Other claims from this paper (9)
- Intervention effect Tween 20, X-77 and Triton X-100 enhanced the effectiveness of low glyphosate rates in field studies.
- Intervention effect Triton X-A Special and Tween 20 enhanced glyphosate phytotoxicity in wild oats and barley in greenhouse studies.
- Intervention effect At least 0.5% vol/vol Tween 20 was required for enhancement of glyphosate phytotoxicity in barley.
- Intervention effect At least 0.25% vol/vol Triton X-A Special was required for enhancement of glyphosate phytotoxicity in barley.
- Intervention effect Renex 36, Cittowet Plus and Dupont WK reduced glyphosate phytotoxicity in field and greenhouse studies.
- Intervention effect Atplus 411F, Surfel and Triton X-114 reduced glyphosate effectiveness in several field treatments.
- Intervention effect Increasing spray volume reduced the effectiveness of low glyphosate rates, more so in tap water than in distilled water.
- Intervention effect Ammonium sulphate in combination with Agral 90 enhanced glyphosate phytotoxicity in barley.
- Intervention effect Other surfactants had no significant effect on glyphosate phytotoxicity.
