can anyone tell me what is systemic herbicide? are they the best way to control weeds?

Question

systemic herbicide

Answer 1

Systemic refers to entering the plant through the root and spreading throughout the plant. Usually about insecticides. Roundup kills weeds very effectively

Answer 2

Hi, A systemic herbicide are chemicals that work throught the root sytem of the weeds. It is drawn up to kill them like fertilizer and it kills them in a few days. I have never used them because I have always used weed killer that kills them on top through a spreader. I would think you would have more success with this type of herbicde, because it is not washed off like chemicals that are laying on top and get washed off from rain or from walking the grass. Hope this answers your question, John

Answer 3

"Systemic" is the way the poison circulates through the plant - taken up through the roots and into the whole "system" (thus, systemic) of the plant. It is not selective and will kill anything that takes the poison up. Round-Up or some other broad-spectrum weed killer is pretty much effective on just about anything you want to kill. If you want to control weeds before they germinate and sprout, try some of the granulated controls like Preen.
