What is Systemic weedkiller/Herbicide ?
We know that farming started 8000 year ago, even at that time some unwanted plant used to grow in our field which we know as weed .
Weed cause a lot of harm to our main plant as they absorb the manure and fertilizer form the main plant and hence they do not even allow sunlight to reach the main plant and hence they do not under go photosynthesis. and our plant wither. Even at this time, people used to remove weed from their fields but herbicides had not been discovered at that time. herbicide were discover during the second world war. It is divided into two type base on mobility. first systemic herbicide and second contact herbicide. systemic herbicide are mobile in the plant/ species.
Definition
Systemic herbicide are mobile in the weed and when the come in contact with any part of weed, they destroy all part of weed.

How to work Systemic weedkiller/Herbicide?
When we spray systemic weedkiller/herbicide it reaches inner part of the Weed, that means, When we spray systemic herbicide on the leaf of the Weed, it reaches leaf, stem, root and all part of plant and destroy entire selected of weed or try to destroy.
Selective systemic weedkiller/herbicide
Herbicide that penetrate the system of a selected weed to stop it growth or try to kill the weed/species, is called selective systemic Weedkiller/herbicide. selective systemic herbicide used to kill weed in the field.
Ex- 2,4D etc.
None Selective systemic weedkiller/herbicide
herbicide which penetrate into the system of all type of weeds and kill that weeds . it is not any contain selective weed. it is called none selective systemic herbicide. none selective systemic weedkiller/herbicide often used to kill weed roadside, canals meadows, and backyard etc.
Ex- Glyphosate, paraquat etc.
Narrow spectrum systemic weedkiller/herbicide
Herbicide that kill narrow leaf by penetrating inside them, it is called narrow spectrum Systemic weedkiller/herbicide.
Ex- Penicillin etc.
Broad spectrum systemic weedkiller/herbicide
Herbicide that kill broad leaf by penetrating in side them it is called broad spectrum systemic weedkiller/herbicide.
Ex- 2,4DÂ etc.
Advantage of systemic weedkiller/herbicide
(i) This herbicide kill by entering the system , which kill the weed from its roots.
(ii) Even it if 2 or 3 hours after spraying the systemic herbicide, the systemic weedkiller/herbicide will not still reduce the effect of herbicide because by then it has spread through out the weed’s system.
(iii) Systemic Herbicides save our time to a great extent.
(iv) It take less effort to spray systemic herbicide.
