Many insects cause direct and in direct damage to plants.Direct damage ranges from sucking liquid from the plants to marks on the leaves.Much more serious indirect damage is determined by the fact that some insects are carriers of viruses and this causes a reduction of production, fruit malformation and withering of the plant until it dies.
The insects most frequently affecting plants (especially the tomato) are Trialeurodes vaporariorum better known as the “white fly” which transmits generic viruses, Bemisia tabaci and Frankliniella occidentalis which respectively transmit the Tomato Spotted Wilt Virus (TSWV) and the Tomato Yellow Leaf Curl Virus (TYLCV) Chemical and microbiological control means are undoubtedly effective in terms of their power for controlling insects, but before being killed by the insecticide used in the greenhouse, they prick the plant and transmit the Virus damage on tomatoes.
To prevent insects from entering greenhouses, a physical barrier is now used. This is a woven mesh with different mesh sizes according to the insect to be defended from.This type of protection is used all over the world and prevents virus carrying insects from entering and keeps down insecticide treatment for controlling other harmful insects

Agriculture Protection nets made by Arrigoni are produced by using 1st quality polymers supplied by the most important European producers.
UV ray stabilizing process in yarn extrusion step is arranged by specific active ingredients which ‘defend' the fiber from its natural degrading.
2.Specific Mixing System
The equipment used to carry out the bond among HDPE polymer and its additives (UV stabilizer and color master, if any) is really specific one (gravimetric blender), which assures an excellent and regular distrubition of mentioned additives in the polymer batch mix, by using automatic ‘weighing' system as mixing parameter, instead of ‘volume', or simple human operation.
3. Production Process
All machineries available in our production plant are modern ones (manufacturing year is after 2000) and allow to reach maximum strenght and durability of the product.
Production process (spinning step and weaving/knitting step) is performed by high qualified operators, inside the factory, so the company is in condition to have an high level of product quality, having all production steps under direct control.
4.Quality Management System
The company is ISO 9001:2000 and ISO 14001:2000 systems certified, and since 2007 is included in the EMAS registered company list; Eco-Management and Audit Scheme is a management tool for companies to evaluate, report and improve their performance with environmental respect goal.
5. Net Identification (Tracing Monofilament)
To be sure that Arrigoni company is the producer of the net, a special type of monofilament is used inside the net as ‘producer identification' or ‘tracer', on warp direction, which assures ‘optical' (under special light exposure) and ‘chemical' tracing possibility.
The company has an internal testing laboratory, equipped with various instruments to check quality, strength and life of the product: n, 28 net samples are constantly under test.
7. Product Defect Responsibility
In case of demonstrated net defect or net degradation,the responsibility of Arrigoni is only limited to net replacement; the replacement will be assured according to residual life of the net.
