Prime Source Duo Stick (32 oz) by Primesource – Enhanced Coverage & Uptake for Herbicides

Overview

Prime Source Duo Stick combines organosilicone surfactants (OSS) with methylated soybean oils (MSO) to elevate the performance of compatible herbicides. This balanced blend is designed to deliver more thorough leaf wetting and deeper penetration than MSO alone, especially when applying at lower spray volumes. The result is a versatile additive for tank mixes that prioritize coverage and efficiency without changing the core herbicide chemistry.

Key benefits

• Increased efficacy of most pesticide applications through improved coverage
• Enhanced penetration of herbicides and fungicides for better target reach
• Improved nutrient availability at the root zone, supporting healthier root activity
• Faster availability of active ingredients, aiding timely uptake

Field-ready performance

In practical use, Duo Stick tends to provide more uniform distribution on leafy surfaces and better wetting at volumes below 15 gallons per acre. It works with MSO-based formulations while still leveraging OSS benefits, offering flexibility in tank mixes for diverse crops and conditions.

• Better coverage on hard-to-wet surfaces, reducing missed areas
• Consistent spray patterns at low-volume applications
• Compatibility with MSO-inclusive programs without sacrificing OSS advantages

Usage tips

To maximize potential while following best practices, consider these recommendations:

• Always follow the herbicide label for mixing order and compatibility
• Test new tank mixes on a small area before wider use
• Maintain agitation and monitor spray volumes to stay under 15 GPA for optimal wetting

Realistic expectations

Results depend on several factors, including crop canopy, weather, and spray equipment. Prime Source Duo Stick can help improve coverage, penetration, and uptake under typical field conditions. Benefits are described as possibilities rather than guarantees and should be evaluated within your specific context.
