Giant Knotweed Plant to induce resistance. . . Milsana, Regalia, supplements. . .

[hasshoes]

I've been reading up on this as something to help fight grey mold which is really taking down my plants (humidity+wind+rain+florida weave= epic fail! ) . . . .

I think Milsana (a derivative of it. . . maybe not organic. . . but in future could be?) has been mainly used in Germany. . . Ami. . . have you tried it?

Also looking at Regalia. . . though it's way too expensive at it's current price/size. . . I was wondering if I could just go to a vitamin store and make my own giant knotweed spray.

In one study it did better than Serenade when combined with other stuff on early blight (though I don't know how impartial the study was?)

Milsana (which may not be available here?) several years it didn't test well on grey mould but another year it did

Of course I know all about aspirin etc etc. . . just found this and wondering if it could be better.

Thanks Ami (or anyone else) . . .. . . if you've heard of it I appreciate your input.

I read the online label this morning and I guess it's not available for home use.

If I see any knotweed extract at whole foods I'm going to get some. . . I figure if I try it on a small plant it can't really hurt at this point.

That's great top see a positive use for knotweed! I hope you figure out a home brew mixture that works.

Seems like you could make your own extract with a bunch
of knotweed and a bottle of cheap vodka (I like using 80-proof
vodka for this, because it absorbs both water-soluble and
alcohol-soluble compounds in the plant material).

Knotweed is an invasive weed lots of places, and ecosystem
management administrators would be only too happy for
people with some use for it to chop some down and haul
it off:

I remember seeing it around local wetlands, the edges of
creeks, lakes, and ponds, and so on, although I did not know
what it was or that it was an invasive, non-native weed.

I found Milsana at the site below. As you said it works the same way as Aspirin does in turning on the plants defense mechanisms. The organic product I found over here that is sold for Gray Mold (Grauschimmel=German translation) is a product I use for my fruit trees made by NEUDORFF called Neudo-Vital Obst Pilzschutz. I have not used it on my tomatoes but according to the instructions it can be used on vegetables. Here's the links. Ami

Your giant knotweed is the same as Japanese Knotweed, which causes a lot of problems in Britain as well. We're close to importing a psyllid which feeds on it as a biological control. I've seen various estimates for the cost of eliminating it by chemical means, from £1.5 billion upwards.
