Sycamore Seedlings

Many paddock owners realise how important it is to control sycamore seedlings if they are grazed by horses and ponies.  Some seedlings contain the toxin hypoglycin A and ingestion can cause a potentially fatal condition called equine atypical myopathy.  Although not on the label, Grazon Pro will give good control of these seedlings.  Please note any extended grazing intervals if controlling poisonous weeds.

Grazon Pro Weed Killer also gives strong control on the following:

Annual weeds
Black Bindweed, Black nightshade, Chickweed, Cleavers, Cranesbill, Dead-nettles, Fat-hen, Field bindweed, Forget-me-not, Medick, Pale Persicaria, Scarlet pimpernel, Self-heal, Small nettle - plus more
