Scotts WeedEx weed preventer can prevent more weeds and grass from all types of lawn in spring and fall. On the other hand, Scotts Halts Weed Preventer can prevent only crabgrass in spring and poa annua, henbit, and chickweed winter grass in the fall.
Wouldn’t you want to walk on a fresh lawn all year round? But weeds can spread pretty fast, making the lawn bushy and unattractive. That’s why applying weed prevention at least twice a year is a must.
In this article, I’ll discuss two weed preventers and show you the best solution.

Key Differences Between WeedEx and Halts Weed Preventer
- Features
Scotts WeedEx Prevent With Halts can prevent crabgrass and problem weeds all year.
In fact, it stops crabgrass even before it starts.
After applying it on your lawn, you will get effective pre-emergent control of crabgrass, foxtail, spurge, oxalis, and other grassy and broadleaf weeds.
On the other hand, Scotts Halts Crabgrass and Grassy Weed Preventer protect your lawn from weed invasion.
One application in a year will keep your lawn free from crabgrass all season long. Most importantly, the product’s performance won’t be affected by rain, snow, or freezing weather after application.
- Ingredients
The main active ingredient of WeedEx and Halts is Pendimethalin, consisting of 1.71% of the entire formula for both products. The rest of it consists of other necessary components. Pendimethalin is a selective herbicide of the dinitroaniline class.
That means it does not kill all the plants that come in touch with it; instead, it kills targeted plants. It’s primarily used as an herbicide that destroys and prevents the growth of certain plants like grasses and weeds. People mainly use it on lawns and crops.
- When To Apply
Application time is similar for both herbicides. You must apply them twice a year to get a yearlong weed-free lawn. You have to apply WeedEx and Halts in Early spring to get a fresh lawn for the entire season.
Then you have to apply it again in the fall to have weed-free and crabgrass-free for the whole winter. For southern California, apply them before March 1st; in northern California, apply them before mid-march.
There are three ways you can apply them. You can spread them using a rotary spreader with a 2¼ setting, a drop spreader with a 4½ setting, or a wiz spreader with a 3 ¼ setting.
- Applicable To
You can use both herbicides in almost all types of lawns.
However, WeedEx can prevent more weeds and problem grasses compared to Halts.
With WeedEx you can protect your lawn from crabgrass, foxtail, spurge, barnyard grass, fall panicum, goose grass, oxalis, etc., in the spring.
And in the fall, it can prevent moss, henbit, chickweed, poa annua, corn speedwell, and other winter weeds from your lawn.
In contrast to WeedEx, the Halts weed preventer only prevents crabgrass all season and winter weeds like poa annua, henbit, and chickweed. It also prevents moss in the fall.
- Coverage Area
There is no difference in coverage area between the two solutions. Both the herbicides can cover up to 5,000 square foot area per 10 pounds of the products. And these herbicides are packaged as 10 pounds bags.
- Price
There are a couple of dollar differences between WeedEx and Halts weed preventer. You will have to spend $23.99 for 10 pounds of WeedEx.
On the other hand, 10 pounds of Scotts Halts will cost you $26.49. However, both are available in many online stores with lower price tags.
Which Weed Preventer Will Be Best For You?
I’m sure you have caught more similarities than differences between these two products, and it can be tough to pick up the right one. Well, both these herbicides are pretty good in action, to be honest.
But I would suggest you go for WeedEx weed preventer. It can effectively prevent crabgrass before it starts growing. Besides, you can prevent more types of grasses with this product.

Final Thoughts
I’ve found very few differences between WeedEX and Halts weed preventers. So, you can pick the one you find first. However, my suggestion would be the WeedEx. Not that it goes out of the way and works better than its counterpart.
But you’ll be able to protect your grass from more types of weeds, that’s it. Additionally, it’s cheaper so you’ll have to spend less money on maintaining your lawn.
I live in SC . Scotts rep. told me not to apply Weed EX to a dormant lawn. I would like to know if this is the same with Scotts Halts Crabgrass & Grassy Weed Preventer. I mulch my leaves with mower in the Fall but I am running into a problem as the leaves are still on the trees in November .
Ralph,
Scotts WeedEX and Halts are good for pre-emergent crab grass, but what about post-emergence?
Do I have to use Round up to destroy the entire lawn to get rid of several pockets of crabgrass and then reseed?
I don’t see the point in fixing spots because the new seed will not match the rest of the lawn.
David
I still don’t get it. Two products with the same ingredient but different prices. Why does one prevent more weeds than the other. Your article suggests there is a difference but does not say what the difference is.
