It's not for lack of information, that's for sure. For example:

> IPM is integrated because it brings together, or integrates, a range of biological, organic, cultural, mechanical, and chemical options for pest problems. And IPM is about more than just bugs -- it's also about fungi and mildew, bacteria, viruses, weeds, and wildlife, all of which can be pests if they’re in the wrong place at the wrong time. And it’s about management because you can only manage pests -- you can’t get rid of them forever, no matter what anyone tells you.
