2. Ortho Weed B Gon Plus Crabgrass Control

Because of the dimethylamine salt composition, Ortho is leading in the weed killer market while Round-up is facing strong competition. Most of the Roundup weed killers are made of isopropylamine salt which is an isotope of glyphosate.

However, both are equally effective on the weeds in the gravel but there is a tiny difference in the mechanism of action.

The amount of the carbon molecule is present in Ortho which is more than in number in the case of Round-up. However, Round-up is having phosphorus which is absent in the Ortho.

This contradiction made Round-up the best weed killer in general but when it comes to the gravel Ortho beats roundup with its carbon molecular size.

“Compare -N -Save” is a brand that has used glyphosate directly to kill the weeds in the gravel.

The answer is they are using isotopic salt “isopropylamine salt” indirectly. They are combining it with excipients that are pharmaceutically inactive.

To avoid the formulation copyright they are using this diversion to make the product which is equally effective on weeds in gravel.

As they are using excipients with raw “isopropylamine salt“, you should use gloves and glassed while applying the formulation on gravel to kill the weeds.

The same discussion we have made earlier is applicable in this case. It’s the authentic formulation of the Round-up. Combining excipients with “isopropylamine salt” and making a weed killer is the standard operating procedure (SOP) of the Round-up.

The company says that the weed killer is rainproof for 30 minutes but when you applied it in our projects on “Nexturnagotech Limited” we saw that the information is more than authentic.

But We also experienced that the product does not work efficiently in every weather condition. It performs best in spring but in other seasons it can not perform with its full potential.

To identify the reason we used a grow tent setup where we can control the environment. After a longer period of time, we observed that this product does not work when the humidity level contradicts. Without a certain humidity level, the “isopropylamine salt” will not lose all of its electron sharing bonds thus it can perform with its full potential.

We all know that fluorine is a killer. In pools, we use fluorinated water to keep the germs away. I will recommend every mother use fluorinated water in her pool. But not in the kiddie pool. Keep the kids away from fluorine.

Ok let it go, where were we? We were in killing weeds.

So, Preen Extended Control Weed Preventer is one of the least choosing weed killers for gravel. But we recommend it as one of the best weed killers for gravel. 

Now why we do that, because the ingredient they use “Trifluralin” is composed of carbon, nitrogen, fluorine, hydrogen, and oxygen. That’s why I talked about fluorine. Fluorine can also be a good weed killer while it’s with carbon and nitrogen. However, it’s recommended that you may need a longer time to kill weeds with it.
