“…A. myosuroides is well adapted to early sowing dates in September Clarke 1994, Lutman et al 2013). Late sowing of winter wheat in October and November significantly reduced A. myosuroides emergence (Gerhards et al 2016, Menegat andNilsson 2019) and still provided sufficient time for vegetative wheat development.…”

Cinmethylin is a potential new pre-emergence herbicide in Europe inhibiting the fatty acid thioesterases in the plastid against Alopecurus myosuroides and other grass-weeds in winter cereals and oil-seed rape. Five field experiments were conducted in Southwestern Germany from 2018 until 2020 to assess the control efficacy of cinmethylin and other common pre-emergence herbicides alone and combined with post-emergence herbicides against A. myosuroides and yield response of winter wheat and winter triticale. In four experiments, the effect of early and late sowing of winter cereals was included as the second factor in the experiment to investigate if late sowing can reduce A. myosuroides density weed control efficacy. All fields were heavily infested with A. myosuroides with average<br /> densities of 110–730 plants/m<sup>2</sup>. Late sowing reduced densities in three out of four experiments. Herbicides controlled 42–100% of the A. myosuroides plants. However, none of the treatments was consistently better than the other treatments over all experiments. In three out of 5 experiments, grain yields were significantly increased by the herbicide treatments. The results demonstrate that cinmethylin increases the options for controlling A. myosuroides in winter cereals. However, it needs to be combined with other control tactics.

“…The significant reduction in days to 50% flowering with N and P fertilizer micro dosing and either single weeding at 20 DAS and double weeding at 20 and 45 DAS is evidence that N and P are limiting nutrient and that finger millet requires early weed control. Furthermore, the reduction in days to 50 % flowering by three and two days when finger millet was micro dosed with a combination of N and P micro dose (16.6 kg N ha -1 and 10.6 kg P ha -1 ) and weeding at 20 DAS; and double weeding at 20 and 45 DAS respectively is evidence that early weed control in finger millet was necessary in order to minimize competition for nutrients by weeds (Kamara et al, 2014;Menegat & Nilsson, 2019). This enables the crop to maximally utilize the N and P fertilizer micro dose applied.…”

“…Finger millet N uptake is dependent on many factors including weed species and density, the rate and formulation of applied N fertilizer. Understanding interactions among finger millet, N applied and weeds is important in developing weed management strategies (Menegat & Nilsson, 2019) and also soil fertility management (Opole et al, 2013;Asargew & Shibabawu, 2014). Therefore, weeds are of economic importance to farmers and one of the major constraints to worldwide crop production.…”

Finger millet yields in farmers’ fields are low primarily due to low soil fertility and poor weed management. Fertilizer application could be one of the key strategies used to address the problem. However, due to high cost of fertilizer, its utilization has been limited to very few farmers in the country. Consequently, a study was conducted in Kuju sub-county, Amuria district in Eastern Uganda during 2016 long and short rains to determine the effect of micro dosing and weeding time on finger millet performance and weed growth. The experiment was laid out in a randomized complete block design in a split plot treatment structure. Weeding times constituted the main plot [weeding at 20 DAS (days after sowing), 30 DAS, 45 DAS, and 20 & 45 DAS (double weeding)], while fertilizer rates (N 16.6 kg ha-1 + P2O5 10.6 kg ha-1; P2O5 10.6 kg ha-1; N 16.6 kg ha-1; N0 + P0, and N 83 kg ha-1 + P2O5 52 kg ha-1) constituted the sub plots. Results of this study revealed that the interaction between weeding at 45 DAS and fertilizer micro-dosing significantly (P < 0.05) reduced weed biomass (7.7 × 10-4 kg ha-1) without significant increase in finger-millet grain yield. Interaction of fertilizer micro-dosing (N 16.6 kg ha-1 + P2O5 10.6 kg ha-1) with weeding once at 20 DAS recorded the highest (2292 kg ha-1) finger millet grain yield with significant (P < 0.05) reduction in days to finger millet flowering. Therefore, it is recommended that fertilizer micro-dosing at N 16.6 kg ha-1 + P2O5 10.6 kg ha-1 and weeding once at 20 DAS can be used to control weeds and enhance finger-millet productivity.

“…The low base temperature (0–1 °C) for germination [ 1 , 12 ], combined with a short primary dormancy, gives this weed species a broad emergence spectrum, which further increases its competitiveness [ 13 ]. As a weed species whose life cycle reveals a wide range of adaptation to conventional cropping systems [ 14 ], A. myosuroides peak emergence occurs in early autumn, coinciding with the sowing time and early development stage of winter cereals. Weed emergence is most commonly observed between October and December (80% of the population), and usually hibernates in two developed leaves or in the tillering phase.…”

Alopecurus myosuroides Huds. is an important pinoxaden-resistant grass weed in many countries of Europe. Recently, the low efficacy of pinoxaden was reported in winter cereals in Croatia, but a preliminary dose–response trial showed no herbicide resistance for the investigated weed population. Therefore, a two-year experiment was conducted under greenhouse conditions to determine the efficacy of various pinoxaden doses (20, 40 and 80 g a.i. ha−1) on weed visual injuries and biomass reduction after herbicide application at different growth stages. As expected, the maximum weed biomass reduction (97.3%) was achieved by applying the highest dose (80 g a.i. ha−1) at the earliest growth stage (ZCK 12–14). A pinoxaden dose of 20 g a.i. ha−1 resulted in satisfactory weed biomass reduction (88.9%) only when applied at ZCK 12–14. The recommended dose (40 g a.i. ha−1) also provided sufficient weed control up to the growth stage ZCK 21–25. Slightly delayed (ZCK 31–32) application of the recommended dose brought about a low weed biomass reduction (60.1%). Double than the recommended dose also failed to provide satisfactory weed control at the advanced weed growth stages (ZCK 31–32 and ZCK 37–39). Thus, reported low efficacy of pinoxaden is most likely because of delayed herbicide application when A. myosuroides is overgrown.
