Hello
I have some Drosera seedlings and there is white mold growing on the surface of the peat moss among the seedlings. Do you know of a good way to kill it or stop it spreading that does not involve a chemical that is toxic to humans? It would be good if there is something that is safe to spray or water on the surface where no gloves or mask is needed.
I also have slimy algae on the surface of the soil and it would be good to also find something to reduce that.
I have tried 1 part pasteurized cows milk and 10 parts water and also 1 part 3% Hydrogen peroxide and 3 parts water. However, they did not make much difference. I heard that alcohol could work but I am not sure how much water I should mix with it and how much to apply to the seedlings. I read that cinnamon can help but it also is a growth inhibitor.
I do have some Azamax which I think is similar to Azadaracton or neeme oil which supposed to control fungus. However, my Azamax is about a year past it’s used by date.
Some other suggestions are below. However, I am not sure if they could harm the plants.
•1 tablespoon of baking soda
•½ teaspoon of liquid soap
•1 gallon of water

Do you think any of the above would be a good fungicide for Drosera seedlings and should I water the mix in or is it best to just spray it on?
Your help is appreciated
