Know before you buy
No, this is a non-selective herbicide, meaning it will kill any plant it touches, including your flowers and vegetables. It is intended strictly for non-crop areas like driveways, fence rows, and bare ground where you want to prevent all plant growth.
While the product begins working immediately upon contact, you will typically see visible wilting and browning of weeds within a few days. The product continues to work systemically to kill the root, ensuring the weeds do not return.
Yes, Hi-Yield Killzall 365 provides residual control for up to 52 weeks. However, the actual duration can vary based on soil type, rainfall, and the specific weed species present in your area.
You should exercise extreme caution. Because this product has long-lasting residual activity, it can be absorbed by the root systems of nearby trees or shrubs if applied within their root zone, potentially causing damage or death to those plants.
You can use standard hand-operated pump sprayers for smaller areas or mounted spray equipment for larger spaces. Always ensure your equipment is thoroughly cleaned after use to prevent accidental damage to desirable plants during future applications.
Yes, this formula is specifically designed to handle stubborn vegetation, including poison ivy, brush, and vines. It is a powerful, total vegetation control solution that reaches deep into the root system to ensure these tough plants are eliminated.
