The efficacy of herbicide glyphosate can significantly depend on the quality of water used for the preparation of spray solutions. Data on the effectiveness of the adjuvants use for increase the phytotoxic effect of glyphosate are quite contradictory, which may be due to differences in the sensitivity to water quality of different glyphosate formulations. In this regard, the dependence on the quality of water in the spray solution of different glyphosate formulations action and the possibility of increasing the efficacy of these formulations by adding adjuvant Companion Gold were studied in pot and field experiments. It was shown that the phytotoxic effect of herbicide Clir, which contains the isopropylamine salt of glyphosate, was more influenced by the hardness of water, than the effect of herbicide Uragan Forte, whose active ingredient is the potassium salt of glyphosate. Addition of the adjuvant Companion Gold to the herbicide Clir accelerated the development of phytotoxic action and increased the effectiveness of weed control, which indicates the advisability of using an adjuvant with formulations based on isopropylamine salt of glyphosate.
