Mold problem on house plants any suggestions?

Question

Several of my houseplants keep getting a white film/mold all over the leaves that I cannot get rid of it. It is white & powdery and seems to spread to neighboring plants within the room. I have tried lightly washing with dish detergent, spraying fungus spray from the garden center, Listerine, Tylex mold & mildew remover (yes, I’m desperate) and still it comes back. Anyone have suggestions on what to try next?

Answer 1

It does sound like powery mildew and you may have also hurt the epidermis of the leaves with something with a pH as high as Tylex and mildew remover. To get rid of the disease get daconil or Bonide calls it Fungonil--same thing. Spray the bottoms and tops of the leaves every 10 days for three times. This fungicide is not labeled for indoor use so you should take it to the garage to spray it and leave it there until it dries (provided your garage is heated or at least not freezing). Ten days after the 3rd time use a mild solution of luke warm water and detergent to wipe off the dead mildew. In nature many rains would wash off the dead fungi but it won't rain in your house.

If you can't spray anywhere except in you house use Houseplant Fungicide by Safer. If your garden center doesn't carry Safer get any sulfur based fungicide and use it. It's not quite as good at controlling powdery mildew as daconil but you have to be safe. Follow the same procedure as above but after you've cleaned the leaves after the third sparying, spray them about once a month for a few months to make sure it doesn't come back. With the daconil these additional sprays are normally not needed.

It is probably what is called powdery mildew if you have checked to see if it is not bugs. Place a white piece of paper under the leaves and tap the leaves - if little spots come off you have spider mites not mildew. Both problems can be treated with stuff you can buy at Lowes.

Answer 3

you've a nasty blend problem: intense water table and in all likelihood heavy impermeable clay soil. The Habitat human beings are those right here that would truly help you. there's no longer something you are able to do your self, and they are the leads it appears like on the challenge. also the community progression officials might want to be keen on this as web site progression must have protected hurricane water runoff and settlement ponds to address it. If an underground spring or artesian properly is close to or on your belongings there are massive issues that choose addressing at the moment. I first idea that your fence human beings drilled into an underground water line.

Answer 4

The best thing that I found was Consan20. It can be used for mold or fungal proplems. Test it first on a leaf to make sure it does'nt harm the plant. Your local hardware store or nursery should have it.
