OK, I read this back in the 80s or 90s, maybe even early 2000s. Humans have colonized another planet. Things haven't gone to plan. There's a good guys group and a bad guy that controls the supply of potassium that everyone needs for good health. There's plants, but few or no large animals on the planet. There's a problem with insects and the good guys spend a fair amount of time trying to come up an insectivore to fight them. They eventually clone bats, IIRC. The bad guy is the only one with seeds for a potasssium rich plant. (view spoiler)[At the end, there's a struggle between the main character and the bad guy that results in some of the plants being seeded into the local soil, thus ending his monopoly on potassium. (hide spoiler)] One character uses teflon cookware and talks about how nothing sticks to it. That's all I can bring up at the moment.
