Other claims from this paper (19)
- Intervention effect Glyphosate formulations did not influence corn injury, weed control, or grain yield.
- Intervention effect No preemergence herbicide system effectively controlled annual grasses.
- Intervention effect Preemergence herbicide plus glyphosate controlled goosegrass by more than 86%.
- Intervention effect Preemergence herbicide plus glyphosate controlled large crabgrass by more than 86%.
- Intervention effect Preemergence herbicide plus glyphosate controlled Texas panicum by more than 86%.
- Intervention effect Postemergence glyphosate controlled common ragweed at least 88%.
- Intervention effect Postemergence glyphosate controlled common lambsquarters at least 89%.
- Intervention effect Specified preemergence and glyphosate programs controlled Ipomoea species at least 88%.
- Intervention effect Glyphosate applied once or twice gave the highest corn yields.
- Observation Glyphosate weed-management systems had the highest net returns.
- Intervention effect Glyphosate applied at V6 or later reduced corn pollen viability across hybrids.
- Association Later glyphosate treatments were associated with pollen morphological alterations, large vacuoles, and lower starch accumulation.
- Intervention effect Glyphosate did not influence corn pollination or seed set.
- Observation CP4-EPSPS expression at anthesis was greatest in pollen and declined across listed corn tissues.
- Intervention effect Glyphosate did not change sicklepod pod length, seed germination or viability, or aboveground biomass.
- Intervention effect Glyphosate application at 4 L, 8 L, 12 L, and sequentially reduced sicklepod flowers by 29, 5, 65, and 54%, respectively.
- Intervention effect Glyphosate at 112 and 280 g/ha reduced sicklepod flowers by 19 and 58%, respectively.
- Intervention effect At 280 g/ha, glyphosate reduced sicklepod pod number, seed number, and total seed weight by 78, 80, and 81%.
- Observation Cotton showed visual injury and shikimic acid accumulation above 70 g/ha glyphosate; the authors proposed these at 7 DAT as indicators of yield reduction.
