Weeds are a perennial problem in coconut plantations and cause significant losses in the nut yield.The occurrence of a wide range of weeds also causes difficulties in their eradication.The influence of five different weed management practises on the distribution and composition of the soil weed seed bank in coconut plantations in the low-country dry zone of Sri Lanka was evaluated. The treatments imposed included the application of glyphosate (N-[phosphonomethyl]-glycine), cover cropping with Pueraria phaseoloides, tractor harrowing, tractor slashing, and tractor plowing.All the treatments were applied twice per year, except for the cover cropping treatment. In terms of a reduction in the weed biomass, the application of glyphosate and cover cropping (Pueraria) were more efficient in reducing the ground weed population.These methods were very effective in reducing the weed seed density in the top soil layers. Plowing and harrowing significantly reduced the seed bank in the top soil layers and shifted significant numbers of weed seeds to deeper soil profiles. However, the total germinated weed seed count increased by 123.5, 691.4, 1133.1, and 1216.5% in the 10-15, 15-20, 20-25, and 25-30 cm soil depths, respectively, compared with the initial germinated weed seed count in the plowing treatment. Considering all the soil layers, the decline in the germinating weed seed count was very high in the treatment plots with cover cropping and the application of glyphosate; thus, these are considered to be the best practises to reduce the germinating weed seed count in the soil of coconut plantations.

The impact of different weed control treatments on soil seed bank dynamics was studied at Torrington, WY, for a corn/sugarbeet and barley/sugarbeet crop rotation. Common lambsquarters, hairy nightshade, and redroot pigweed accounted for 90% of the total weed seed in the soil seed bank. Samples collected after corn or barley harvest showed no significant differences in total seed numbers due to herbicide treatments; however, differences were evident in samples collected following sugarbeet harvest. Glyphosate applied postemergence at the 2 and 6 true‐leaf sugarbeet stage or the conventional treatment of ethofumesate preplant plus two postemergence applications of triflusulfuron plus phenmedipham / desmedipham / ethofumesate plus clopyralid in sugarbeet reduced the total number of weed seed in soil following all corn treatments. The reduction in total seed bank numbers was due to the decrease in redroot pigweed and hairy nightshade seed density. An increase in total seed bank numbers was observed when the micro‐rate treatment (three postemergence applications of triflusulfuron plus phenmedipham / desmedipham / ethofumesate plus clopyralid) in sugarbeet followed any barley treatment. No sugarbeet treatment reduced total seed numbers following untreated plots in either barley or corn.

“…Propagule pressure and soil seed banks are a major driver for grass infestations in disturbed areas (Smith et al 2000;Bellairs et al 2006;Fensham et al 2013). Once contaminated, the soil seed bank can allow regular recruitment and facilitate long-term persistence of major infestations of grass weeds despite intensive management (Burnside et al 1986), compromising the success of restoration efforts with native species (Grant & Koch 1997;Bayliss et al 2006 Managing the soil seed bank to avoid establishment of weeds is a critical element for successful mining restoration in Australia (Mulligan 1996). However, current management plans for Gamba Grass focus on control of mature plants through the application of the 'knock-down' herbicide glyphosate, burning and slashing (NT Weed Management Branch 2018).…”

Summary Weed invasion is a major threat to Australian tropical savannas, and controlling weeds is essential for successful re‐establishment of native species on disturbed sites. Gamba Grass (Andropogon gayanus) is an African grass which has invaded large areas of tropical savanna across northern Australia. Current management strategies in northern Australia focus on fire and glyphosate to effectively control mature plants; however, re‐establishment of infestations from the soil seed bank remains a major challenge to eradication efforts. This study focused on the effects of soil seed bank treatments on Gamba Grass recruitment on a mine site in northern Australia. Adult Gamba Grass plants within test plots were killed with glyphosate to exclude resource competition. Chemical, physical and biological treatments were then applied, and the treatment effects on subsequent Gamba Grass seedling emergence and survival quantified. Seedling emergence was significantly reduced by three of the four residual herbicide treatments tested. The most effective herbicide treatments, dalapon and sulfometuron, reduced emergence by 90% compared to the standard glyphosate treatment alone. This equated to a reduction in Gamba Grass seedling emergence from 1 seedling/m2 to 1 seedling 10 m−2, a major improvement for Gamba Grass management. These residual herbicide treatments significantly reduced the population density of Gamba Grass for at least 5 months after emergence. The physical and biological treatments did not have a significant effect on seedling emergence. This significant reduction in Gamba Grass seedling emergence and survival can substantially improve Gamba Grass management. Reducing re‐colonisation from the soil seed bank using residual herbicides provides a valuable management tool for land managers, integrating readily with established strategies for controlling the mature plants.
