 摘要： This paper provide a comprehensive overview of research findings regarding the pathogen responsible for tobacco brown spot, its occurrence regularity, and integrated control strategies. Additionally, this study provide a brief analysis of the challenges encountered in the study of tobacco brown spot, which include the study of pathogenesis and virulence, the breeding of disease-resistant varieties, the screening of low-toxicity and high-efficiency agents, the development of biological control methods with more stable efficacy, and the necessity for accurate prediction and forecasting techniques.

 摘要： [Objectives] To screen effective agents for the management of root rot in tobacco floating seedlings. [Methods] A total of eight treatments were implemented in a large-scale field trial, which included three replications. Each treatment was administered at the recommended dosages. [Results] The application of Metalaxyl-M·Fludioxonil+amino acids demonstrated a control efficacy of 93.65% against root rot in tobacco floating seedlings. In comparison, the application of Metalaxyl-M·Fludioxonil alone exhibited a control efficacy of 88.42%. The most effective treatment for promoting root growth in tobacco seedlings was Metalaxyl-M·Fludioxonil+amino acids, which resulted in a 54.65% increase in root growth compared to the blank control. This was followed by the application of Metalaxyl-M·Fludioxonil alone, which yielded a 39.53% increase in root growth relative to the blank control. [Conclusions] The application of Metalaxyl-M·Fludioxonil+amino acids is recommended for use in the seedling pools of tobacco seedling cultivation. Specifically, it is advised to incorporate 1 mL of Metalaxyl-M·Fludioxonil and 2 mL of amino acids into each seedling tray prior to their introduction into the seedling pool. This treatment has demonstrated significant efficacy in preventing and controlling root rot in tobacco floating seedlings, while also promoting the health of the root system and ensuring the quality of transplanted tobacco seedlings.

 摘要： Given that the citrus psyllid is the primary vector of citrus Huanglongbing (HLB), there is an urgent need to control this pest to mitigate the spread of the disease. This paper reviews the current research on two predominant control strategies: chemical control and biological control agents, in managing the citrus psyllid. It emphasizes the mechanisms of action, efficacy, and application advancements of these control methods. Finally, the paper analyzes the principal challenges associated with the sustainable management of citrus psyllids and offers perspectives for future research.

 摘要： [Objectives] To address the weeding challenges within the corn and soybean strip intercropping field and identify appropriate herbicide types and application methods suitable for the corn and soybean strip intercropping fields in Siyang County. [Methods] The trial comprised six herbicide treatments and one blank control, with investigations conducted to assess efficacy, safety, and yield. [Results] Each herbicide treatment effectively controlled weeds, demonstrated high safety, and enhanced the yields of both soybeans and corn. The combined application of soil sealing with stem and leaf spray exhibited superior overall weed control compared to soil sealing alone. At 28 d following stem and leaf spray, the plant control effect and fresh weight control effect against weeds in the combined treatment of soil sealing with stem and leaf spray all exceeded 89%. [Conclusions] This study offers technical support for advancing the practice of strip intercropping between corn and soybeans.

 摘要： [Objectives] To systematically investigate the microbial community composition of rhizosphere soil and endophytes associated with Pogostemon cablin, and to explore the relationships between endophytes and rhizosphere microorganisms as well as their potential applications. [Methods] Microbial isolates were obtained from rhizosphere soil, root tissues, and stem tissues using the serial dilution and spread plate method. These isolates were identified through morphological characterization, physiological and biochemical assays, and molecular biological techniques. [Results] A total of 18 microbial strains were isolated, including 7 bacterial and 11 fungal strains. Among the bacterial isolates, Pseudomonas spp. and Bacillus spp. were predominant, while the fungal isolates were mainly represented by Aspergillus spp. Certain bacterial strains, notably Pseudomonas spp., exhibited potential abilities for indole-3-acetic acid (IAA) production, nitrogen fixation, and antagonistic activity against pathogenic microorganisms, suggesting their potential utility as biocontrol agents and promoters of plant growth. [Conclusions] This study establishes a foundational understanding of the microbial community characteristics in the rhizosphere and tissues of P. cablin, as well as their roles in plant growth and development.

 摘要： The prevalence of Solenopsis invicta is associated with habitat diversity, with a preference for various habitats ranked in the following order: ponds, wastelands, green belts, roads, parks, farmlands, and villages. Consequently, management strategies should be tailored to each habitat. There are two occurrence peaks of S. invicta throughout the year, specifically from March to April and from September to October. It is essential to emphasize prevention and control measures during the active periods of S. invicta. To enhance the effectiveness of these measures, supplementary control should be implemented within 10-15 d following the initial prevention and control efforts. Furthermore, the efficacy of prevention and control is notably higher on the second to third day immediately following rainfall. This study aimed to evaluate the efficacy of various agents in controlling S. invicta. A comparative analysis was conducted on the efficacy of three different brands of agents against S. invicta. The findings indicated that a concentration of 0.08%-0.10% indoxacarb exhibited a comparable extermination effect on S. invicta worker ants. However, agents with larger particle sizes demonstrated a reduced efficacy in exterminating S. invicta nests.

 摘要： [Objectives] To analyze the composition of lycophytes and ferns in Yunzhongshan Nature Reserve, Fujian Province. [Methods] This study examined the composition of lycophytes and ferns in Yunzhongshan Nature Reserve through field investigations and specimen identification, supplemented by a review of relevant literature. [Results] A total of 84 species of lycophytes and ferns were identified, encompassing 55 genera and 29 families. This included 14 species of lycophytes distributed across 8 genera and 3 families, as well as 70 species of ferns belonging to 47 genera and 26 families. Polypodiaceae and Selaginella were the dominant family and genus, respectively, while oligospecific families and monotypic genera were significant components of lycophytes and ferns in the region. The distribution types of these families were primarily cosmopolitan and tropical. The Germline differentiation degree (SD) was 3.34, and the proportion of rare or endangered species among lycophytes and ferns was 8.33%. [Conclusions] Yunzhongshan Nature Reserve possesses a diverse array of lycophyte and fern species. This study offers valuable scientific insights that can inform efforts related to the conservation of biodiversity, resource utilization and development, species introduction, and system evolution of lycophytes and ferns within the reserve.
