Drexel MSMA 6 Plus HERBICIDE (2.5 Gallon JUG) - Targeted Post-Emergent

Our review of Drexel MSMA 6 Plus HERBICIDE focuses on its real-world performance for selective post-emergent weed control in managed turf and industrial settings. The product is aimed at groundskeepers and contractors who need effective suppression of both grassy and broadleaf weeds after emergence, and the single biggest reason to buy is its concentrated formulation that contains 6 pounds of MSMA per gallon for directed control in Cotton, golf courses, highway rights-of-way and sod farms. The reviewer found it practical for hot-weather applications up to 90F and valued the built-in surfactant for better leaf coverage.

Key Features

• Combination formula: The liquid combines herbicide and surfactant, improving spray coverage and uptake for tougher weeds.
• Post-emergent control: Designed to control both grassy and broadleaf weeds after they have emerged, reducing the need for repeated applications.
• High concentration: Contains 6 pounds of MSMA per gallon, providing strong active ingredient load for effective knockdown.
• Versatile labeled uses: Labeled for selective use in Cotton, golf courses, highway rights-of-way and sod farms where targeted control is required.
• Heat tolerance: Suitable for applications up to 90F, which helps maintain performance in warm conditions when many weeds are actively growing.

Who It's For

This product is best for professional applicators, turf managers and agricultural users who need a selective, post-emergent tool for areas like golf courses, sod farms, Cotton fields and highway rights-of-way. Its concentrated MSMA content and included surfactant make it suited to situations where directed control of listed grassy and broadleaf weeds is required rather than broad residential lawn use.

Homeowners and commercial lawn managers should look elsewhere because the product is no longer listed for use in residential or commercial lawns. If you need a general-purpose residential weed killer or a product approved for broad home lawn use, choose a label-approved alternative.

Pros & Cons

Pros

• Targets a wide range of listed weeds including barnyardgrass, crabgrass and nutsedge for focused control.

• High concentration of active ingredient provides strong post-emergent activity in labeled sites.

Cons

• Not registered for residential or commercial lawn use, limiting its suitability for typical homeowners.
