Sensitivity of Echinochloa muricata and Echinochloa crus-galli to HPPD- and ALS-inhibiting herbicides in corn


, : Sensitivity of Echinochloa muricata and Echinochloa crus-galli to HPPD- and ALS-inhibiting herbicides in corn. Communications in Agricultural and Applied Biological Sciences 76(3): 513-520

Until recently Echinochloa muricata var. microstachya Wiegand (rough barnyardgrass), an alien species native to North America, was completely overlooked in Belgium due to its close morphological resemblance to Echinochloa crus-galli (L.) P. Beauv. (barnyardgrass). E. muricata var. microstachya has gradually spread and is now locally naturalized and abundant in and along maize fields. One of the possible reasons for its expansion in maize fields, besides e.g. the lack of crop rotation, might be a lower sensitivity to postemergence herbicides acting against panicoid grasses, in particular 4-hydroxyphenyl pyruvate dioxygenase (HPPD)-inhibiting herbicides and acetolactate synthase (ALS) inhibiting herbicides. Dose-response pot experiments were conducted in the greenhouse to evaluate the effectiveness of four HPPD-inhibitor herbicides [topramezone (ARIETTA), mesotrione (CALLISTO), tembotrione (LAUDIS), sulcotrione (MIKADO) and the ALS-inhibitor herbicide nicosulfuron (KELVIN) for controlling local populations of E. crus-galli and E. muricata. Pots were planted with 25 seeds, thinned afterwards to 5 plants (one week after sowing) and irrigated by overhead sprinklers. Herbicides were applied at the 3-4 leaf stage (BBCH stage 13-14). Fresh biomass was harvested 28 d after treatment. In another dose-response pot experiment, the influence of leaf stage at time of herbicide application on efficacy of topramezone for (rough) barnyardgrass control was evaluated. Sensitivity to HPPD-inhibitor herbicides topramezone and sulcotrione was significantly lower for E. muricata populations than for E. crus-galli populations. However, nicosulfuron sensitivity of both species was similar. Compared to E. crus-galli, sensitivity of E. muricata to topramezone was more dependent on leaf stage. Due to the intragenus variability in sensitivity to HPPD-inhibitor herbicides, higher awareness is required for presence of E. muricata plants in maize fields in order to avoid insufficient "barnyardgrass" control.
