Arrigoni engineers in cooperation with experts in the field of entomology developed a wide range of Biorete insect screens which can provide insect control against most invasive insect species in plant production, from large ones to even the smallest like Thrips. Years of intensive research, insect measurements, experiments in laboratory and open field and application of new technologies and materials in yarn production resulted in very precise hole dimensions on screens, adjusted to different sized groups of insects.
Screen recommendation is based on insect size dimensions that a producer wants to exclude from greenhouse, therefore the hole size is very important. Smaller insect species require smaller hole size of insect screen, but every reduction of hole size is followed by lower air exchange. As a result of air exchange reduction in greenhouses, the humidity and temperature can be very high especially in summer days and warm climates.
Greenhouses trap solar radiation and humidity, creating on one side undesirable conditions for plant growth and on the other, excellent conditions for development of pathogens, associated with high humidity levels. In conditions of low air exchange the ratio CO2/O2 change and affect the most basic plant functions like photosynthesis and rooting.
To create even more comfortable microclimatic conditions for plant development and high cropping, Arrigoni group went one step further and developed a new Air Plus line of Biorete screens. Better insect screen structure (low thickness monofilament in high strength with same hole size) enabled to get a greater number of holes by m2 and ventilation increase for 32%. At same time, improved screen structure offers the same level of protection against different insect species.
Improved air movement under the Biorete Air Plus line of screens provide significant benefits:

Better communication between plant and environment
Air circulation creates uniformity in temperature and humidity, fresh air for better plant nutrition and wind for pollination process and strong plant growth.
Healthier plants and good production
Air movement improves humidity conditions in greenhouses. A dry and protected plant habitat means less insect damages, fungal and viral diseases, vigorous and healthy plants with high production of quality crops.
In step with environmentalism, high cropping and safe food, next to standard Biorete screens, today Arrigoni company can offer producers an Air Plus line of screens with different hole size (25/50/80 mesh) for better climate and biological control of most invasive insect species like Thrips, Aphids, White fly, Drosophila suzukii…
