This is the only treatment you need against powdery mildew on #squash plants (or any other plant). Squash plants are very prone to leaf diseases especially #powderymildew . This fungus thrives on the surface of wet leaves and proliferates in my hot/humid #Florida garden. Spray with 1 cup of hydrogen peroxide per gallon of water to clean and disinfect the leaves.

You rock Jerra thank you
I have been looking for solutions for my pumpkin they have powdery mildew. Thank you will try this.
Thank you for this! I thought mine had powdery mildew but I see that the silvery color is natural. I have tried using diluted milk on the leaves.
What time of day should I apply the concoction? I burned my leaves doing a baking soda and soap and distilled water because I was told to apply it in the morning. I had to hurry up and rinse the leaves. Caught it before more damage than what happened occurred
Spray with peroxide and milk
Thank you Jerra
What time of day should this be applied?
I also mix a tea spoon of baking soda a couple drops of dish soap and a couple drops of vegetable oil spray every 3 day or as needed
Ha, yeah, my “squash” leaves 😉🍁
Thank you so much. I reside in Deltona, FL and can relate to the pest problem you mention. I have been using 1 tsp of hydrogen peroxide to 1 cup water for leaf spray and haven't been getting the results I've wanted. Now I see that my mixture was off. Lol
Woohoo, it works 😊
Well dang I chopped off my squashes first set of true leaves cause they looked silvery
What hose wnd sprayer do you use for spraying peroxide. I have 100 linear ft of trellis and all my melons and squash need to be sprayed. The pump sprayer is tedious when trying to fight powdery mildew!
Thanks for always havjng great content!
Need and whey work wonders
Nothing will bring back diseased leaves. I tried everything.
I did it and it didn't work…now my cucumbers are all covered not sure what to do next
Will this work?
On my zinnia flowers
How much hydrogen peroxide? Did she say a bottle? Or 100 ml?
My whole garden is loaded with blight.
Thank you my darling! My pumpkins have this right now and I didn’t know there was such an easy solution. Appreciate you!
How often do you spray
Exactly what I use on all my plants including my cannabis plants works great
I'm accidentally cutting all my leaves thinking it's mildew I think
