摘要

2023年9月，印度旁遮普Lovely专业大学的Aspidistra elatia（铸铁植物）在43个盆栽中发现了叶枯病，其特征是坏死的棕褐色斑点，边缘呈深褐色，并有黄色晕，随着疾病的发展，叶子会枯萎。对lpu1 ~ lpu6 6株真菌进行了培养和鉴定，并通过rDNA、翻译延伸因子1- α和β -微管蛋白基因的内部转录间隔区（ITS）测序证实了它们的鉴定。科赫的假设是通过用孢子悬浮液接种健康的黄连植物来实现的，从而导致症状的发展。从感染叶片中分离得到的真菌分子和形态分析表明，沙兰帕斯卡多洛多毛孢是该植物病害的致病因子。科赫的假设成功地从接种过的植物中恢复了同样的病原体。这是第一次报道在印度引起叶白病的p.a arengae。

Occurrence of Pestalotiopsis arengae as a leaf blight pathogen on Aspidistra elatior in Punjab, India

In September 2023, Aspidistra elatior (cast iron plant) at Lovely Professional University, Punjab, India, exhibited a leaf blight disease in 43 potted The disease was characterized by necrotic tan spots with dark brown margins and yellow halos followed by blighting of leaves in advancement of disease. Six fungal isolates (LPUP1 to LPUP6) were cultured and characterized, and their identification was confirmed through sequencing of the internal transcribed spacer (ITS) region of rDNA, translation elongation factor 1-alpha and beta-tubulin gene. Koch's postulates were fulfilled by inoculating healthy A. elatior plants with spore suspensions, resulting in symptom development. Molecular and morphological analysis of fungal isolates obtained from infected leaves identified Pasestalotiopsis arengae as the causal agent of theplant disease. Koch's postulate successfully recovered the same pathogen from inoculated plants. This is the first report of P. arengae causing leaf blight in A. elatior in India.

期刊介绍： The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
