Summary: Research has shown that using cyanobacteria, such as Arthrospira platensis, Desmonostoc muscorum, and Anabaena oryzae, through foliar spraying is an effective approach to induce immunity against Fusarium wilt in Capsicum annuum L. These cyanobacterial extracts significantly reduced the risk of infection and improved plant growth, metabolic characteristics, and phenol levels. The application of cyanobacteria also enhanced the activity of antioxidant enzymes and altered the endogenous hormone content in the infected plants.

Summary: Banana Fusarium wilt caused by Fusarium oxysporum f. sp. cubense is a disastrous fungal disease. Strain WHL7 of Streptomyces sp. isolated from marine soft coral showed high antifungal activity against Foc TR4. Fermentation broth of Streptomyces sp. WHL7 significantly increased the resistance of banana plantlets to Foc TR4, making it a potential bioresource for controlling Foc TR4.

Summary: This study aimed to identify factors influencing the efficacy of biopesticides against Fusarium wilt in asparagus and assess the efficacy of Trichoderma-based biopesticides under different conditions. The results showed that Trichoderma species inhibited the growth of Fusarium, but high temperatures and limited water availability reduced their efficacy. The findings have implications for selecting appropriate Trichoderma species for specific environmental conditions.

Summary: This study conducted a pot experiment with spring wheat to investigate the early detection of Fusarium head blight (FHB) and the efficacy of different biological control agents (BCAs). The results showed that hyperspectral imaging (HSI) could detect the pathogen nine days after inoculation, four days earlier than visual detection. Fungal BCAs demonstrated greater efficacy compared to bacterial ones. This research provides promising alternatives to reduce the use of chemical-synthetic plant protection products.

Summary: In this study, a strain of Streptomyces, named XY006, was found to have strong inhibitory activity against Fusarium oxysporum causing banana wilt disease. Two cyclic lipopeptide homologs, lipopeptin A and lipopeptin B, were identified as the corresponding antifungal metabolites. Pot experiments showed that XY006 successfully colonized banana plantlets and suppressed the incidence of banana wilt disease. Furthermore, XY006 fermentation culture application improved plant growth parameters and induced peroxidase activity, indicating a potential role in inducing resistance.

Summary: Plant diseases caused by phytopathogens are a significant threat to global agricultural systems. Pesticides are effective in controlling plant diseases, but their use is becoming less popular due to their potential harm to humans and the environment. This study explored the biocontrol potential of an endophytic Streptomyces sp. SP5 bioformulations against Fusarium wilt. The bioformulations effectively controlled Fusarium wilt and promoted plant growth and systemic resistance.

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: This study compares the effectiveness of two fallow trapping patterns and finds that internal trapping of fallow land can clean up plots twice as quickly as trapping surrounding the fallow land. Additionally, trapping efficiency is influenced by climatic conditions, with the wet season being more favorable for trapping than the dry season.

Summary: Invasive tephritid fruit flies pose a significant threat to commercial fruit and vegetable production. Early detection is crucial, and male lures are an important component of trapping networks. This review aims to summarize data on the change in attractiveness of male lures during aging in the field, highlighting studies that relate trap captures to changes in residual content and release rate.

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.
