Best organic fungicide available in Canada?

Hi everyone,

Im hoping someone can point me in the right direction to source a good fungicide in Canada that is safe to use during flowering. I noticed the beginnings of powdery mildew on this Durban Poison since the nighttime temp has been dropping over the last few days. I have been researching and scouring the internet to try and get a head of it but am not having much luck. Obviously not much I can do as far as the environment goes and it seems like all of the better options as far as fungicides that are safe during flowering aren’t available in Canada. There is a Canadian distributor for Regalia but as far as I can tell they only sell to commercial growers, I will call tomorrow to confirm but I would likely have to buy a case of it if they will even sell it to me which probably isn’t in the budget right now. I can get southern AG shipped here via Ebay but it wouldn’t arrive in time. I used a foliar h2o2 dilution today and pruned off what I could to try and slow the spread but the weather is only going to get colder and wetter from here so I don’t think that’s gonna cut it for long. Any ideas? I’ve tried a baking soda solution in the past with limited success but it neutralized a lot of the terps and I’d like to find something more systemic if possible... please help!

Make a solution of 2 teaspoons organic apple cider vinegar per quart of water. Spray on the plants to eliminate and/or prevent mildew growth.
Add ½ teaspoon baking soda per quart of water. Spray.
Oil sprays consisting of neem oil, sesame oil or fish oil work on powdery mildew as it does on many fungal diseases.
Milk sprays have been very effective in eliminating powdery mildew. Combine 40% milk with 60% water. The milk’s protein acts with the sun to create a natural antiseptic, killing mildew as the result. Milk sprays should be applied in bright light every ten days as a preventative measure. This method can be employed to resist mildew on any garden plant.

oops, the neem may not be ok during flowering. wait for someone with knollage of useing neem oil

I have used it in the past but only in veg, it’s pretty smelly...

Green cure kills on contact potassium bicarbonate

Get a silicon product to Goliath spray it will raise the leafs ph and make it so it won’t grow. When u saw the ph mine was at which was 11 I instantly knew it would work great for outdoors plants. I’m not sure though since their are buds so imma ping someone because I would love to know if I can spray while in flower most likely not. @Renfro

You can give them a light spray in flower using potassium silicate.

Tornado I'm from Canada too. I wanted some Dr Zymes Eliminator which is only sold in the US, so I had it shipped to a drop ship site and they're shipping it to me.

Thanks everyone. I ended up grabbing something locally because I didn’t want to wait for anything to ship to start dealing with it but I appreciate the suggestions. Hopefully I can keep it at bay until harvest.

@Hobbes thanks for the tip, definitely gonna setup an account for future use
