  • Usage

First comes the usage of the two chemicals.

Starting with tenacity, it is solely used to kill the unwanted weeds you often find among the grasses. The weeds create a hindrance for your grass to grow.

They act like parasites that would take all the nutrients out of the grasses in your lawn and make them rough, and sometimes even kill them.

In order to save your green grass from such kinds of unwanted weeds, tenacity would work best.

Now coming to Prodiamine, well, it does not kill unwanted weeds rather it stops their growth on the grass.

It also kills broadleaf grasses that would fight to survive with the beneficial grasses in the long run. So, to save the beneficial grasses, Prodiamine kills all the unwanted grasses.

  • Time to Spray

There is specific timing for the emergents to work efficiently on your grass. Randomly spraying would do no good if they are not sprayed at the right time to do their respective job of killing unwanted grass and weed.

For tenacity, early spring or fall is the best time for it to be effective on your grass. You just need to make sure that the soil temperature does not exceed 80 degrees.

Again, it depends on what purpose are you using it for. If used as a pre-emergent, it should be applied when the soil temperature is around 55 Fahrenheit. As a post-emergent, it should be applied when the grass is all grown up.

In the case of Prodiamine, it can be applied anytime you want before the weeds are grown. Fall can be a good season for applying as it can control the weed that would go on to grow in the Spring.

Just remember that the chemical or product needs to be applied before the grounds of your lawns are frozen or cold.

  • Area Coverage

There is a limitation when it comes to the area these products can cover.

You need to take perfect measurements of the chemicals and also know how much of it can you apply to how much length of the area.

For tenacity, you can expect it to cover about 1-2 acres of land with a mixture of 0.36 ounces per 1000 square feet.

As for Prodiamine, it cannot cover larger areas than tenacity can.

About 1 acre of land of grass can be covered by Prodiamine. It would need a mixture of 0.5 ounces for every 1000 square feet.

  • Emergent

As discussed before, emergents can be of two types. One is pre-emergent, which is used before the unwanted grass and weed are grown. Another is post-emergent, which is applied to kill the already grown weeds and control them.

Tenacity can be used in both ways as a pre-emergent and also as a post-emergent for killing and controlling the weed growth and also the growth of unwanted broadleaf grass.

On the other hand, Prodiamine works only as a pre-emergent for plants. It cannot kill unwanted weeds like tenacity but it can be used in controlling the birth and growth of them.

  • Effectiveness

The chemicals used as emergents for the plants do not start working right away. They will start working only after a certain period when they are ready to function.

The tenacity pre-emergent is a short-time application with its scheduled time. Whereas, Prodiamine pre-emergent has to go with a long-term plan for application and show results afterward.

Which Emergent Will Be the Best Fit for Your House?

Emergents are chemicals used in the grass of your lawns or gardens to prevent weeds or unwanted herbs to grow and damage the grass. They can be both pre and post according to the requirements of your lawn or garden grass.

Well, Tenacity works as both pre-emergent and post-emergent. So, you can get 2-in-1 service from it. But Prodiamine works better as a pre-emergent than Tenacity.

Apart from them being different in functionality, the chemicals are harmful when applied with bare hands. Excess of the chemical than the required account may result in damaging the grass in your yard and also your skin if you are holding it with your bare hands.

That is why keep in check how much of the product are you using and how much would be extra. Here is a complete overview of Tenacity for you.
