I got my package to study and will take the test nov. 5-6. 3 manuals and I already know all of it. 2 of them have to do only with law and applying chemicals in general and the 3rd one is a very thin pamplet about turf pests. Of which I've learned on my own basically from reading here at LS. When I got into structural pest control years ago, I found out that "Trumans Scientific Guide" was/is the bible for structural pest control(and I own 5 revisions). Is there a book like that for turf and ornamental pest/weed that most everyone uses? I plan on taking classes to supplement my knowledge also but, there has to be a reference book about this subject.
