Powdery mildew - An easily exterminated parasite


This is the mildew colony on the snow berries. I’m not seeing the pods, but I do see those clusters. Almost seems like the dark clusters explode at a certain time. Probably releasing the parasite within. This resembles the aster mildew and the comfrey mildew. I would need a couple days to determine if it’s one or the other, or a different colony altogether. My brain says it’s not the same as the aster mildew, due to it’s distribution on the landscape.

OMG!!! On hash church there is now this guy… archive seeds. He knows the story about powdery mildew. Amazing information I love it!

Damn! He was soooooo close to parroting back the information I’ve posted here. They cut him off after he was like you can eliminate powdery mildew from your garden. He never went into details, but what he did say, proves Bugbee wrong, of course, lol!

“Most people in North America had never SEEN powdery mildew until they received clones from somewhere.”

His story is the real one, it’s fucking nuts. See how it aligns with everyone who gets infested? Not like Collin’s “morning dew” story, Phew. That last panel was sketchy. This dude is someone who talks like a person who actually got infested and kicked it to the curb.

I think I love him. lol! He talks about breaking the life cycle to get rid of it. I could listen to him yak all day long!

It makes me wonder now, if the conversations I have with bubbleman actually does have some kind of effect. While I was prattling on he told me I wasn’t wasting his time. I was definitely super bummed out the panel was basically just quoting shit that was wrong. This time I just shot him a message saying the guy on the panel really knew what was up with mildew. Told him that was definitely “the guy”. lol! Now? This is where I party hard. Finally, some dude just came out and said the same things I’ve been saying all along. bah hah can you tell I’m excited? I should start making ice for a hash batch! Woo wooo!!! :train2:

I can still see some viable aster seeds amongst the mold and rot! Man 6 weeks stratification is taking foooorrrrever! I want my mildew colony now, dammit! hah hah they were talking about the dangers of studying mildew, because you need an active infestation. Which could then hit your crops. Instead, I’ve selected the host and colony that specifically CAN’T cause infestation. Due to the fact, I’ve only ever seen it grow on asters and nothing else.

So does this show that pm can winter over?

Oh it’ll show that and more! Once I get the mildew colony going, I’ll see how far it can spread. Studying it in it’s natural habitat is getting boring I can’t poke and prod at it during the winter while it’s dormant. Something does seem to happen to the colony when it gets frozen. I’ll be able to observe that process. I want to see how much I can learn about the seasonal changes the colony undergoes. Like… what triggers the replication event? We’ll see what I can tease out of the parasite. There’s a radical test I’ve got in mind. That could only come from the brain of a madman. Like… can I trigger it’s germination on another plant with proximity?

You could probably eradicate the mildew growing on the roses. I’m not sure about the trees, might be hard to get them covered with sulfur. You’ll need industrial equipment.

See, this is what got me thinking. The mildew on the thistles looks like the mildew on the comfrey. They are in really close proximity. So… does the mildew from the comfrey grow on thistles? OR is it just so close in proximity that the mildew is trying to infest.

Some powdery mildew fungi have broad host ranges whereas others are fairly host-specific . For example, the powdery mildew fungus that infects lilac is not capable of infecting cosmos and vice versa. However, the powdery mildew fungus that infects oak can also infect rhododendron and dogwood.

Thats why you woIuld need to identify the genus of mildew your plant has, on top of that you need to look at the variations within the genus, for which plants can develop vertical/horizontal resistance through breeding.

I waited for this time to really see if the sulphur had staying power sice the reinfestation (some) and the recent rains we’ve had.
I can confidentiality say there is a ton less now than there would be normally. The plants that had some reinfestation earlier from the untreated surroundings have not taken off with pm like they normally could have. Different strains handle pm differently of course but it’s not hard to see there is a big difference.
Much obliged @JoeCrowe

Yet no canna stores in my area carry it. They had some plants in there the last time i was in and they had sulfur residue all over but they wont sell it cause its $4.

I went to Canadian tire and they had sulfur powder in a canister for 15$. I can’t get it at the hardware store, but they do sell it at the grow store here as well. They also sell sulfur pellets 99% in a bucket you can use for soil acidification or powdery mildew extermination.

I’ve been using Sulfur happily for 2 years, thanks to you Joe. I was a sceptic at first.

Thanks! I consider you to be a beautiful human being who earned my respect by embracing change. Hopefully that’s not too cheesy :slight_smile:
