What are the advantages of weed killers?

Answer 1

Kills weeds, obviously. Most herbicides that are sold to gardeners are non-specific herbicides--in other words, the chemical solution in the jug or bottle will kill any plant that comes in contact to the chemical, no matter if it's a plant you don't consider a weed or not. It also means that it doesn't target specific types of plants (like broad-leaved plants and/or grasses), but a wide variety.

How herbicides work depends on what type you are using. There are two different types; contact herbicides and systemic herbicides, both kill plants in the same basic way they either stop the plant from "breathing" or "eating". Contact ones hit the plant and kill whatever is growing above ground and systemic herbicides get sucked in by the plant, travel down to the roots and kill the plant from there.

Answer 2

By contact, drenches, or drift or systemically is the way that weed killers kill houseplants. Intentional applications of herbicides may kill houseplants through applications on the surfaces of leaves or through injections or intakes of drenches in the soil. Unintentional treatments result when doors and windows are left open or when houseplants are aired on balconies, decks, patios, porches, or verandas during nice weather and receive droplets drifted by the wind from treatments of other vegetation elsewhere on the property.

Answer 3

It kills their roots.

Answer 2

Not necessarily their roots. Some weedkillers (paraquat, for example) just kill the green parts of plants. Obviously the roots may die in the process but only because the whole plant has died.

Answer #3

Both answers are technically right but are missing some information that should have been included. Herbicides (weed killers) can work in two different ways. 1 The herbicide touches any part of a plant that is above ground and kills that part of the plant but the roots may still live.

2 A herbicide is sprayed and the plant sucks it in (just like it would water) and the herbicide travels through the plant reaching the roots and then kills the plant from there.

That is just a basic answer and doesn't discuss things like soil sterilents or other ways of controlling plant growth. I hope that this was helpful.

Answer 4

The effect of weed killer for the area depends upon the type of ecosystem, herbicide, and weather. A weed killer that is contact, non-residual, target-specific has little impact other than upon the weed to be eliminated. A weed killer that is residual and non-target will impact the immediate vegetation.

Answer 5

Accelerating or sabotaging growth and disrupting life-sustaining activities are the ways that weed killers work to kill weeds. Weed killers typically designate herbicides whose ingredients are either laboratory- or Mother Nature-made. They may be contact or systemic, non-residual or residual, non-specific or target, organic or synthetic.

Answer 6

Eliminating the perceived nuisance plant, getting the job done quickly and making room for desirable plantings are advantages of using weed killers. Manual removal contrastingly is not only generally more time-consuming than herbicide schedules but also often ineffective. It remains almost impossible -- other than by combining any two of controlled burns, extreme cuts, herbicide treatments, manual or mechanical removal and solarization -- to remove all of the plant's germinating parts from under an area's ground-surface level.

The best times of year to apply Scotts Weed & Feed are spring and fall. Daytime temperatures should be consistently higher than 60 degrees and lower than 90 degrees.
