Powdery mildew - An easily exterminated parasite

Thanks, that sets my mind at ease a bit to hear. Definitely going to get a UV light to check em out with. For the last couple years I’ve had a lot of rain near harvest and bud rot. Was able to catch it early last year but the year prior was a near total loss and have always had morning dew. Put them in containers this year so I can get them out of the rain and started noticing these spots, gave me a bit of a scare.

Yah the bud rot can be a pain in the ass for sure. Don’t let rain fall on your plants! If you are making seeds, bud rot can be killed by sulfur as well. Never treat a bud you are going to smoke, though.

I’m still searching for a plant I can spray. I want to do the soak in different substances like sulfuric acid and hydrogen peroxide. Probably should take the needle tip off my hypodermic though, because I’ve sprayed enough shit on my microscope stage! If you aren’t super careful with the sulfur water, it shoots all over the place, and then I have to clean that shit up. As it happened, the sphere of sulfur water on the leaf of the pea plant evaporated, leaving a large cake of sulfur behind in a tiny round pile.
After I harvest the currants I’ll go see the neighbors. The mildew on their farm must be ripping by now! And after a talk with the guy doing the farming… well, he’s feasting on some old wives tales. Ouch! Told me coarse and woody debris from the forest would help his ph on the blueberries he just planted. Poor fool! Sounds like me, a decade ago!

ok so…like… That’s mildew, any questions? :wink: A mycelium network that’s hard to spot, becomes the only thing you can see under UV light.

Only one of these images contains mildew, and it’s that out of focus pea leaf. They are sweet peas! All other images look like mildew but don’t under magnification. Also, They don’t grow and spread, either. The mildew on the peas does!

I would like to note that the mildew outbreak on the peas became visible when the infestation is clearly everywhere. Not only that, it was the hottest and driest part of the summer months, a literal heat wave! The mildew started popping off those little pods like mad. Some of the pods haven’t even formed yet, but the thickest batch has some pseudo chains of acospores. Yum! One day I’ll have to document the prime conditions for the production of the acospores. Wikipedia is hilariously feasting on garbage info as well. “citation needed” motherfuckers.

Great information. I really enjoy your approach to research and will continue to do so.

At one point I was bemused by the misinformation about mildew like it was some mythical creature of legend.
Nobody has to burn their house down to get rid of it heh heh. You just have to get inside it’s mind. It lives a simple life and is easy to kill. “Some guy” aka me, with a shoestring budget can blow away 20 years of misinformation in… lol! 5 years. Guess that’s why nobody bothered, it takes a while.

Bad ass pics JC,… Thanks for sharing the info

Here’s the nugget I really want to dig up. My question is this:
Once the acospore hits the incompatible plant species, what happens? Does it hatch and die, or… does it not hatch at all and release the spores?
Ohhh if it doesn’t hatch, that means there is some kind of plant signal it’s using to tell it when it’s on a compatible species. If it hatches and dies, that means it’s some kind of physical trigger, as opposed to specific to the plant itself. The answers you can dig out of the living parasite are amazing!

Another patch of shit that’s not mildew. I’m not sure what it is, though, but my suspect is some kind of disintegrating material swatch like a curtain.

ooo I think I spotted some mildew on yellow avens! I am going to test it and see if it’s hydrophobic! Potentially exciting hehheh :wink: I’ll post the results here in a little bit. IF it checks out, the next phase is documenting the sulfur water attack! yay!

ohhh yah, nice and infested! I think I know how to break the hydrophobic coating though. I got this idea from looking around outside! It’s got to do with surface tension. lol! Let’s see if I can make it work.

wow, that’s going to be a nutty video! I think you can literally SEE the acospores dying. Here’s how I broke the surface tension for a hydrophobic plant. First, I literally coated it in water, so there was an envelope of water on the leaf, covering every surface. Then, I dropped some sulfur water on there, which quickly dispersed over the leaf itself.

Interesting, Joe. Howdja get the water to spread smoothly on the leaf?

I had noticed even the hydrophobic plants got wet after a good rain storm, so I tried personally coating the leaf with water and it works! Dilutes the sulfur solution though, so I’m not sure how good an idea it really is.

very interesting! Not as violent as just putting the sulfur water on there, but it does seem to disintegrate and carry things away. I recorded over an hour of time lapse! If I were recommending a sulfur treatment on the hydrophobic plants, I would do this:
spray the plants with water first, and then wash the water off with a sulfur water bath. Once the water forms a film over the hydrophobic plant leaf, sulfur water stops bouncing off. Really interesting! I wonder if the leaf is still hydrophobic once it’s died and dried?

ok, it’ll take a while for skewtube to generate the 4K version.

Enjoy! Sorry it’s out of focus some times, I was busy with a hash ripping situation :wink:

We must have different leaves? Water/rain beads and runs off ours, unless I use something for a surfactant. Used to use something mild like Dr. Bronner’s, but have lately gone with an AG spreader/sticker. Detergent soaps can eat thru the waxy cuticle, I’ve read.
