Greener Than You Think

Man loses control over the outcomes of a scientific experiment the only aim of which is to create a way for the greediest man on earth to become even richer. The experiment is conducted on Bermuda grass, a harmless plant in its initial form, but one that becomes murderous and powerful after the salesman protagonist of the novel applies a fertilizer spray called the Metamorphosizer created by a female chemist on it. The metamorphosis of the grass is very quick - it starts growing with incredible speed and soon it turns out that nothing can destroy the new species of grass, it feeds on anything and grows over anything. In the beginning, the grass grows at the same pace as its owner rises to prominence and wealth, but things get out of control very soon and it takes a team of the bravest to stop the murderous plant.
