Controlling marestail / horsetail with SBK and KPlus+

It is highly recommended that you use the adjuvant KPlus combined with SBK to enable the triclopyr to break down the silica outer layer of the horsetail and increases its ability to penetrate into the weed achieving greater results.

For marestail/horsetail control, it may be necessary to retreat several times to eradicate the extensive underground root system.  Once applied, do not cut or roll the treated weed.  Allow the plant to wither and die completely before removing dead plant material.
