BioAdvanced Brush Killer Plus, Concentrate Weed Killer, 32 oz – Kills Tough Brush Roots & Poison Ivy

Rating
8.2
Type of Herbicide
Mode of Action
Application Timing

Most important from
4651 reviews

Type of Herbicide
Effectively eliminates tough brush like poison ivy and stubborn vines, ensuring long-term control rather than just surface wilting.
Mode of Action
Visible results take time, often around two weeks, requiring patience after application for full effectiveness.
Application Timing
Rainproof within four hours, allowing for flexible timing and less worry about light rain after spraying.
Formulation
Application method greatly influences success—directly applying undiluted product to cut stems prevents regrowth better than foliar spraying alone.
Safety and Environmental Impact
Requires careful and precise application to avoid damaging desirable plants, making attention to detail essential.

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.

Roundup For Lawns₂ Concentrate is a liquid herbicide designed specifically for Northern grasses, targeting a wide range of weeds—253 types, to be exact, including stubborn ones like crabgrass, dandelion, and poison ivy. This product is particularly useful for lawns with Kentucky Bluegrass, Perennial Ryegrass, and various types of Fescue, ensuring compatibility with these specific grass types. One of its key strengths is its rapid action; it starts working immediately and becomes rainproof in just 3 hours, meaning that users won’t have to worry about weather conditions shortly after application.

However, the need to mix could be a downside for those seeking a ready-to-use solution. While effective, users must follow the instructions carefully to avoid damaging the lawn, as it targets weeds down to the roots.

On the environmental front, it's essential to keep in mind that like many herbicides, there are safety considerations that must be adhered to, especially around children and pets. Roundup For Lawns₂ Concentrate is a powerful ally against common lawn weeds, best suited for those willing to invest in careful application for robust lawn maintenance.

Buying Guide for the Best Herbicides For Lawns

Choosing the right herbicide for your lawn is crucial to maintaining a healthy and beautiful outdoor space. Herbicides are chemicals used to control unwanted plants, commonly known as weeds. When selecting a herbicide, it's important to consider the type of weeds you are dealing with, the type of grass you have, and the environmental impact. Understanding the key specifications of herbicides will help you make an informed decision that best suits your lawn care needs.
Type of HerbicideHerbicides can be classified into two main types: selective and non-selective. Selective herbicides target specific types of weeds while leaving your grass unharmed, making them ideal for lawns. Non-selective herbicides kill all vegetation they come into contact with, which is useful for clearing areas but not suitable for lawns. To pick the right one, identify the weeds in your lawn and choose a selective herbicide that targets those specific weeds.
Mode of ActionThe mode of action refers to how the herbicide affects the weeds. Systemic herbicides are absorbed by the plant and move throughout its tissues, killing it from the inside out. Contact herbicides only affect the parts of the plant they touch, requiring thorough application. Systemic herbicides are generally more effective for perennial weeds, while contact herbicides work well for annual weeds. Consider the type of weeds in your lawn to determine which mode of action is best for you.
Application TimingThe timing of herbicide application is crucial for its effectiveness. Pre-emergent herbicides are applied before the weeds germinate and are effective in preventing weed growth. Post-emergent herbicides are used after the weeds have already appeared and are effective in controlling existing weeds. If you are dealing with a weed problem that has already emerged, choose a post-emergent herbicide. For preventive measures, opt for a pre-emergent herbicide.
FormulationHerbicides come in various formulations, including liquid concentrates, ready-to-use sprays, and granular forms. Liquid concentrates require mixing with water and are suitable for large areas, while ready-to-use sprays are convenient for spot treatments. Granular herbicides are spread over the lawn and activated by watering. Consider the size of your lawn and the ease of application when choosing the formulation that best fits your needs.
Safety and Environmental ImpactSafety and environmental impact are important factors to consider when choosing a herbicide. Some herbicides can be harmful to pets, children, and beneficial insects. Look for products that are labeled as safe for use around pets and children and have minimal environmental impact. Organic and natural herbicides are available and can be a safer alternative. Assess your lawn's usage and choose a herbicide that aligns with your safety and environmental concerns.
