seedlings, and a wide range of other applications. You can buy it on ebay...and one bottle goes a long ways.
It seems to me to be unwise to treat for a problem that you haven't experienced. That's what Integrated Pest Management (IPM) is. First you identify a problem, then you identify the least toxic method of solving it. That would be my advice.
i too used to collect roses .. and all the chem use is one of the reasons why i quit ... didnt need to being do all that with babes in the yard ... [i mean children.. not your hosta.. lol]
i can see the need for such.. with seedlings.. damp off.. etc ... and babe TC are no different than seedlings ... by that stage ... especially in a greenhouse situation ... its so totally different than outdoors ...
but i see no need in large pots with fully mature hosta ...
it comes down.. as usual .. health risks aside... i dont think its worth the money/cost ... no one has claimed any benefit .. for what i think moc wants to use it for ...
I read Bayer Advanced Disease Control fights crown rot. I had that last year on a very large h.'Blue Umbrellas' and it worked to stop rot. I plan to spray the grounds around plants with that several times this year.
For growing seedlings from seeds I use Captan. I put a little Captan into water in the tray, and the medium in seedling cups transports it together with fertilizer via capillary action up to the surface of the cup. I have no molds in those cups. When the ground around plants is drenched with a fungicide, then the fungicide hopefully protects the plant.
I just read again The Hosta Journal 2013 Volume 44 Number 1. There on page 18, Warren J. Pollock of Pa writes about using an 'all-purpose systemic fungicide such as Cleary 3336' when using topsoil as part of a potting mix for planting hostas in containers.
Here is a link that might be useful: Systemic fungicide Cleary 3336
Duly noted, Babka.
However, I do not use topsoil as part of my potting mix. How effective would it be when NOT using topsoil, I wonder.
When all your parts of the mix are sterile you probably do not need a fungicide so much, but spores can blow in, come from insects and rain, or arrive after you touching other plants.
