However, this product is specifically suited for non-lawn areas like driveways, sidewalks, patios, and gravel areas, meaning it should be kept away from desired plants and grass.

Additionally, there's a notable environmental impact due to its potent formula. For those looking for ease of use and long-lasting weed control, this product is a robust choice, but it's crucial to handle it with care to avoid unintended damage to surrounding plants.

BioAdvanced Brush Killer Plus is a concentrated liquid herbicide designed to target tough brush and over 75 types of weeds, including poison ivy and poison oak. It uses triclopyr as its active ingredient, which works by penetrating deep into roots and vines, ensuring effective long-term control rather than just surface wilting. The product starts showing visible results within 1 to 6 weeks, so patience is needed after application. It’s rainproof after just 4 hours, which means it can withstand light rain fairly quickly, making timing less stressful.

This herbicide is best used on actively growing weeds and brush over a sizable area (up to 4,000 square feet per 32 oz bottle), making it practical for medium to large lawns or properties with persistent invasive plants. As a concentrate, it requires mixing before use, which allows flexibility in how strong the application is but adds a small step compared to ready-to-use sprays.

Triclopyr can also affect desirable plants if not carefully applied, so precision is important to protect your lawn or garden. Users should follow label instructions carefully to minimize risks. This herbicide is a solid choice for those dealing with stubborn brush and broadleaf weeds like poison ivy, especially if you want a product that provides thorough root control. However, it demands careful application and some wait time to see full effects.

Additionally, it feeds your lawn, promoting quick greening and sustained growth for up to 3 months. One bag covers up to 10,000 square feet, making it suitable for larger lawns. However, it's important to note that this product is not available for sale in New York, Hawaii, and Florida due to regulatory restrictions.

The multifunctional approach of this product is convenient, but it may not be as effective on every lawn type, and some users have reported mixed results. The ease of application and combination of weed control with fertilization is a significant time-saver. Remember to follow the usage directions carefully to avoid harming your lawn.
