Know before you buy
SNS 209 is a systemic pesticide, meaning the plant absorbs the botanical extracts through its roots or foliage. Once absorbed, it creates an internal barrier that makes the plant tissue unpalatable to insects, effectively repelling them from the inside out.
Yes, SNS 209 has a 0-day pre-harvest interval. Because it is made from food-grade botanical extracts, you can safely apply it up to the day of harvest.
Yes, the formula is non-toxic and safe for use around children and pets. It also features a 0-day re-entry interval, so you do not need to wait before allowing them back into the treated area.
The standard dilution rate is 1/2 tablespoon (1/4 ounce) of concentrate per 1 gallon of water. Always mix thoroughly before applying via foliar spray or soil drench.
SNS 209 is not selective, so it is not recommended for use if you are actively trying to preserve beneficial insect populations. It is designed to target a broad spectrum of pests, including mites, aphids, and fungus gnats.
For ongoing protection, apply the solution bi-weekly. Because the product has a residual effect of approximately 21 days, this schedule ensures your plants maintain a consistent internal barrier against pests.
