Other claims from this paper (12)
- Intervention effect A single application of 0.28 kg/ha glyphosate reduced chlorophyll content in susceptible soybean by 49% at 2 weeks after treatment.
- Intervention effect A single application of 0.28 kg/ha glyphosate reduced shoot and root dry weight in susceptible soybean by 50 and 57%, respectively, at 2 weeks after treatment.
- Intervention effect A single application of 2.24 kg/ha glyphosate reduced shoot and root dry weight of glyphosate-resistant soybean by 25 to 30%.
- Intervention effect Glyphosate applied at 2.24 kg/ha followed by sequential application of 2.24 kg/ha reduced root growth of soybean.
- Intervention effect Glyphosate at 2.24 kg/ha reduced nodule number and nodule mass of glyphosate-resistant soybean by 30 and 39%, respectively, compared with untreated plants.
- Intervention effect Glyphosate at 1.12 kg/ha applied 3 weeks after planting did not affect nodule number or mass of glyphosate-resistant soybean.
- Intervention effect Glyphosate reduced leghemoglobin content of nodules by 6 to 18% at both rates, with inconsistent effects across rates.
- Intervention effect At 18/13 °C day/night, glyphosate at 1.12 or 2.24 kg/ha did not affect chlorophyll and growth of glyphosate-resistant soybean.
- Intervention effect At 25/20 and 32/27 °C day/night, glyphosate at 2.24 kg/ha reduced chlorophyll content and growth of glyphosate-resistant soybean.
- Intervention effect Glyphosate at 1.12 kg/ha had little or no effect on chlorophyll content and shoot and root dry weight of glyphosate-resistant soybean in five of five trials.
- Intervention effect Glyphosate at 2.24 kg/ha reduced chlorophyll content and shoot and root dry weight of glyphosate-resistant soybean in three of five trials.
- Intervention effect Subtle reductions of nodulation occurred in glyphosate-resistant soybean at label rates of glyphosate, probably of minimal consequence.
