Sorry, never read that, but I've seen 2 different screen adaptations of Andromeda Strain, and neither of them would be considered "good". The most recent version was made for TV, so not as large of a budget as a true feature and more disappointing that it wasn't better than it was for being the redo.

However, since this is carneverous plant stuff, if they start getting too big for their britches, we can use dandruff shampoo according to sily scifi plot lines instead of fire. That way it won't get out of control. The lastly, since we're not sure the effect of fire, it might be best to just take off and nuke it from orbit.

Most of his other books were very worth reading though.

I haven't read any of the above, but while we're on the topic of dangerous fictional flora, I can recommend:

The Day of the Triffids by John Wyndham

The sequel also makes a good read. The human angle might be slightly overplayed, but it hits the Crichton style quite well with computer analysis, foreshadowing and the tech dread.

Of the later works, Dragon Teeth (posthumously published) is worth checking out - no high tech but more a scientific western story.
