%X Interaction of pollutions is one of the research focuses in current environmental sciences. The combined toxicity of copper and glyphosate to the inhibition rates of wheat germination, sprout length and root elongation was studied. Results indicated that Cu2+ had no obvious effect on the wheat germination but could inhibit the root elongation and sprout length significantly. Glyphosate had obvious inhibition effect on the wheat germination, sprout length and root elongation. When Cu2+ and glyphosate were combined, the presence of Cu2+ decreased the inhibition of glyphosate to wheat germination and sprout length. But for the root elongation, the Cu2+ increased the toxicity of glyphosate when glyphosate was at low concentrations and decreased the toxicity of glyphosate to root elongation when glyphosate was at high concentrations. The possible reason of Cu2+ decreased the eco-toxicity of glyphosate is the complexation reaction of Cu2+ and glyphosate.
