SNS 244 Fungicide is made up of 100% pure thyme botanical extracts, and works to kill fungus affecting plants, vegetables and trees. Components of SNS-244™ are absorbed systematically by the plant, suppressing the life cycle of the fungal spores and nurturing the plant cells to increase its immunity to disease. Strong enough to treat trees, but delicate enough to be used on new growth, clones, leafy foliage like lettuce or roses.
