I am an office mgr for a L&T management co in Maryland. By law we are required to keep detailed records of each pesticide application. One requirement is to list the mix rate, total amt applied as well as the concentration rates of the pesticide in question. We have been doing this since 1993 and the "CONCENTRATION RATE" eludes me to this day. What the MDA is looking for in these records is clearly not the concentration rate listed on the MSDS. Where can I find the answer? Thx.
