Ortho WeedClear Weed Killer for Lawns Ready-To-Spray is a convenient, liquid herbicide designed to target and eliminate over 250 common lawn weeds like dandelions, clover, and poison ivy without harming the grass when used as directed. This product is suitable for large lawns, covering up to 16,000 square feet with a 32-ounce bottle. The mode of action involves ingredients that kill weeds down to the root, and users can expect visible results within hours of application.

Additionally, it becomes rainproof within an hour of drying, ensuring it remains effective even after unexpected weather changes. This formulation is also relatively safe for humans and pets as they can re-enter the treated area once the spray has dried. A notable advantage is its ease of use; by simply attaching the garden hose to the sprayer, the application process is straightforward and quick.

Users need to carefully follow the directions to prevent potential harm to desirable plants. This product is an ideal choice for homeowners with large lawns looking for an efficient solution to manage a wide range of weeds without damaging their grass.

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.
