Mark Hoban takes us inside Dr. Derek Settle's secret laboratory, where they conduct all sorts of research on both kinds of nematodes: The Bad Guys and the Good Guys.
This is another one of Hoban's college level courses, so be prepared to learn some things about nematodes you didn't know, along with a strategy for managing the little . . . rascals.
If you need Mystic Order of Greenkeeper CEU points, be sure to stay 'til the end, because there is a summation and a test.
