Verticillium.. Please, someone with experience or good info
    #19777811 - 04/01/14 11:07 AM (9 years, 10 months ago)

I've looked everywhere and still do not have a clear understanding of Verticillium.  :confused: There seems to be a lack of clear responses and its hard to gain a full understanding of it so if anyone can share some info or resources I would greatly appreciate it.

So I have a couple questions that hopefully some of you can answer or shed some light on the subject.  :sun:


1) I know Verticillium loves high RH and low FAE. So if you increase FAE & lower RH to (85% ?) can you beat it or should the whole project just be tossed right away?

2) How does it spread. Its a fungus right, so when does it reach the stage when It can spread and how dangerous is Verticillum in terms of spreading and effecting other projects?


3) I know it will deform caps and stems, can cause mutant blob looking growth if effected very early and grow greyish/whitish almost like mycelium on caps and whatnot, but can Verticillium cause a fruit to be spongy feeling and already blue on the inside immediatly (rather than turning blue) upon cutting open?


Thanks everyone :thanx:

found this but its talikng about plants Verticillium wilt is caused by the fungi Verticillium albo-atrum and V. dahliae. These fungi attack a wide range of plant species, including cultivated crops and weeds. They are soilborne in field and greenhouse soils where they can persist for many years. V. albo-atrum is a cool weather organism that grows best when soil temperatures are between 65 and 75 degrees F. V. dahliae is more active between 75 and 83 degrees F. Although disease is retarded by the higher temperatures that favor Fusarium wilt, visible symptoms may appear to be more severe when high temperatures exist, due to restricted water movement in the plant brought about by damage done to the water conducting vessels earlier in the growing season.

Management

Because Fusarium and Verticillium fungi are widespread and persist several years in soil, a long crop rotation (4 to 6 years) is necessary to reduce populations of these fungi. Avoid using any solanaceous crop (potato, tomato, pepper, eggplant) in the rotation, and if Verticillium wilt is a problem, also avoid the use of strawberries and raspberries, which are highly susceptible. Rotate with cereals and grasses wherever possible.
Keep rotational crops weed-free (there are many weeds hosts of Verticillium).
Whenever practical, remove and destroy infested plant material after harvest.
Maintain a high level of plant vigor with appropriate fertilization and irrigation, but do not over-irrigate, especially early in the season.
Plant disease resistant tomato varieties, labeled V (for Verticillium) and F (for Fusarium). These disease resistance designations are usually shown in seed catalogues. Fusarium- or Verticillium-resistant varieties of eggplant, potato, and pepper are generally not available.
If soils are severely infested, production of solanaceous crops may not be possible unless soil fumigation is an option. See the Ohio Vegetable Production Guide (OSU Extension Bulletin No. 672) for information on soil fumigation.

Thanks for that info.  Im still confused on a few details about Verticillium though.

Mainly how easily and at what point does it spread and how important it is to control it?

Also if it can make fruits soggy feeling and already blue on the middle....



Someone has to have the answers :confused:

The link that Happy posted stated that it's rare for the vert to be spread by air. However, it can be spread via water so you definitely would not want to dunk something like that. Do you have any pics we could take a look out to better help you with what's going on? If your mush was soggy & mushy immediately upon being picked I would trash them. It is not uncommon for a mush to be bruised blue inside and out even before handling it.

Verticillium is spread mainly by direct transfer by bugs or people to the casing layer i.e. you touch something contaminated with it like dirt and then touch your substrate. Misting a contaminated substrate can spread the spores to nearby substrates as well.

If you're growing Cubes though or another species that doesn't use a casing layer it's probably not verticillium. It sounds more like your mushrooms are getting waterlogged, like from misting at times when it's not necessary.

They were not misted at all. the caps just start looking deflated and the whole fruitbody has a soggy feel to it and as I said is blue immediatly upon cutting.  You dont think the problem is Verticillium?  I dont know how they could be waterlogged, what else could it be?

Can anyone chime in with some info or answers to my original 3 questions about Verticillium... or at lease it seems like Verticillium to me....could be wrong.  :stars:

You dont think its Verticillium? I put peroxide on the fruits and they started to fizz up pretty good, would just waterlogged fruits fizz too?  I cant figure this one out man.

Thanks

vert sucks man.  i had it rip thru 4 bulks of mine in a month.  u are correct in wanting to up FAE, DO NOT MIST, and also really important and was helpful to me was dropping temps, like down to 67-68.  i was getting them on cased and uncased substrates of cubensis.

isolate any project that is badly infected with vert away from others, IMO.  mine spread tub to bucket, etc fast, but i was also misting them all a lot, b/c it doesn't really show until pins are 1" or so.  misting it before it shows, spreads the spores around, especially if ur projects are close together, like mine were.  if its not a bad infection i don't think u should worry about tossing it right away, mine still fruited, just didn't look that healthy.

Verticillium is a fungus and while FAE will reduce the problem it is easily spread on insects and by touching
Verticillium does not cause spongy caps and blue in the mushroom.

look up references for "dry bubble"

Peroxide can fizz on pretty much any live fungus including mushrooms/mushroom mycelium. It's also normal for there to be some grey to white mycelium on caps of small pins. It actually remnants of the universal veil which covers a primordium before it becomes a pin.
