 SURROUND
forms a white barrier
coating on crops, which helps
to protect them from sunburn and
heat stress. The particle barrier
is specially designed to allow
usable light through while blocking
harmful infrared (IR) and ultraviolet
(UV) light.
The technology behind Surround
crop protectant was co-developed
by Engelhard
Corporation and the US Department
of Agriculture and is referred
to as 'particle film' technology.
Comprised of specially modified
particles of kaolin, a naturally
occurring material, Surround is
mixed in water and sprayed onto
crops. Upon drying, a fine white
film results. If Surround is applied
to an edible part of the plant
the film can be washed off at
harvest, or spraying can cease
early in the season and the deposit
weathers off naturally.
