Killzall Weed & Grass Killer

Use this to kill all existing plant life within an area. 

1. How it Works 

KILLZALL Weed & Grass Killer is a non-selective, post-emergent herbicide designed to eliminate a wide range of unwanted vegetation, including broadleaf weeds, grasses, and other plants.  

The primary active ingredient, glyphosate, prevents the production of a protein crucial for photosynthesis, the process by which plants produce food. This essentially starves the plant internally. 

Once applied, KILLZALL is absorbed through the foliage and moves systemically throughout the plant, ensuring a comprehensive kill from the leaves down to the roots. 

2. Usage 

KILLZALL Weed & Grass Killer is used in areas where vegetation is not desired. Given its non-selective nature, care should be taken to avoid contact with desired plants. 

It’s essential to ensure thorough coverage of the unwanted plants for maximum effectiveness. Since KILLZALL acts fast, visible results, such as browning or wilting of the plants, can often be seen within hours to days of application. 

For best results, apply during warm, sunny weather when weeds and grasses are actively growing. Always follow label instructions regarding dosage, application methods, and safety precautions. Don’t apply on windy days. 

3. Targeting Specific Pests 

KILLZALL Weed & Grass Killer is designed to control a broad spectrum of weeds and grasses, like dandelions, clover, plantain, and more to more. Its non-selective formula ensures that virtually any plant it contacts will be affected. 

While KILLZALL is highly effective against many types of vegetation, some particularly resilient weeds or grasses might require a second application. Regular monitoring of the treated area and timely applications can help ensure a vegetation-free zone, whether it’s for creating a garden bed, clearing a pathway, or any other purpose. 

Note: When using KILLZALL Weed & Grass Killer or any herbicide, it’s essential to read and follow label instructions carefully. Protective equipment, such as gloves and goggles, should be worn during application. Keep the product out of reach of children and pets.
