Root Cleaner Natural Pesticide Soil Drench will stop and eliminate Thrips, Fungus Gnats, Root Aphids and minimize root rot and egg hatching by disrupting their feeding and reproduction. Root Cleaner attacks fungus and algae and cause the pests to dehydrate and dry up. High moisture levels in soils, media and around pots enhances the development of fungus gnats and other pests. If untreated fungus gnats will feed on the beneficial material in the soil. If a fungal food source is not available, fungus gnats may feed directly on plants and inhibit the plant from rooting. This may also damage the root zone as they feed on seedlings and potted plants. On many healthy steamed plants, larvae may tunnel into stems and cause plants to wilt and die. Larval feeding on roots may increase the development of root and stem rots such as Pythium. When this occurs, plants will be stunted with reduced growth. Also, pests droppings on plants may carry other diseases.
