Sterilite's ability to block out UV up to 380nms, reduces diseases like Botrytis
and Mildew that need a certain level of UV to be able to reproduce, hence by blocking
the UV to this level, you can keep diseases under control without using
chemicals with no adverse effect on the growth of the plants.
Recent trials at Wellesbourne have shown that using Sterilite Premium
Polythene reduced the incidence of mildew from 90.9% down to 43.7%. Flying
insects also see in UV light, but because they can't see they don't
fly.
Trials in XL's own nurseries show that introduced aphids will
form small colonies, but not spread through the house.
The benefit to you is that this all helps to reduce
fungal diseases and aphid attacks, which reduces the need for
harmful chemicals, and the labour costs of applying them.

Sterilite Premium Polythene Full Specification .....
• Partially UV Closed - Sterilite
Premium Polytunnel Polythene blocks out UV up to 380nms. Diseases like
Botrytis and Mildew need UV to be able to reproduce. By blocking the
UV, you keep diseases under control without using chemicals. Recent trials
at Wellesbourne have shown that using Sterilite MDF Polythene reduced
the incidence of mildew from 90.9% down to 43.7%. flying insects also
see in UV light. Because they can't see they don't fly. Trials in XL's
own nurseries show that introduced aphids will form small colonies, but
not spread through the house. The benefit to you is that this helps to
reduce fungal diseases and aphid attacks, which saves you money on harmful
chemicals, and the labour costs of applying them.
• Temperature Control Film - Sterilite
Premium Polythene uses the latest aluminium thermal control additive
which reduces the temperature in the summer better than XL's previous
thermal barrier additives (Calcium). Constant research has developed
the aluminium based Near Infra Red Reflector which has now replaced
the previous calcium based filter to give an extra 10-15% than previously,
making it cooler by day to create a much pleasanter working environment.
• Thermically Efficient - Sterilite Premium
Polythene's thermal filter can save up to 20% on heating costs and
can keep out frosts of up to 4 deg C. It works by reflecting
the stored heat from the plants, pots and soil etc. back into the structure once
the air temperature drops below the temperature they have risen to during the
day. Sterilite MDF Premium Polythene can reflect as much as 86% of this heat
back into the structure. Benefits are reduced heating costs and less damage from
frost.
• High Diffusion - Sterilite Premium Polythene
is a High Diffusion film scattering light as it enters the structure. This prevents
shadows created by the framework of the structure. The benefit is that the plants
don't shade each other and notably grow much more evenly and also give increased
yields.
• Anti Fog / Anti Drip - Sterilite
Premium Polythene has an Anti Fog / Anti Drip agent which breaks down
the surface tension of the condensation droplets so that they run down
the sheet, reducing drips and subsequently retaining light clarity.
• Strong - Sterilite Premium
contains a special metallocene additive, which adds tremendous strength
to the film.
• Thickness - 720g / 180mu film.
• Five Year Life - Sterilite
Premium Polythene has a Five year life Guarantee against
premature UV degradation of film (guarantee terms and conditions apply).
• Use this film - For crops
that you want to grow without using chemicals and all crops that will
be heated. Many growers use this for bedding plants as well as nursery
stock, salad crops etc.
Please Note - Sterilite
Premium Polythene will not totally eradicate all diseases and insect
pests. However as part of an integrated pest management growing system
it will make a significant reduction in pest and disease.
