Beating budrot... tactics and prioritising temp or RH?

[Budrottenjonny]

For anyone following this, a quick update. I decided to decapitate her below the initial infection site.

I ditched any bud that was directly around it but trimmed and saved what I could. Keeping a careful eye on what I'm drying - I can see what looks like very small areas of wispy white growth where the stalk of the bud is cut but I figure this is part of the normal drying process and so far no further spread.

The plant itself seems to be fine but I'll keep a careful watch to see any further signs of BR. I don't know how the stress of cutting her in half will affect onward growth but it's a learning process, eh?

One thing weird thing tho... wonder if anyone's seen this before...

I just noticed that one, fairly young leaf tip had got some kind of white mold on it - right near the top, near the cut site on the main stalk, which developed a tiny bit of white mold (I think - only visible at 30x). It didn't look like bud rot at all, and was isolated to just one leaf and the very tip. I pulled it off carefully and a couple nearby and I'll keep careful watch.

make sure to clean any type of tools you used afterwards so you dont infect other plants and keep the cycle going. I make it a habit now to have a pair of scissors for each room and veg.

Thanks @cemchris - yeah, I forgot to clean the snips after the initial chop and it was not a pretty site under the magnifying glass when I looked a couple of days later!

I'm cleaning everything with Dettol now, which I think should do the trick. (https://en.wikipedia.org/wiki/Detto...gredient in Dettol,castor oil, soap and water.)

All sounds like stuff I wouldn't smoke. ☹

I hear you, thanks for pointing that out.

I've been cleaning the snips with it then wiping them with tissue - do think that even then, doing a wet trim would leave traces that would render the harvest unusable, in your opinion?

What if I ran them under water after cleaning?

And if not, what do I need to get hold of?

I read Isopropyl alcohol but surely that's not great to consume!

Iso would totally evaporate leaving only water within minutes. But it might hurt the plant. I've also heard hydrogen peroxide 3 to 1 with water.

Personally I would and have just tossed the out and start again.
I literally just did this a couple months ago ☹ I was 3 weeks from harvest. Tossed them out like bad news.

I am very picky about what I smoke, if i see any mold of any kind, i toss them clean everything with bleach and start again.

If you have mold, you're not going to get rid of it all. You're basically choosing to smoke it if you keep it.

Just my opinion though, many people have smoke their mold, but not me.

just do like the medical/recreational side does and dunk in h2o2 solution to rid you of the mold. /s

Botrytis starts and travels inside the plant. A topical wash isnt going to remove it.
Keeping humidity below 50 at grow room temps helps, Dialing back watering the last 2-3 weeks helps, burning sulphur up until flowers are forming helps, not touching buds helps, keeping light and dark cycle temps close helps, not pulling leaves near bud sites helps, and lastly filtering the growroom air with a hepa filter helps. You can also buy UV air purifiers that recirculate air through a UV sterilization lamp, those help. Added UVC to the room would help dramatically...

Only things I do for prevention is run my dehu on constant run the last few weeks which keeps humidity as low as 35%, I burn sulphur up to week 2 of flower, and I ease way back on watering when the buds start to swell.

sorry it was '/s' for sarcasm. You watch some of the videos and you are like "just throw it away". instead they dunk the whole plant and trim around the rot.... Sorry wasnt be serious in the slightest. i dont mess with mold.

i will use treatments to prevent and treat mold. But if it hits a certain point its just gone. Anything after that is just experimenting with recovery for myself.

Lol I should have picked up on that when you mentioned the medical/recreational side

im not afraid to use chemicals in the slightest. fungicide included. because i have seen almost all of them that can be legally used in food. Be used. Not saying i like it. But lots of them especially the OMRI listed category. Are not terrible and can do some really serious stuff even when compared to some synthetic nasty stuff. Problem is agro put more weight in big chem and pharma than they did the health medical side until this last big swing in health and quality we have today. I have met farmers that still want to spray the deadliest banned substances cause they think its just better. But they only equate it from a profit standpoint not human standpoint. Human factor has slowly become the more important factor. In some cases we saw it go away and come back full swing.

So to that. I will use treatments that will metabolize if i can use them within the time frame. Regalia i can spray up until harvest and is organic. havent tried it. But if i have to i will let others know how it works. has not worked on my pythium problem. but it is apparent that area is suffering from pythium blight as the test results came back positive for it. So i will attempt banrot as it goes into flower. Mostly for the damp off effect it provides at stopping further rot of the roots. not rated for food or marketed for cannabis. But i know it works. I do plan to send out some samples after the grow is done and see if any of the chemicals i used show up in any samples of the bud itself. Mostly to experiment with how they metabolize for my own knowledge.


edit: summary im not afraid to go systemic with some products available.

Cheers man, I understand why you'd do that. I'm now thinking about doing the same.

I've not seen any further signs of BR but you're saying that doesn't mean spores aren't sitting inside or on the buds...

I have just noticed *one*, tiny bit of white 'fuzz' form only on the edge of a leaf were it was cut back but it's only visible under a loupe and looks nothing like BR.

I figured there are a LOT of other mold spores kicking around this space - it's part of an old house in one of the dampest areas I've lived in. I was planning to bin that particular bud anyway and I've seen no evidence of mold elsewhere, even though there is other damage to other foliage.

For context, I'm new to this, growing only one plant and I can't go again until next Spring. I have to weigh up the risks and everyone's view on that is going to be different, depending on all sorts of factors. At the end of the day, I don't fancy inhaling mold spores though...

I realise that we consume mold all the time (if I threw out my tomatoes every time one of them got blight or BR, I'd never have a crop) and that we will all have smoked some naaaaasty things along the way - the difference is what you choose to do once you're aware, I guess.
