CloseSNS 209 is an effective foliar spray against spider mites, broad mites, russet mites, root aphid larvae, thrips, fungus gnats, cabbage maggots, and more. SNS 209 works by allowing plants to absorb small amounts of rosemary oil and distributing it throughout their cell walls. This creates a barrier that insects don’t like, causing them to stop eating, move on, or die.
Insects destroy plant cells by chewing up cell walls and sucking out fluids. 209’s unique formula works by allowing the plant to uptake a small amount of rosemeric acid from the rosemary plant. As the plant distributes the rosemeric acid throughout its cell walls, a barrier is soon constructed that is harmless to the plant. When an insect starts to suck or chew on the plant it comes in contact with the rosemeric acid and causes the insect to stop eating and move on.
209 is made up of 100% pure botanical extracts that are highly water-soluble. Sierra Natural Science processes raw certified organic botanicals and herbs in-house, ensuring oils and terpenes have a consistent potency across all products. The botanical extracts are all food grade GRAS (generally recognized as safe) materials, that are fully biodegradable, and not toxic to animals. This product is exempt from EPA registration under minimum risk pesticide under FIFRA section 25(b). It can be used on a wide variety of plants, fruits, and vegetables.
