However it is resistant to some groups of herbicides. It is resistant to some sulfonylurea herbicides, including chlorsulfuron eg Glean used in cereals and metsulfuron eg Escort used for general weed control, so a second herbicide often needs to be applied to allow for this.
It is not controlled by trifluralin so can be a problem in crops using this herbicide. Black nightshade often builds up in orchards, which can be due to resistance developing to triazine herbicides like simazine when they are used season after season, and it is also hard to kill with glyphosate once it grows up into lower branches of trees. Although the development of resistance by black nightshade to triazine herbicides was suspected for many years, in research at Massey University we confirmed that black nightshade taken from an arable cropping paddock in Manawatu was resistant to triazine herbicides used in peas and maize such as cyanazine, terbuthylazine and atrazine.
The resistant plants tolerated over 30 times higher rates of herbicide than ordinary black nightshade. Recut and reapply in the same way in two weeks, then repeat as necessary. Cut nightshade back to the ground, and remove the sprouts until the vine no longer returns. This could take several years. Alternatively, cover the area -- plus an extra 6 to 12 inches on all sides -- with a thick black plastic or woven plastic fabric and secure it with bricks, rocks or stakes. Leave the plastic in place for two years, ensuring that the nightshade does not creep through any holes or along the sides.
Lay more plastic as necessary for effective control. Melissa Lewis is a former elementary classroom teacher and media specialist. She has also written for various online publications. Up vote: but I would add that if the quantity is large enough then it would probobly be safer for you to use an herbicide like glyphosate and use gloves!
Also, be sure to make as many of your neighbors and those who live in close proximity to you aware of the fact that you found Nightshade growing naturally on your property. Add a comment. Personally I would pick up the plant and dispose it as garbage. Between nightshade and glyphosate, what is the most dangerous?
I think the second one. Additionally I would not burn such plant. I think it could release in the air the active drugs. Giacomo Catenazzi Giacomo Catenazzi Deadly Nightshade is, without a doubt more dangerous then glyphosate - it kills - yes, kills, far more people then Glyphosate. While glyphosate may or may not have significant negative affects if applied as directed depending on who you ask, by any reasonable measure its safer for animals and plants it does not directly touch.
BTW it is not so dangerous as many other wild and many garden plants. In any case I would for sure not use glyphosate for weeks, near kids. A regular use could make the impression to kids that it is not dangerous, so if you forgot to lock it, they could do stupid things with it.
According to slate. According to thepoisongarden. Is one of you thinking of black nightshade instead of deadly nightshade? Colin Beckingham Colin Beckingham Sign up or log in Sign up using Google.

I'm worried that my kids will be poisoned. A: The nightshade you describe solanum dulcamara is not actually very dangerous, but it is mildly toxic.
The red berries that form after the flowers die are the most toxic part, especially when they're still green. They contain a substance called solanine, which can cause nausea, vomiting and diarrhea if eaten. Solanum dulcamara is known by a number of common names, including deadly nightshade, bitter nightshade, bittersweet nightshade and climbing nightshade.
