What solution would be appropriate to kill them we have your liquid copper fungicide. They keep coming back can we increase the dosage?
Southern Ag Liquid Copper Fungicide is not labeled to control mushrooms. and should only be mixed and used as directed on the label We do not have any products to control mushrooms in the lawn. Spores can be in the soil for years before the conditions are right for the mushrooms to grow. The best thing we can recommend is checking the drainage conditions such as sunlight, runoff, leveling/low spots, soil pH, and turf health to help mitigate concerns about mushrooms.
We recommend you contact your local cooperative extension office and get the mushroom identified. The master gardener on staff should be able to tell you what will work to eliminate the type of mushroom you are dealing with.
