Nufarm weedmaster® DUO® is fully loaded with an aquatically approved surfactant for use with high water rates in horticulture and industrial situations.

Unlike other 360 gm glyphosate formulations, Nufarm weedmaster DUO contains two salts to improve plant uptake. The result is, better weed control that also gives you extra flexibility thanks to its enhanced tank mix compatibility.

Nufarm weedmaster DUO has the added advantage of full aquatic registration, so it can be used in sensitive areas.

NUFARM weedmaster DUO – THE PRODUCT Nufarm weedmaster DUO contains 360 g/L of glyphosate, present as the isopropylamine and mono-ammonium salts. The important difference between Nufarm weedmaster DUO and other 360 g/L glyphosates is that it uses those two bases to form soluble glyphosate salts – the unique Dual Salt Technology process developed by Nufarm. The inclusion of mono-ammonium salt along with a unique surfactant package accelerates the progress of glyphosate through the cuticle into the plant sap transport system.
