Surround on Pears
Reduce the devastating effects of pear psylla in your orchard with Surround crop protectant!
An infestation of pear psylla is problematic because of its unusual ability to:
- Develop resistance to chemical control, and
- Secrete copious amounts of honeydew that grows a black fungus making fruit unmarketable.
Heavy and prolonged infestations can result in tree stunting (psylla shock), reduced fruit set and size, and even death of the tree.
Always Read and Follow Label Instructions
Recommended in the Research
Carefully timed treatments of Surround Crop Protectant can significantly
suppress the activity of pear psylla, delaying or even eliminating the need
to apply conventional insecticides.

Delivers Additional Benefits
Calcined kaolin clay
Surround is made of high-grade kaolin, that is highly purified so as not to contain measurable levels of crystalline silica.1 Crystalline silica is a pulmonary carcinogen that is common in crude kaolin products that are not purified with the same care as Surround.2, 3
For organic growers, the insect suppression properties of Surround provide an especially valuable tool in managing insect populations. Surround is certified for use in organic production systems in the USA and in Europe.
Reduction of sunburn losses by up to 50%
The calcined kaolin particle film of Surround protects fruit against direct sunburn and heat stress damage
Cooler plant canopies
Photosynthesis is more efficient, and yields can be higher in high light and heat environments when canopies are kept up to 7° F cooler.
