In NY, I know that a signed customer contract is required by law for any kind of application, but how are unplanned apps to be handled? For instance, I won't do a pH test unless the customer will sign up for apps. How would I add a lime app after the fact? Or any other unplanned spot treatments for instance? Can I just write a seperate new contract, or do I have to amend the original one? How do other NY LCO's handle this? Any suggestions most welcomed!
