Due to the fact that many chemical applications are prohibited and that insects have gained resistance to insecticides, Agra Tech has engineered insect screen systems for its roof vents.
The screen system is uses fixed insect screen with nylon brushes to allow the racks to pass through but keep the bugs out.
The screen fabric itself is constructed of UV-stabilized acrylic and polyethylene materials, offering between 4-8 years of protection. Coupling the insect screen with Agra Tech’s smooth running roof vents helps keep insects out of the greenhouse environment.
(The screen is sold separately).
Ingolia also has praise for Agra Tech's customer service and expertise. "From the beginning, James Roberts at ATI was our point person," she said. "He was amazing and was more than willing to help us through every aspect of the planning and construction. It was very helpful to be able to rely on James and tap into his extensive knowledge. We asked a lot of questions along the way and he was always there with the answers."
