Summary: Cinmethylin, a pre-emergent herbicide, effectively inhibits the fatty acid thioesterase of Alopecurus myosuroides. Delayed sowing of winter wheat and winter barley improves the efficacy of cinmethylin against this problematic weed in Europe. The herbicide achieved over 90% efficacy in winter wheat and winter barley sown in mid-October, with a higher efficacy compared to flufenacet.

Summary: Integrated weed management, including stubble treatments and pre-emergence herbicide application, is necessary for controlling Alopecurus myosuroides. Field experiments in Germany showed that a combination of cultural methods and the herbicide cinmethylin effectively controlled the weed population and prevented herbicide resistance development.

Summary: The paper investigates the potential and challenges of using harvest weed seed control (HWSC) as an alternative non-chemical weed control strategy in Europe. Initial research in Europe has identified several weed species suitable for HWSC, but there are challenges such as inconsistent crop and weed maturity. Further research and development are needed to evaluate and promote the practical adoption of HWSC strategies in European cropping systems.

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: Weather conditions do not have a consistent impact on weed seed shatter, while individual weed plant biomass is positively correlated with seed-shattering rates. Harvest weed seed control has the potential to reduce inputs from plants that have escaped early management, but individuals that shatter seeds early pose a risk of escaping control measures.

Summary: The allelopathic effect of Moringa leaves applied as organic manure in tiger nut production was investigated. The results showed that the application of Moringa leaves significantly reduced weed cover, density, and dry matter production. It was recommended to apply 10 t/ha of Moringa leaves and plant large or medium-sized tubers for optimum weed suppression in tiger nut production.

Summary: This study revealed that adequate rainfall within the first 15 days after PRE herbicide application is crucial for effective weed control. Herbicide combinations require less rainfall to maximize the probability of effective control and are more successful in controlling weeds compared to herbicides applied individually.

Summary: Herbicide resistance is a significant issue in weed management. Glyphosate is the dominant herbicide used and controls a wide range of weeds, including Lolium rigidum. Some populations of L. rigidum in Australia have developed resistance to glyphosate and can now grow throughout the summer. The resistance of three L. rigidum populations, including a glyphosate-resistant summer-emerging population, a glyphosate-susceptible winter-emerging population, and a winter-emerging population with unknown resistance status, was analyzed. The analysis showed that the summer-emerging glyphosate-resistant population was significantly more resistant to glyphosate than the winter-emerging glyphosate-susceptible population. However, no target-site mutations were found in the resistant population, suggesting non-target-site resistance.

Summary: The world's population growth has led to increased pressure on agricultural production, exacerbated by climate change, water scarcity, and reduced arable land. Weeds can negatively impact food production, but they also serve as indicators of biodiversity. Effective and sustainable weed management is necessary to balance resource competition without harming the agrarian ecosystem. Overreliance on mechanization and herbicides should be avoided, while addressing herbicide resistance. Advances in weed control technologies offer the potential for increased food production, reduced inputs, and minimized environmental damage, contributing to more sustainable agricultural systems.

Summary: This article introduces a generic Bayesian network model called PRReSTo, which estimates likely infestation rates of host items in consignments. PRReSTo takes into account the vulnerability of host items to pest infestation, the abundance of pests to which host items are exposed, and the effects of risk-reducing measures. PRReSTo can be used to evaluate the effectiveness and acceptability of risk reduction measures in different pest-host systems.

Summary: Colletotrichum and Alternaria species have become emerging fungal pathogens causing severe economic losses in citrus orchards in the Mediterranean area. The use of copper-based antimicrobials for disease management is increasingly problematic, and research for alternative formulations is encouraged. This study tested copper-alternative products on citrus orchards and found that they significantly reduced disease incidence and severity, often showing comparable or better efficacy than copper. The good efficacy of these products suggests their potential for sustainable and large-scale use in integrated and organic citriculture.

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: The giant borer, Telchin licus, is a significant pest of sugarcane in Central and South America, and traditional control methods are ineffective due to the larvae's hiding behavior. Recent research has shown that transgenic sugarcane expressing Bacillus thuringiensis proteins, originally developed to control another sugarcane pest, can also effectively control the giant borer.

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.
