Greenhouse plastics create an environment that, when humid and warm, becomes a breeding ground for mold growth. This common issue affects plastic structures like covering sheets and agricultural films. As a result, unsightly staining, discoloration, and overall product deterioration can occur. This ultimately forces premature disposal and replacement, significantly contributing to landfill waste.
The demand to increase agricultural productivity and feed a growing global population highlights the necessity for polytunnels constructed with plastic materials that are treated to deliver enhanced durability, UV stability, and light transmission.
Dr. Mai Ha, Senior Product Development Engineer at Microban International, recently provided expert commentary and insights in an article featured in Greenhouse Grower. The article delves into a new strategy for preventing mold development on greenhouse plastic and looks at sustainable alternatives to arsenic-based formulations for long-lasting protection.
