Glyphosate Resistance of Chloris virgata Weed in Australia and Glyphosate Mobility Are Connected Problems

Abstract

The purpose of this review paper is to address two major aspects of glyphosate application on farmers' fields. The first aspect is the development of glyphosate resistance in weeds like Chloris virgata, and the second aspect is glyphosate mobility, which is directly controlled by soil sorption processes and indirectly by molecule degradation processes. This is a global problem, as excessive glyphosate residues in groundwater, drinking water, and urine of subsistence farmers from intensive agricultural localities have been reported, which can pose a risk to human health. Approaches like biochar as a possible strategy to control glyphosate leaching and crop competition as a cultural method to control glyphosate-resistant weed like Chloris virgata can be the potential solutions of the glyphosate resistance and glyphosate mobility.
