How Does Spectracide Weed Killer Work

(Last Updated On: June 20, 2022)

The answer to how does spectracide weed killer work is both simple and complicated. The active ingredient in Spectracide weed killer is glyphosate, which is a broad-spectrum herbicide. That means it will kill most plants that it comes in contact with.

Glyphosate works by inhibiting an enzyme called EPSP synthase. EPSP synthase is involved in the synthesis of three amino acids: tyrosine, tryptophan, and phenylalanine. Without this enzyme, plants can’t produce these amino acids and they eventually die.

Spectracide weed killer is a popular choice for many homeowners because it is an effective way to kill weeds. But how does it work? The active ingredient in Spectracide weed killer is glyphosate, which is a herbicide that kills plants by inhibiting their ability to produce proteins.

This means that the weed is unable to grow or reproduce, and eventually dies. Glyphosate is a non-selective herbicide, which means that it will kill any plant that it comes into contact with, so it is important to be careful when using it.
