SNS 244 Ready to Use Natural Fungicide is made up of 100% pure Thyme extracts. The botanicals are all food grade GRAS materials. Airborne disease causing fungi get inside the plant and either poison and kill the plant cells before absorbing food from them or simply steal nutrients from the living cells. Some fungi live in the soil and enter roots and can either block the water-conducting cells or kill them causing the plant to wilt. As a topical spray SNS 244 kills the fungus through a biochemical interaction on the spores. Some of the components of SNS 244 are also absorbed by the plant suppressing the life cycle of the fungal spores and nurturing the plant cells to increase the plant’s ability to fight the disease.
