Milk to treat powdery mildew

[zem]

I was surprised as to how well this worked for me, I had two plants that had spots of powdery mildew on their leaves in the early stages of infection and they were about 20 days into flowering. I researched about what I can use at this stage to fight powdery milder. I used milk, and it really froze the infection dead in its place. The biggest downside to me is that the smell of milk lingers for another week but it is completely dry and did not seem to attract insects. I also gave them a heavy shower about 1 liter for 2 plants so I can still see the milk residues now 2 weeks after application, but the smell is completely gone. Anyway, I am pleased as to how well it worked against the infection and it is after all a natural product that I am more comfortable fumigating flowering plants with it. I would definitely not want to use it 20 days before harvest, because I want to avoid even milk residues in my buds. Anyone ever heard of or tried this remedy? If so, how well did it work with your plants?

I have used it years ago on roses outside and yes, it did work. I haven't had much of a problem with PM on pot. But if i do, i am going to remember your post zem. Thank you for posting.

Yeah I used it once on my stuff. I had a pretty significant attack and didn't have anything but milk to use and it worked quite well where I could spray it on the mildewed spots.

You need to get a blacklite and take a close look at the plants with it as PM that is still invisible to the eye will glow under blacklite.

The milk really treated the mildew. I only did one application and its residues clearly remain on the leaves and I noticed the mildew trying to take hold then failing with no further intervention from me. the end product did not have any milk taste or smell whatsoever. I did a regular bud wash with water.

YEs i used it outdoors. I am not using it anymore because i am using a silica additive that is working great. If i have a problem i usually wash it down with monopotassium phosphate mpk but this happens only when i dont have ample bioavailable silica in my medium. However i had very good results with milk. I guess i am not using it because of the smell that lingers for a few days and the glazing and residue that it leaves behind. Mpk is organic and can be used on buds safely and feeds the plant foliar and it works in slowing it down. i think milk has a stronger effect though. I tried lactic acid and it failed badly. So it is not that why milk is working i guess it is the glazing effect that prevents spores from formong but i am not sure. Good luck.
