It's not just the products, but how you use them that matters. Our pursuits in better application methods have led to optimized efficacy and maximum public health and safety. While our group of companies are credited with the early advancement of tarping, it was ongoing work, strategic partnerships, and new technology that led to the recent development and use of Totally Impermeable Films, or "TIF." TIF has dramatically improved soil retention resulting in greater safety and efficacy. TriEst was quick and thorough in our adoption of Good Agricultural Practices, or "GAPs", that has led to the highest levels of performance and safety. GAPs were put in place by the USDA to ensure proper procedure, productivity, and quality. TriEst was early to adopt GAPs even before the practices became mandatory.
