BioAdvanced Extended Control Brush Killer, Ready-to-Use 1.3 Gallon

In this review the BioAdvanced Extended Control Brush Killer is evaluated for homeowners and property managers who need long-lasting control of tough woody brush. The bottom line: it targets roots and promises up to 12 months of protection, making it a sensible choice when longer-term suppression of Poison Ivy, Poison Oak, blackberry, kudzu, bamboo and other listed brush is the priority. Our review highlights that it is easy to apply from the ready-to-use 1.3 gallon bottle and produces visible symptoms within days for many users, though instant results are not guaranteed.

Key Features

• Long lasting control: Provides up to 12 months of protection, reducing the need for frequent reapplications across a full season.
• Root-killing action: Systemic formula targets the root to prevent resprouting of persistent brush such as kudzu and blackberry.
• Fast visual results: Wilting and yellowing can appear within 1 to 28 days, so users can see progress without waiting months.
• Rainproof in hours: Becomes rainproof in about 4 hours, allowing treatment to hold after light rain and improving reliability.
• Ready-to-use capacity: The 1.3 gallon bottle treats up to 650 square feet and eliminates mixing for faster application.

Who It's For

This product is aimed at homeowners, small acreage owners and groundskeepers who need a ready-to-use brush killer that treats tough, woody species and offers extended control through a full year. It suits sites where follow-up applications are inconvenient and where systemic root control matters more than instant cosmetic results.

It is less well suited to users who expect overnight dieback or who require a lower-cost short-term spot treatment; some customers also reported issues with pump strength or leakage, so professionals who expect heavy daily use may prefer commercial concentrate applicators and replacement pumps.

Pros & Cons

Pros

• Long-lasting protection up to 12 months reduces frequency of retreatment.
