Abstract:
A process for treating a plant with glyphosate comprising the steps of:(a) applying to foliage of the plant an anthraquinone compound; and(b) applying a biologically effective amount of said glyphosate to the same foliage; wherein:said anthraquinone compound is applied in a substantially non-phytotoxic amount of at least about 0.25 g/ha but not sufficient to antagonize effectiveness of said glyphosate;said glyphosate is N-phosphonomethylglycine, a salt of N-phosphonomethylglycine, an ester of N-phosphonomethylglycine, a compound which is converted to N-phosphonomethylglycine in plant tissues, or a compound which otherwise provides N-phosphonomethylglycine in ionic form; andthe biological effect on a plant treated with said anthraquinone compound and said glyphosate is greater than the biological effect on a plant treated with said glyphosate but without said anthraquinone compound.
