Control marestail / horsetail with SBK and KPlus+

If you want to control marestail / horsetail we are currently advising that you use SBK with K-Plus. 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 all parts of the plant as some underground rhizomes go into a dormant phase in a very mature, thick colony and will only product leaf when the first cover of shoots have have been controlled
