Summary: The Ontario government carried out the first large-scale over-water application of glyphosate to control the invasive European Phragmites australis in Canadian history. Concentrations of glyphosate in water reached a maximum of 0.320 mg/L within 24 hours of application, while concentrations returned to pre-treatment levels within one year. The herbicide did not reach levels of toxicological concern for aquatic biota according to the Canadian Council of Ministers of the Environment.

Summary: The study demonstrates that osmotic shock is effective in controlling the invasive brackish water clam Rangia cuneata, with high salinities being able to rapidly kill the clams and even modest increases in salinity potentially preventing their recruitment.

Summary: Plant biomass, especially aquatic plant biomass, has gained significant attention for its potential as an alternative feedstock for bioenergy production. Pretreatment of invasive aquatic plant biomass is necessary to improve the conversion efficiency and yield. This review analyzed existing literature on the pretreatment of aquatic lignocellulosic biomass, highlighting the need for further research on different types of aquatic plants to explore their potential for producing high-value products and biofuels.

Summary: Ludwigia decurrens, a dicotyledonous plant species, has been identified as an invasive noxious weed that competes with rice and significantly reduces rice production. A population of L. decurrens in Indonesia showed resistance to the herbicide penoxsulam, which poses a serious environmental and economic issue. Further research is needed to develop herbicide resistance management strategies for controlling herbicide-resistant populations of L. decurrens.

Summary: Aquatic invasive plants can have significant impacts on ecology and economy, making effective management essential. However, there is limited research on recreational user engagement in biological control, and existing studies have given little emphasis on important predictors from outdoor studies. This study explores the factors influencing recreational users' willingness to participate in controlling aquatic invasive plants, and finds that recreational factors, knowledge of invasive plants, and participation in water-based activities are significant incentives to engage.

Summary: Invasive plants have a significant impact on the forests in eastern North America, and the effectiveness of management strategies varies depending on the context. Long-term success requires comprehensive approaches to address the impacts of past land use and disturbance history.

Summary: Solanum rostratum Dunal, an invasive weed species in Israel, has seen an increase in distribution range and new populations discovered recently. The study found that Carfentrazone-ethyl is highly effective in controlling the weed at different growth stages, while some herbicides like Metribuzin and oxadiazon show reduced efficacy at later growth stages. Tank mixes with surfactants can improve control of later growth stage plants. These herbicides can aid in preventing further spread and buildup of S. rostratum field populations.

Summary: Nutrient pollution is causing the spread of invasive aquatic plants in various water bodies. This study examined the response of aquatic macrophytes in two estuaries with different nutrient inputs. The study found that effluent discharge from wastewater treatment plants promoted the establishment of invasive alien aquatic plants in one estuary, while nutrient pulses associated with high rainfall changed the composition of macrophytes in the other estuary.

Summary: In this study, the individual and combined effects of glyphosate and AMPA on the physiology of mosquito larvae were evaluated. The presence of the aquatic macrophyte, Salvinia molesta, was found to mitigate the toxicological impacts of the compounds by removing them from the water.

Summary: Invasive plant management is crucial for the restoration of native plant communities. This study found that glyphosate-treated invasive plants can release glyphosate into the environment, but the negative impacts on the germination and growth of native plants are short-term. Early-stage growth is important for successful establishment, thus invasive plant managers should consider the species-specific effects of glyphosate and leachate in planning restoration activities.

Summary: Until recently, there has been limited research on the population dynamics and genetic variation of invasive species. This study focuses on the population dynamics of Kalanchoe delagoensis and explores the impact of its reproductive strategy on population growth rate. The results show that plantlet survival and recruitment are crucial factors for population growth, and different management scenarios have varying effects on population growth rate.

Summary: Estuaries are important ecosystems that are threatened by non-native invasive species, including submersed aquatic vegetation. Herbicides are commonly used to control this vegetation, but most evaluations have been done in lentic systems, not estuaries. A study in the Sacramento-San Joaquin Delta found that a widely used herbicide was not effective in controlling vegetation in this estuarine ecosystem. This highlights the need for tailored management tools for estuaries.
