Surround WP (25 lb) (OID COMM)
Protect Against Insects, Disease & Sunburn
Surround WP is a crop protectant made from Surround kaolin clay, a naturally derived mineral widely used in organic agriculture. Available in a 25 lb bag, this OMRI-listed product forms a protective white film on plant surfaces, creating a physical barrier that helps reduce insect activity, prevent sunburn, and minimize heat stress.
What Is Surround WP and How Does It Work?
Derived from processed Surround kaolin clay, Surround WP crop protectant creates a uniform coating on leaves, stems, and fruit. This coating deters a range of insect pests by making plants less recognizable or attractive for feeding and egg-laying. Additionally, the reflective properties of the film help lower surface temperatures and shield plants from excessive sunlight.
Because Surround WP acts as a physical barrier rather than a chemical control, it’s favored by organic growers looking for non-toxic, environmentally friendly pest management options.
Key Benefits of Surround WP
- Natural and OMRI-Listed: Made from 95% kaolin clay, Surround WP is approved for use in certified organic farming.
- Insect Deterrence: Discourages pests such as Japanese beetles, codling moths, flea beetles, and pear psylla by interfering with their ability to feed or lay eggs.
- Sunburn Protection: Reflects harmful UV rays, helping protect fruit and foliage from sunscald.
- Heat Stress Reduction: Keeps plant surfaces cooler by reducing solar heat absorption—particularly valuable during hot, dry periods.
- Broad Crop Use: Suitable for fruit trees (apples, pears, peaches), fresh market vegetables, field crops, and other high-value plants.
Pests Controlled by Surround WP
Surround WP is labeled for use against a range of insect pests, including:
- Apple maggot
- Codling moth
- Japanese beetles
- Oriental fruit moth
- Cucumber beetles
- Flea beetles
- June beetles
- Rose chafers
- Eastern tent caterpillars
- Pear psylla
By disrupting pest behavior and reducing feeding, Surround WP crop protectant can help minimize the need for conventional insecticides.
How to Use Surround WP
To apply, mix the Surround WP powder with water according to the label directions to form a smooth suspension. Use a sprayer to achieve full, even coverage of all plant surfaces. Reapply as needed, particularly after heavy rain or rapid new growth. Always consult the product label for detailed instructions and recommended application rates for specific crops.
For best results, apply early in the growing season before pest pressure peaks.

I have a big Fuji Apple tree which coddling moth just loves. Every year it grows dozens of dozens of apples and only about a handful are worm-free. The first year I applied Surround WP it was completely opposite: only a handful of apples were wormy, and absolute majority were worm-free! I’m so happy!
Good product and quick service and shipping.
We started using Surround on our very large vegetable garden and so far it's doing a great job in helping control pests.
Just sprayed this on our olives and apples last weekend, very easy to mix up. Used 3 cups to one gallon in handheld hudson sprayer. DO wear long pants and sleeves and I also wore a mask and hat because you will get covered in the stuff spraying it. Glad to have something organic to deal with pests. This is my first time using this product so I don't know how effective it is, but others seem to think it works really well. Hopeful.
I apply with a Hudson trombone sprayer. 1 cup of the kaolin clay weighs approx. 2.5 ounces, so approx. 6.5 cups is equal to one pound.
