Differences Between Tenacity And Mesotrione
- Mode of Action
Tenacity is a pre-emergent herbicide.
A pre-emergent herbicide is used before the plants germinate.
The herbicide inhibits the enzyme that causes photosynthesis, stopping the weed from growing.
Once the weed is repressed, new healthy grass grows.
Mesotrione is a post emergent herbicide.
This herbicide will kill the selected plants and let the others survive.
Although the two herbicides contain the same active ingredients, they do not have the same efficiency. Tenacity is extreme. This is why it is sprayed before the plants start to grow.
The herbicide kills weeds within three weeks, and the dead weed starts to compose naturally.
Stubborn weed requires more than one treatment when using Tenacity herbicide.
Mesotrione is still as effective as Tenacity. Follow the manufacturer’s instructions when using this herbicide to ensure you achieve what it promises.
