SNS-203 Concentrated Natural Pesticide Soil Drench & Foliage Spray

SNS-203 Kills and Repels Fungus Gnats, Root Aphids, Thrips, Shore Flies and Whiteflies.

SNS-203 is made up of pure Rosemary and Clove botanical extracts.

How it Works
SNS-203 Concentrated Natural Pesticide active ingredients attack fungus and algae to reduce the food source for the pests and cause the pests to dehydrate.

Directions for use:
Soil Drench: Mix 2-4 oz of SNS-203 per 1 gallon of water. Thoroughly drench affected and surrounding area.
Foliar Spray: Mix 2-6 oz of SNS-203 per 1 gallon of water. Spray Foliage to point of runoff.

Repeat 2-3 times as necessary. Do not mix with other chemicals or fertilizers.

Directions for Use in Hydroponics:
If you can remove plant from system
- Remove plant and place in 5 gallon bucket.
- Pour solution over top of the root system down and drain into the bucket.
- Let sit for 5-10 minutes.
- Rinse with water and return plant to system.
- Apply 2-5 times every 2-3 days as needed, depending upon infestation.
- You may reuse the solution in the bucket, simply strain unwanted pests and set aside. The product is good for 2 years after expiration date marked on bottle. Keep out of sun and away from extreme heat.
If you cannot remove plant from system
- Pour solution over the top of the root system down and let it drain into the system.
- Use on each individual plant, pouring over top of root system.
- Apply 2-5 times every 2-3 days as needed, depending upon infestation.
- Make sure to flush system appropriately after use. SNS-203 should not be left in a reservoir.

CAUTION: Do not use with other products.
