Use in yards

I have a HORRIBLE Horsetail problem in my yard. It's fully landscaped and they come up everywhere. I've tried everything I've read about, but come Spring they are back with a vengeance. How would I use this is my environment??

Answer:

Casoron 4G is a pre-emergence herbicide that kills selective weeds and grasses.  Casoron 4G controls weeds before they emerge from the ground,  by forming an herbicidal vapor barrier in the upper layer of the soil when activated by rainfall or irrigation water.  Casoron 4G should be applied before weed seed germination and emergence from the soil (usually from mid-winter to early spring).
