Residual effect of glyphosate as a ripener on sugarcane.

R. A. Donaldson; N. G. Inman Bamber 1982

Other claims from this paper (5)

Intervention effect In one large trial with three successive sprayed crops, no residual effect of glyphosate on yield was found.
Intervention effect The residual activity of glyphosate was low in several trials under optimum moisture conditions.
Intervention effect Glyphosate increased sugarcane yields considerably through its ripening effect.
Intervention effect Glyphosate applied to the preceding crop reduced sugarcane yields by 11 to 17% in rainfed trials affected by drought.
Recommendation Glyphosate should be used only where cane is not stressed or likely to be stressed between spraying and harvesting.
