FiltersDisease Control
Anti-Petal Blackening of Red Roses
- Facilitate the removal of dust, soil and dirt stuck on the outer greenhouse surface with rain or a simple wash
- Prevent decrease in the amount of light transmitted through the greenhouse cover
Reduce surface tension of condensing water vapor, so that condensation trickles down the plastic wall of the greenhouse film, preventing:
- Damage and disease caused by water dripping
blooms and leaves, reducing the need for
pesticides
- Scorching of plant leaves caused by sunlight
on water drops
- Up to 30% reduction in light availability caused by water droplets on greenhouse film surface, resulting in earlier harvest and higher yield
Avoid usage on structures with metallic supporting wires
Ventilate and/or heat the greenhouse to remove the mist that usually occurs at sunset and dawn
The anti-fog effect lasts up to 2 years, since the additive migrates to the suface of the film and is slowly washed out by water
Due to the complex mechanism of its activity and the different parameters affecting its function, MASTERPAK does not provide a warranty for the effectiveness and the duration of the anti-fog performance
In addition to the infrared additives benefit with the EVA additive from:
- Increase in transparency due to a reduction in crystalline patterns
- Enhancement in the film mechanical properties
- Increase in heat resistance on metallic greenhouse structures
Optimize light diffusion inside the greenhouse cover without decreasing light transmission: prevent shadow spots and reduce high energetic sun rays, resulting in:
- Better environment for plant growth during hot season
- Better crop quality and higher productivity
Minimizing temperature fluctuation:- During the day, slightly decrease temperature inside greenhouses by
blocking near infrared radiation (NIR; 750- 1400 nms) outside thermal
greenhouses
- During the night, increase temperature inside greenhouses, by
creating a barrier to far infrared radiation (FIR; 3,000-14,000 nms)
reflected by the soil
Resulting in:
- Earlier harvest, higher yield and better quality and uniformity of crops
- Reduced evapo-transpiration, which increases sugar and taste quality of produce
- Substantial energy savings when heating greenhouses
Break sun radiation into a multitude of rays, optimizing the even spread of light within greenhouses, which:
- Increases efficiency of photosynthesis when covered areas of self-shading and trailing plants receive light
- Decreases phototropism
- Decreases potential for sunburn on blooms and leaves
Optimal light diffusion does not impair light transmission. MASTERPAK produces films with different levels of light diffusion, according to your climate and crop requirements
UV Absorber should not be used in greenhouses requiring insect pollination
- Inhibit degradation of PE polymers in greenhouse film without blocking UV radiation
- Contribute, along with Photosynthetically Active Radiation (PAR), to the organoleptic properties of vegetables, fruits and flowers
- Stimulate natural bee, bumblebee and other insect pollination
Filters
Block UV sun rays (up to 380 nm):
- Causing insects to lose visual ability inside greenhouses, preventing viral, fungal diseases and crop damage caused by white flies, aphids, red spiders, leaf miners, thrips and other insects
- Resulting in substantial decrease in dependence on and use of agricultural chemicals, contributing to Integrated Pest Management (IPM) programs
Disease control films should not be used in greenhouses requiring insect pollination
Block Far Infrared and UV light (up to 380 nm), preventing rose petals from blackening in strong sunlight
