Regalia review

Someone on these boards suggested Regalia for PM. I figured I'd give it a try. My plants are about 3 feet tall in veg, 36 plates total, 6 of them had some light PM spots. I applied Regalia per instructions and waited a week. The plants that had PM on them had further progression of PM and many of the other plants that didnt have PM are showing signs of PM.
Long story short: dont waste your money.

Dilute potassium silicate always worked for me and is dirt cheap.

I'm sure your experience will save somebody else some disappointment so thanks for sharing.

:peace:

Myself and a few other suggest Regalia for "controlling and preventing pm". It not a one and done cure all. Few products are and most are unsafe.
But it IS an excellent preventative used by AG pros and in grow-ops that are subjected to intensive testing.

Long story short - if you had 6 plants out of 36 with PM you're room was already severely infected. You might be able to limp plants to the finish line, but you're not going to eradicate PM once more than 10% of your room is infected.

Sorry it didn't work for you but PM requires a multi system approach. There are no one and done safe "cures".

Exactly, you have to keep spraying every third day and use 2oz/gallon. All I can say is it got me through to harvest so I could tear the room apart and disinfect everything.

Has anyone used potassium silicate as a preventative/help with for pm? @OldMedUser does, trying to get ratio of mix.
Any help appreciated.

I foliar with Si. I guess I would call it a preventative. It does strengthen the plants. I started using Power Si (similar to Aptus Facilitator) at 16ppm/gal.
Si is a great way to control stretch too but you've gotta keep the ppms low with Si or it'll negatively affect yields. If using potassium silicate, it you have to calculate for the extra K

As a PM preventative, the idea is cellular health/high brix and you want the tissue inhospitable so the taproot cant "bite in" and take hold because PM will form invisible networks before spores are visible to the naked eye. There's a few different ways to go about it. Some alternate Si with EWC teas. The teas provide competing bacteria. Some people use Aloe and Silica and have stunning results.

@OldMedUser ...what are your ratios if I may ask? I live in NS Canada...very humid here in the spring, summer. PM can be tiring..

I used 1ml/L of Rhino Skin but have some plain stuff that is a lot more concentrated so would only use half that. Very dry here so PM isn't much of a bother indoors but don't grow outside so not sure if it would be out there. Planning on planting a bunch of autos out there early June to see if they get finished before frost hits as regulars never do this far north in Alberta.

You basically want to alter the pH of the leaf surface so it can't grow. Seemed to kill off the existing stuff too. Acidic formulations are supposed to work as well. At least with the potassium silicate it's something the plants can use and makes them tougher against PM and other problems too.

:peace:

Armor Si by GH is a good product with silica & potassium, and i also used potassium bicarbonate, as well as hydrogen peroxide, and all 3 of these can be used in flower. I was spraying daily with something for several weeks. They just got me through flower and i'm harvesting this week with "almost" no signs of pm...However my younger plants in veg went in the trash :wall:

And make sure to ONLY spray when lights are out, or you'll burn your plants badly. :fire:

GH Exide is another good product but only in veg...It turned my pistols brown early by using in early flower.

Exactly, I'm in the Mojave Desert and it's rare my RH gets over 10%. That's why I was so shocked I got PM, worse I couldn't get rid of it with the less expensive remedies. I bred the genetics and got seeds. It has a lot of SSH in it's line so I wanted it. Now I worry it's genetically predisposed. So that means a lot more stabilization that I probably won't live long enough to do. First world problems :lol:

Yeah Regalia isn't something you are going to see immediate results from if you have a pm outbreak, but it will help. I am starting to use it on my new seedlings soon, and we shall see how it does as a maintenance treatment. I just gave them their first taste of Armor Si...I believe the Regalia site said to wait til there are 4-6 sets of leaves before using on young plants...

Do you have experience with using Eagle 20? Thank you for risking your wallet for us.

I've used regalia, procidic2, horsetail tea, potassium bicarbonate, isopropyl and micronized sulphur to treat powdery mildew. Hands down the sulphur has worked the best for me. Everything else will slow it down for a couple days and it just starts right back up again. The sulphur kills it AND keeps it from coming back for weeks or in my case for months. I was dealing with pm for about 18 months before I sprayed with sulphur, literally nothing I listed above worked. It's been about 4 months now since I sprayed with sulphur and I can't find a speck of mildew on my plants.
