Organic IPM Tool for Reducing Insect Pressure in Pistachio Trees
Repel Damaging Insects From Pistachio Trees
Insect Suppression
Developed in conjunction with the United States Department of Agriculture (USDA), Surround® is formulated to suppress insect activity and can be a valuable tool in pistachio IPM programs. SURROUND is an EPA-registered insecticide that can help reduce the damage caused in pistachios by aphids (such as pecan, black and yellow aphid), stink bug and navel orangeworm. In addition, SURROUND may be used to maximize the effectiveness of conventional insecticides by avoiding their overuse, thus minimizing the likelihood of insect resistance. SURROUND is OMRI-listed for organic pesticide use.
SURROUND functions best when used as a preventative program, applied to the tree before the pest appears. SURROUND will reduce pest pressure and may eliminate the need for additional treatments. If pest pressure reaches an economic damage threshold, a knockdown insecticide should be used. SURROUND may be tank mixed with most crop protection products.
SURROUND may suppress beneficial insect activity. Closely monitor and employ a typical control program for scale and mite.

Nine Ways SURROUND May Suppress Insects
- Repellency
- Impedes egglaying
- Reduces feeding
- Impedes grasping
- Restricts movement
- Camouflages the host — prevents host recognition
- Alters behavior
- Induces paralysis
- Causes mortality
Recommendation for Nut Crops
Volume: Apply to near-drip, not to excessive run-off. For 20-foot trees, it is best to use 200 gallons per acre. Large trees like walnut and pecan can require up to 300 gallons per acre.
Concentration: It is best to use 25 to 50 lbs SURROUND WP per 100 gallons of water.
For Tree Nuts: Such as almond, beech nut, Brazil nut, butternut, chestnut, cashew, filbert, hickory nut, macadamia nut, pecan, walnut and pistachio
| Pest | Pounds / Acre | Application Instruction |
| Aphids such as pecan, black and yellow aphid, codling moth, grasshoppers, husk fly, leafhoppers, naval orangeworm, stink bug | 50-75* | Suppression only**. Start at biofix or as infestation occurs. Apply every 7-14 days throughout infestation. For codling moth, apply a minimum of 2 sprays per generation. |
| *50 pounds per 200 gallons per acre preferred. *If complete control is needed, consider using supplemental controls. |

Application Tips
- Avoid foliage run-off. Apply the spray volume that will achieve near-drip.
- Best results usually achieved at 25-50 pounds per 100 gallons.
- Surfactants may improve spreading.
- Consult the specimen label for instructions on aerial application.
- See SURROUND spray guide for more information on effective application techniques.
Always read and follow label instructions.
