Killzall Weed and Grass Killer
Killzall Weed and Grass Killer is a herbicide commonly used to control unwanted vegetation.

Killzall Weed and Grass Killer contain glyphosate, a non-selective herbicide that can kill many plants.
- Killzall is a liquid weed killer with a double-surfactant formulation designed to dry quickly on the plant and begin working quickly.
- One 32-ounce bottle can treat up to 6,400 square feet.
- It can also be used for brush or vine control on green and actively growing plants.

Both Killzall and Roundup are post-emergent, non-selective herbicides that are potent against various weeds and grasses. They are available in liquid concentrates that must be mixed with water before application.
Killzall has a higher concentration of the active ingredient, glyphosate, at 41%, while Roundup contains 18% glyphosate and an additional 0.73% diquat, another effective herbicidal compound.
A vital characteristic of these herbicides is that they are rain-fast, meaning they retain their effectiveness even after rainfall.
This property distinguishes them as highly reliable in unpredictable weather conditions. Killzall becomes rain-fast in 2 hours, while Roundup achieves this feat in a shorter span of 30 minutes.
Versatility in Use
Both products are engineered for use in various locations, including around trees and shrubs, on patios, driveways, walkways, and fences, and even in gravel areas and mulch beds.
Their effectiveness extends to larger jobs like lawn replacements or garden plot preparation, further showcasing their versatility.
Efficacy & Action Speed
While both products guarantee to kill weeds and grasses down to the root, their speed of action is a noteworthy difference. Roundup includes FastAct Technology, which ensures visible results in as fast as 9-12 hours.
In contrast, Killzall does not specify a timeframe for visible results. Despite this, both products ensure the complete elimination of unwanted vegetation.
The dosage requirements for each product differ. Killzall recommends using 2.5 to 5 tablespoons per gallon of water, whereas Roundup suggests a slightly higher volume with 6 fluid ounces per gallon of water.
This indicates that although Killzall has a higher concentration of glyphosate, more Roundup is needed per gallon of water to achieve the desired results.
Killzall boasts a double-surfactant formulation. This feature enhances the product’s ability to stick to and penetrate plants more effectively, resulting in thorough weed elimination.
On the other hand, Roundup promises to kill the toughest weeds and grasses to the root, reinforcing its reputation as a highly effective herbicide.
Both Killzall and Roundup exhibit robust characteristics as non-selective, post-emergent herbicides. While Killzall has a higher glyphosate concentration, Roundup compensates with an additional compound, diquat, and FastAct Technology that offers visible results in just 9-12 hours.
Roundup also boasts a quicker rain-fast property, effective just 30 minutes after application, as compared to Killzall’s 2 hours. Yet, Killzall’s double-surfactant formulation promises more effective plant penetration for weed elimination. Dosage recommendations suggest more Roundup is needed per gallon of water, perhaps due to its lower glyphosate concentration.
Although both products are versatile and highly effective, Roundup’s faster action speed and rain-fast time offer an edge, particularly in areas with unpredictable weather conditions and for those seeking quick results.
Therefore, Roundup might be considered the better option, balancing efficiency and speedy action. However, the choice should depend on the specific needs and conditions of the user.
