New begonia now covered in powdery mildew
Iโve had her for one week. I got rid of the mostly dead leaf in the third photo. Sheโs been VERY close to the other new plants, but I donโt see any mildew on them. She is not one of the rehab plants. I should have given them more air circulation, but now I need to treat her (and maybe the others).
I canโt cut off the diseased leaves/stems without chopping her all the way down. I read that I could wipe the mildew off with a damp paper towel and then treat. I have baking soda, non-peppermint castille soap, dawn liquid soap, copper spray, neem oil, hydrogen peroxide, vinegar, and Trifecta Crop Control (basically a bunch of oils and vinegar). I already have the Trifecta mixed in a spray bottle. I donโt know if I should treat the other plants that were with her

Yes, I would definitely treat your other plants as Downey mildew here is very contagious. I would remove the plant from the others and try to control the mildew with some of the fungicides youโve listed. Weโve been having such weird weather here in Texas with the warm and humid/cold and breezy days that itโs no wonder itโs got the mildew. I guess unless youโre totally attached to it if you just got it a week ago you could maybe take it back (as it probably had it in the nursery) and see if thereโs either a better choice or get your money back. ๏ฟผOtherwise cut off as many leaves as you can. Maybe itโll come back from the root .๏ฟผ Good luck. Oh, and love your polkadot fingernails.
@SucculentBE I was able to wipe off all of the visible mildew. Iโm going to try the Trifecta. It specifically mentions mildew on the front, and itโs already mixed with water for my roses. Itโs a lower concentration, but it will at least give me an idea if the plants donโt like it. I have another empty spray bottle. I might mix two concentrations of it. Lower dose for the plants that were close by and higher dose for that poor begonia
