TCT 40×40 insect net is a high‑density polyethylene mesh used to protect vegetables, fruits and nursery crops from harmful insects and virus‑carrying pests. The 40×40 mesh size provides a fine barrier that stops common pests such as whiteflies, aphids and leaf miners from entering the crop area while still keeping ventilation at a comfortable level. The net also reduces the need for frequent insecticide spraying, helping growers cut chemical costs and produce safer, cleaner crops. Supplied in a 3 m x 50 m roll, it is ideal for covering greenhouse sides, shade‑house walls, net‑houses and field tunnels, and can be installed on wooden, steel or PVC structures. UV‑stabilised material ensures long‑term durability under strong sun and outdoor conditions.
