I'm surprised to see trichlopyr doesn't give better results. Especially since dicamba and 2-4D do. Could it be an artifact of application rate?

Hello, do any butterflies use it as host plant?

I agree triclopyr should work on this plant. I don't know the background for that rating - someone might have used an amine formulation (ester would give much better penetration of the tough leaf cuticles), or the chemical could have been applied too late in the season. Papers from Australia and the middle east suggest that mixtures of triclopyr with other systemic herbicides, or multiple-year applications of triclopyr, are more effective, so it seems like other places have trouble too.

Sphinx & hawkeye moths will use silver nightshade. I like the moths, but their caterpillars tend to feed on tomatoes (tomato hornworms). Bumblebees will also use this plant.
