TECHNOTE
WEEDMASTER ARGO THE DUAL SALT KNOCKDOWN SPECIALIST Nufarm’s high performance weedmaster® ARGO® sets a new standard for convenient and effective knockdown control. A 540g/L Dual Salt Technology® glyphosate, weedmaster ARGO delivers powerful, broad spectrum weed control and is an ideal partner as part of a complete spray program at knockdown.
surfactant package, Dual Salt Technology allows for a higher active loading and accelerates plant uptake as the glyphosate passes through the cuticle into the plant sap transport more quickly. Dual Salt Technology also provides improved compatibility over single salt glyphosates, better mixing in hard water and fast brownout on a wide range of weeds. RAPID UPTAKE A key feature of weedmaster ARGO is its rapid uptake by weeds and fast brownout.
HOW DUAL SALT TECHNOLOGY WORKS Dual Salt Technology was developed in Australia by Nufarm and is a key component of weedmaster ARGO and the weedmaster range. Unlike many other glyphosates, weedmaster ARGO is formulated using two bases to form an advance glyphosate formulation. Combined with a tailored
Dual Salt Technology and the tailored surfactant package in weedmaster ARGO work in tandem to deliver rapid translocation within the plant, providing fast control on a wide variety of weeds. weedmaster ARGO can also be sprayed one hour prior to sowing and is backed by a 20 minute commercial rainfast offer*, allowing growers to continue spraying right up to a rainfall event. WEEDMASTER ARGO COMPATIBILITY A standout feature of weedmaster ARGO and Dual Salt Technology is the superior compatibility compared to single salt glyphosate formulations. The image (left) shows mixing of two single salt glyphosate formulations with Amicide Advance 700 compared to weedmaster ARGO in 50L/ha 3WHO (1000ppm) water two hours after mixing. Note the significant salting out that can occur when mixing single salt glyphosates in these type of conditions.

1.58L/ha 540g/L single salt glyphosate + Amicide Advance 700 Significant salting out
1.5L/ha 570g/L single salt glyphosate + Amicide Advance 700 Significant salting out

EXCELLENT HANDLING CHARACTERISTICS Easy pumping in cold temperatures As temperatures drop in the cooler autumn months, liquids herbicides can become thicker and harder to pump. Some glyphosate formulations become significantly more viscous in cold conditions. weedmaster ARGO has been extensively tested to ensure the product still pumps easily under colder conditions. Even at 5°C, weedmaster ARGO can be pumped easily to ensure fast handling and mixing. Low foaming for faster tank filling After agitation, weedmaster ARGO has only half the level of foaming compared to a standard 450 CT glyphosate formulation. Less foaming allows faster pumping. APPLYING WEEDMASTER ARGO weedmaster ARGO should be applied at a COARSE to VERY COARSE spray quality. The recommended water volumes are:
WEEDMASTER ARGO THE HIGH PERFORMANCE KNOCKDOWN SPECIALIST • weedmaster ARGO is a superior, fully loaded 540g/L Dual Salt Technology glyphosate • Rapid plant uptake and translocation • Exceptional tank mix compatibility with a wide range of products including TriflurX®, Avadex® Xtra and TERRAIN®
• 20L/ha for aerial application
• Easy to handle, with reduced foaming and improved viscosity
For multiple product tank mixes, Nufarm recommends a minimum water volume of 50L/ha. Correct mixing order is important, as is good in-tank agitation when application is occurring.
• Developed and manufactured in Australia by Nufarm
When applying with pre-emergent herbicides such as TriflurX, use constant agitation to avoid separation and oil layer forming. Apply a minimum water volume of 70L/ha water.
• Backed by a 20 minute commercial rainfast offer*
• 80L/ha for broadacre ground application
