Science fiction book about world overrun by grass

Question

It was a great book done as an anti-version of Christopher's The Death of Grass, with a touch of black comedy.

The story was about a botanist working on a formula to improve crop yields and a stupid salesmen causes the formula to be released and it affects grass in the cracks of the street.

Within days there is a hundred foot high tuft of grass turning into a jungle that begins sweeping across the US and eventually the planet, resistant to man and bomb and all tools imaginable.

It ends on a research boat at sea where they are desperately hunting the cure, but all goes wrong again....

Answer 1

It's Greener Than You Think by Ward Moore, published in 1947. Actually, way before Christopher's The Death of Grass, that was published in 1956.

Written in 1947, a science fiction novel about the grass we tread upon. When an unscrupulous salesman sprays a dying suburban Los Angeles lawn with an untested chemical spray, it is the beginning of the end of the world. The grass begins to grow uncontrollably and riotously, ten feet hight, thick, tough, inpenetrable, gradually engulfing Los Angeles, then California..After reading this novel, you will never view your lawn in the same way.
