This 32-ounce concentrate covers 16,000 square feet and kills over 200 weed types to the root — ideal for the standard suburban yard.

BioAdvanced hits the balance for homeowners with a quarter-acre or half-acre lot. Its 32 Fluid Ounce bottle covers 16,000 square feet, covering 16,000 square feet versus the Southern Ag Trimec’s 400 square feet for only a small jump in price. The active ingredients include Dicamba and Mecoprop-P, the same proven broadleaf-killing chemistry that targets dandelion taproots. Owners mention that one container did the whole front and back garden, confirming the coverage claim holds up in real use.

The brand claims it kills over 200 broadleaf lawn weeds, including dandelion, clover, and dollar weed, and it works on both southern and northern lawns. Unlike the Scotts EZ Feed Plus, which is a combined weed-and-feed product, this is a straight herbicide, so you get more weed-killing power per ounce without the fertilizer diluting it. Customers note it leaves Bermuda grass slightly brown for a bit, but the grass bounces back while the weeds stay dead.

One downside is the sprayer connection — multiple buyers mention that pressing the tab to activate the flow was frustrating on the first try. A few customers also found it less effective on nutgrass, so if your main issue is sedge, look elsewhere. For the typical dandelion-invaded lawn, this is the most balanced buy in the lineup.

You see dandelions curl up and die within hours with this ready-to-use trigger spray, and it kills over 250 weed types to the root.

When you want to see dandelions curl up and die the same day — not next week — Ortho Weed B Gon is the trigger to grab. This 24 Fluid Ounce ready-to-use formula covers 5,000 square feet, covering 5,000 square feet versus the Southern Ag Trimec’s 400 square feet, despite both being modestly sized bottles. The label claims results in hours and says it will not harm your lawn when used as directed. Reviews back that up: users consistently report great results killing clover and other weeds without killing the grass.

With a 4.3 out of 5 stars from 543 ratings, this is among the most trusted broadleaf killers on the market. It targets over 250 listed weed types. Unlike the Scotts EZ Feed Plus, which requires a hose-end attachment, the Ortho trigger bottle lets you spot-spray individual weeds precisely — great for protecting nearby flowers or garden beds.

The catch is the unit count: at 24.0 Fluid Ounces (24.00 Ounce), it runs out fast if you need to treat the whole lawn rather than spot-treat. Several reviewers suggest wearing gloves and a mask as a precaution due to the chemical concentration. For quick, visible action on dandelions without mixing or measuring, this is the sprayer to keep in the garage.

This hose-end spray kills dandelions and feeds your lawn in one pass, covering 4,000 to 6,000 square feet per bottle.

If you want to simplify your lawn care routine, this Scotts product handles two jobs at once. The EZ Feed Plus Weed Control both fertilizes your lawn and kills broadleaf weeds like dandelion, clover, and ground ivy in a single application. You attach the 32 Fluid Ounce container to a garden hose and spray evenly. It provides coverage of 6,000 sq ft on warm-season lawns and 4,000 sq ft on cool-season lawns — note the split so you choose the right setting for your turf type. Reviewers point out that weeds begin to curl up within a few days, with hard-to-control weeds sometimes needing another application in 3 to 4 weeks.

At 33.28 Ounces, this is the heaviest bottle in the ready-to-spray category at 33.28 ounces versus the 16 ounce Southern Ag Trimec, which reinforces that you are getting both herbicide and fertilizer in the same container. The mixing ratio is 25:0:2, which is the N-P-K (nitrogen-phosphorus-potassium) fertilizer ratio. Reviewers confirm it is effective against clover and creeping sedge that cheaper brands do not touch, and it gives grass a growth boost alongside weed control.

The biggest frustration in the reviews is the connection: a few shoppers say the liquid did not come out because the cap was missing or it leaked at the hose connection. If you get a sealed, correct unit, it works. The product is also reported as discontinued by Scotts according to one customer service response, so stock may be limited. For the homeowner who wants to feed and kill weeds in one pass, this is a convenient choice — if you can find it.

Spray this on individual dandelions and pull the whole root out by hand a week later without any tool.

For the gardener who patrols the lawn with a spray bottle, this Scotts TouchUp is built for spot-treating single weeds. The 24.0 Fluid Ounce ready-to-use spray kills dandelion, clover, and crabgrass without harming the surrounding grass. One reviewer describes the process: the weed wilts, dies, and a week or so later you pull up the whole weed, root and all, with no tool — and that dandelion does not come back the next year. It also got strong marks for tackling Canada thistle in a seriously neglected lawn.

The bottle is small and convenient. One reviewer with a 3,500 sq ft lawn buys one spray bottle per year for dandelions only. It is lighter than the BioAdvanced concentrate at 24.96 Ounces versus 32 Ounces, and the ready-to-use format means zero setup. Unlike the PBI/GORDON Trimec gallon, this is not for blanket coverage — it is your precision tool for the weeds that pop up here and there.

The main criticism from negative reviews is that a minority of users saw no effect at all — the weed did not even turn brown, and new flowers appeared after the second spray. That could be a batch issue or user error with timing (rain shortly after application washes it off). It is also expensive per square foot compared to concentrates. For the patient spot-treater who does not mind waiting a week to pull dead weeds, this is an effective option.

This 16-ounce bottle of Trimec concentrate covers only 400 square feet, but it is the cheapest way to get proven root-killing chemistry for a tiny lawn.

If you have a small patch of lawn or just want to test a Trimec-based product without committing to a gallon, this Southern Ag 16-ounce concentrate is your low-risk entry point. At 16 Fluid Ounces, it covers only 400 square feet covering 400 square feet versus the BioAdvanced Weed Killer’s 16,000 square feet. The active ingredients are Dicamba, Herbicide, and Trimec with a surfactant (a sticking agent that helps the spray cling to weed leaves), giving you the same potent chemistry as the larger jugs. One buyer mentioned it killed a dandelion invasion in 2 weeks with no harm to the lawn, with about 10% of weeds needing a respray.

The 16 Ounce weight is the lightest of all six products. It is designed for use on 9 turf types and works with conventional and hose-end sprayers. For the budget-conscious shopper who needs to clean up a small area, this is a practical way to get Trimec-level results without the price or volume of larger bottles.

However, multiple reviews point out that while this product knocks weeds down fast initially, they tend to come back relatively quickly, requiring reapplication every few weeks. It is not great with clover according to some, and it lacks the staying power of larger concentrates. For the shopper with a small dandelion problem and a small yard, this works well.
