06/19/2025

Sometimes you don’t just want to knock down weeds—you want to wipe the slate clean. Whether you’re managing fencelines, industrial yards, railways, or gravel lots, selective spot treatments won’t cut it. That’s where total vegetation control herbicides step in, and two of the most trusted options on the market are Topsite G Herbicide and Transformer 5G Herbicide. industrial, commercial, and non-cropland areas

Only to be used in industrial, commercial, and non-cropland areas…Let’s break down what makes each one a powerhouse and how they’re best used.

Topsite 2.5G Herbicide – Granular Simplicity, Long-Term Control

If you’re looking for a low-maintenance, long-acting solution, Topsite 2.5G is the one. This granular herbicide contains Imazapyr, a powerful, non-selective ingredient that eliminates existing vegetation and prevents future growth for up to a year with a single application.

? Why Professionals Choose Topsite G:

Ready-to-Use Granules: No mixing, no sprayers—just apply directly from the container or with a handheld spreader.
Long Residual Control: Keeps areas clear of vegetation for up to 12 months.
Ideal for Bare Ground Applications: Perfect for fencelines, utility poles, storage areas, parking lots, and more.

⚠️ Use Carefully:

Since Imazapyr has long-lasting soil activity, keep this away from desirable plants and avoid areas with water runoff. It’s designed to leave absolutely nothing behind.

Transformer 5G® – Aggressive Control in Granular Form

Need the strongest stuff in the shed? Meet Transformer 5G®. This granular herbicide is formulated for industrial-strength, bare-ground control using Tebuthiuron—a heavy-hitter when it comes to both pre- and post-emergent weed and brush control.

? What Makes Transformer 5G® Special:

Kills Existing Growth + Prevents Regrowth: It targets roots and prevents germination, making it a dual-action performer.
Up to a Year of Control: A single treatment can keep the area vegetation-free for 12 months or longer, depending on soil and rainfall.
Granular Ease, Industrial Power: Granular format simplifies application, but the potency is serious—best for places like railroads, rights-of-way, storage yards, and fence lines.

? Pro Tip:

Apply before rainfall for best root zone absorption. Like Topsite 2.5G, it moves through the soil, so keep it away from anything you want to keep green.
