Guest Monkey Shines Posted June 14, 2002 Would hydrogen peroxide be a suitable alternative to using other nasty fungicides like CHINOSOL for cactus germination and seedlings, and what concentration should be used? Share this post Link to post Share on other sites
Auxin Posted June 14, 2002 H2O2 is not just a fungicide, its a biocide! It kills all living tissue. With larger (or more well protected) seeds it is possible to use a breif treatment with 1% or less and not kill too many. Any H2O2 will kill cacti seedling roots. Real fungicide is best.

Guest Monkey Shines Posted June 22, 2002 Are there any fungicides that can be safely used indoors? Share this post Link to post Share on other sites
waterdragon Posted June 23, 2002 i believe baking soda has its uses, can't remember the source of that info so look into it. Share this post Link to post Share on other sites
Torsten Posted June 23, 2002 macadamias are often treated with a dilute solution of potassium permanganate (condy's crystals), but don't ask me what dilution they use. Sulphur dust keeps a lot of fungus at bay, especially in respect to cacti. And a little copper (copper oxychloride) should be OK too. Share this post Link to post Share on other sites
