The product information sheet will describe both the recommended dilution and application rates in quite a high level of detail. They are required to do this. It will go into such things as the correct droplet size.
I buy some of these things in 20l drums and store them in a separate locked building. I also keep a book on when, where and what I apply in what volumes not because I’m required to but because I apply different things in different seasons at differing application rates and I want to monitor the effectiveness.
