Fly net stretched over ventilation ducts in greenhouses plays an important role in protecting plants from pests by saving on chemical pesticide use. Antivirus fly nets are designed specifically to protect seedlings and plants grown from whiteflies, tufa and similar pests. There are nets with different mesh sizes, usually called 25, 40 and 50 mesh.
Standard tulles are usually 1.00 - 1.20 - 1.50 - 2.00 - 2.50 - 3.00 3.50 - 4.00 meters wide and 200 meters long. However, stitched tulles can also be provided in special sizes. Imported fly net products can be found in stock throughout the season.
Tulles with a mesh size of 50 mesh have a slightly wider structure. In this way, while the ventilation of the greenhouse is more comfortable, the entry of pests such as the tuta moth, other butterfly species and whiteflies into the greenhouse is prevented.
