Mazzie's are fine if you have enough water pressure to run them. Most Mazzie's require a pressure drop of 10-15 PSI to make then work right. If you only have 45 or 50 PSI at the faucet and need to run water hundreds of feet to the field, well then they may not work well.

They also require a minimum amount of water flow to meter properly. They don't work well on small plots. They are great on large fields.

A cheaper injector, like a Chemilizer, will work great. They are essentially like a budget dosatron. It is a fixed 1:100 injector for about $200 at Nolt's Midwest Produce Supplies. It sucks a concentrated solution and injects it with virtually no loss in water pressure. It is a constant rate injection as well so there should be no burning unless you miscalculate on your concentrate.
