I am new to the forum and have been trying to read and understand the terminology on here. Many on here are using acronyms which makes it harder. However since I never have actaully applied anything aside from round up. I am lost with the chemical app process. The NC pesticide class was a joke. I passed with ease since I am good wih math and have common sense. The class never talked about calibration, application rates, chemicals used, and how to clean tanks afterwards. I went to local Lesco dealer thinking they would help and have some good reading material and they were no help with chemicals, rates, and programs. I inquired about purchasing a skid and how to calibrate, clean when finished with different apps etc. I have also tried using this sites search for many answers but a lot of them are not there. I would appreciate any links or pointers on how to move forward and become more educated with the app process. I am looking at purchasing a Permagreen combo. I want to focus on fescue only for this season and slowly add from there. I would really appreciate any help.
