Summary: Efforts to reduce agriculture's reliance on pesticides, such as the EU Directive on sustainable pesticide use, have not fully led to widespread implementation of Integrated Pest Management principles. A paradigm shift in weed management is needed towards holistic integrated weed management to increase sustainability in agricultural systems. An IWM framework with five pillars is proposed to support this transition and drive the development of sustainable agricultural systems in the future.

Summary: As the forecasted increase in food demand over the next century is 50%, the need to meet this demand becomes more urgent. Thus, agronomists are advocating sensible tools and approaches, particularly in eradicating factors that hinder crop production, such as weeds. The extensive use of chemical herbicides to control weeds results in increased risks such as herbicide-resistant weed populations, environmental pollution, unsafe agricultural products, and negative effects on human health.

Summary: Population models are essential for understanding long-term changes in weed dynamics with integrated weed management strategies. The importance of achieving high control efficiencies in controlling herbicide-resistant weeds and the impact of increased barley sowing densities on weed control were highlighted. Non-herbicide methods were found to be ineffective, and a combination of control tactics is necessary for weed eradication, with the effectiveness of increased sowing density diluted as weed control becomes more demanding. Future research should focus on the effects of weed resistance levels on population dynamics and efficiencies in sustainable IWM programs.

Summary: This study investigated the effects of climate and land-use on soil carbon (C) and nitrogen (N) storage in floodplain soils in tropical drylands in northeastern Brazil. The results showed that soils in wetter climate accumulated more C and N compared to drier climate. Additionally, overgrazing reduced C and N stocks and negatively affected the chemical properties of the soils. These findings have implications for the sustainable management of floodplain soils in drylands globally.

Summary: Conservation Agriculture (CA) is a sustainable agricultural intensification strategy that can improve soils and sustain crop yields, but adoption rates in sub-Saharan Africa (SSA) are generally low due to the significant transformation required in management practices, multiple inherent trade-offs, and incompatibility with local conditions. Improving CA adoption in SSA could involve focusing on promoting CA in environments where it best fits or facilitating smallholders' adaptation of CA practices to their specific conditions and constraints.

Summary: Host plant defense mechanisms (resistance and tolerance) and plant nutrition are key components for controlling Striga weeds in tropical cereal production systems. However, neither alone is effective in preventing parasitism and crop losses. Improved plant nutrition can enhance plant resistance and tolerance against Striga. Advances in parasitic plant research, combined with insights from phytopathology and plant physiology, can help identify opportunities and gaps to develop strategies combining genetics and plant nutrition for sustainable Striga control.

Summary: While agroforestry is a well-established approach for agroecological intensification, the integration of rice with trees is less common compared to other annual staple crops. This study reviews the existing literature on integrating trees in rice production worldwide and provides perspectives for future research, with a focus on Africa. The study identifies six improved rice agroforestry practices and finds that the addition of trees can lead to a 38% increase in rice yield. However, the impacts on yield depend on the specific agroforestry practice used and its interaction with fertilizer application. Further research is needed to explore the wider environmental, social, and economic sustainability aspects of integrating trees with rice cropping.

Summary: This study updated the economic thresholds for Lygus spp., a major insect pest of canola in Canada, by integrating a large data set collected over 23 years. The results revealed that the economic injury level for Lygus was around 9-23 insects per 10 sweeps, while spraying a foliar insecticide was only necessary when Lygus catches exceeded 30 insects per 10 sweeps. Additionally, analysis of Precision Yield Data showed that at low abundances (under 17 insects per 10 sweeps), Lygus may potentially stimulate canola yield and do not require control action.

Summary: A novel methodology was proposed to analyze water-sensitive papers (WSPs) for evaluating spray quality. The segmentation of overlapping droplets based on concave point detection and ellipse fitting achieved high accuracy. A linear relationship between droplet density and coverage was observed, and simulated WSPs were generated for high coverage estimation. This approach allows for more accurate spray quality indicators from WSP collectors.
