I've used the Weed Free Zone on my lawn in the past with good results. What's the difference between Weed Free Zone and the Weed Out? Specifically, does one do more weeds, is one safer for lawns, does one last longer? The Weed Out seems a little cheaper. I live in Central Pa and have Penn State mix grass.
These products have slightly different formulations. Ferti-Lome Weed-Out with Trimec contains:
Mecoprop dimethylamine salt - 5.45%
2,4-dichlorophenoxyacetic acid - 5.88%
Dicamba - 1.21%
Weed Free Zone contains:
2,4-D, 2-ethylhexyl ester - 10.49%
Mecoprop-p, acid - 2.66%
Dicamba, acid - 0.67%
Carfentrazone-ethyl - 0.54%
Weed Free Zone is a newer formulation made for faster results, but since it is more aggressive, it should not be used on improved varieties of St Augustine turfgrass.
