So... I'm in the process of becoming licensed for liquid pest/herb applications. I just spent the last hour searching and reading posts on this subject. I don't want to bore anyone with all the beginner questions, save one... What is the recommended reading (books, articles, websites, etc.) on this subject? My certification procedures don't begin for a few more weeks and I'd like to do some reading before hand to at least have a basic grasp of the equipment and chemicals, their use and applications. Thanks in advance guys.
