Any Updates?
Howdy,
I've had test that verify that i'm dealing with fusarium.
I haven't beat it but, I have been able to suppress it.
I have found the following fungicides effective in slowing it down-
-Heritage
-Mancozeb (leaves increase in size)
-Subdue Maxx
-Daconil (doesn't do a lot, but it does help)
It's inspiration for us organic-heads who keep saying that we must *harness* the microbes instead of fighting them. Embrace dirt!i'll give an update: i gave up. i scrapped my whole hydro system and switched to soil.
i tried everything mentioned in this thread (with the exception of aliette -- i don't think i ever tried that) and the fusarium came back time and time again. the last lab test i had actually showed pythium too in addition to the fusarium.
i switched to soil 6 months ago and the problem disappeared overnight. of course soil brings a whole wealth of new problems (like watering, ugh!!) but no more pythium or fusarium. actually i can't say for sure that they are gone as i haven't had tests done since switching, but if they are still present they are entirely asymptomatic. the plants look great right up until harvest!
i wish i had a more inspiring update but maybe this will be helpful for the folks that don't mind sacrificing the convenience of hydro.

It is, however, by being in dirt we can encourage other microbes to develop, thus creating, hopefully, an environment where the balance goes in favor of the good guys. Because in a sterile environment once *any* microbe gets a foothold and it's all by itself, it's going to take over.
How did this come to be? Could it have been due to misuse and/or overuse of fungicides? What about monocropping, could that have anything to do with the resurgence of new strains of Fusarium? I don't know! But it's something to consider as we grow our heirloom foodstuffs.Additionally, new races of both pathogens have been identified that are capable of overcoming the resistance in many popular tomato varieties.
can high heat sterilize a soiless medium infected with these problems sailfishdan? I.e 250°f
great links btw, thanks for sharing
This fungi is only in hydro systems?
