Crude extracts from the root and leaf both sections. Per seed germination and growth of rice and spinach and grass, birds. Bring the test per seed germination and growth of the plants tested at concentrations 1000, 2000, 4000 and 8000 ppm, by a test with two kinds of plants are grasses, rice birds (Echinochloa crus-galli (L.) Beauv.) and Amaranthus (Amaranthus viridis L.) from the experiment found that the extracts at 8000 ppm concentrations in place.Cycle of a bird can be stifling and spinach rice grass has the highest secondary is both the beginning and Foundation, respectively. The result of the separate parts from the Tiger with a chisel Lake, respectively, is the pole of the organic solvent hexane layer of seed germination of the grass, the bird can resist rice is higher in acetic ethyl floor hotel suite. 70% alcohol and floor layers flattened butanol In the best floor hotel suite of acetic ethyl Can inhibit seed germination in spinach is much higher than in the hexane layer. Shelf alcohol 70% and latam butanol series. In the part of seed germination in hexane layer can inhibit seed germination in seeds, spinach is much higher than in the best floor hotel suite of acetic ethyl. 70% alcohol and floor layers flattened butanol respectively this outcome suggests that Tiger Lake may be applied for control of weeds in the future.
