Although this test study was conducted on conifers, it clearly demonstrates the effectiveness of Moisture-Loc in reducing transpiration. The tree that was treated with Moisture-Loc at a 20:1 concentrate, cut at the base and left out in the elements for over two months is still green and pliable. Moisture-Loc also provides a clear prophylactic barrier that protects plants and trees against insects and disease. Imagine how this product could work on vines in preventing numerous costly issues. Moisture-Loc also mixes well with other water-soluble ph neutral chemicals (fungicides), enhancing the longevity of your chemical application. 

Feel free to ask for a sample and conduct your own test.
