Silverleaf Nightshade

Has anyone found a suitable herbacide for this silver leaf nightshade?

I have tried glyphosphate with a surfactant but with little results. I have heard of a product called percloran(?) but don't know if it's effective or if I have the correct name.

So far I've been removing this stuff by hand, but it keeps coming back.

A few of my sheep have become very ill after eating these weeds, and it has cost me a bundle in veterinary costs.

Does anybody have any advice on getting rid of this type of nightshade?

This is not one I've personally had to deal with. But I do sympathise.

Silver leaf nightshade is deep rooted, and spreads not just by seed but by creeping rhizomes AND by root fragments too! Which is why it's coming back after hand removal - it only takes a tiny piece of root for regrowth.

You're right that the berries are definitely poisonous to livestock, but the spines should put them off a bit (dozy sheep!).

Glyphosphate should work well - but it's apparently best applied when the berries are green to yellow. And when the plants are not water stressed (better take-up).

Hopefully someone with more direct experience can add to this.
