PEPP (Plant Extract for Plant Protection) is a natural plant protection agent developed by TOKU-E that contains plant extracts to combat bacterial and fungal pathogens. Natural plant extracts have been used in the pharmaceutical and cosmetic industries since they generally have low toxicity to plant and mammalian cells. PEPP does not contain any antibiotics._x000D_ PEPP has activity against bacteria and fungi without inhibiting plant growth. It is a proprietary blend of an essential oil plant extract combined with a water-based plant extract. The water-based component will act on contact against bacteria and fungi while the essential oil will act as a surface protectant._x000D_ Extracts have been carefully balanced for maximal protection and non toxic formulation. Protection occurs with application and eventually, the plant extracts can be taken up by the plant as a nutrient source. An advantage of this formulation is to counteract the plants’ resistance to antibiotics that have been used for plant protection._x000D_ In order to arrive at the PEPP formulation, 189 different extracts from 63 different plant species were screened using 3 different extraction methods (water, steam, ethanol).
