摘要

辣椒（Capsicum annuum）是一种全球种植的多年生草本植物，因其烹饪重要性和营养丰富而备受重视。2024年2月，在对茄类作物疾病的常规监测期间，在印度阿萨姆邦杜布里地区的一个种植区内，在辣椒上观察到一种具有叶枯病症状的疾病。患病症状的特征是沿叶边缘的小棕色病变，逐渐合并成较大的坏死性枯萎病，导致叶子变成棕色和枯萎。从侵染植物中分离到的病原菌经形态学和分子分析鉴定为增殖镰刀菌。科赫的假设也证实了F. proliferatum是致病因子。据我们所知，这是在印度报道的引起辣椒（Capsicum annuum）叶枯病的F. proliferatum。

First report of Fusarium proliferatum causing leaf blight of chilli (Capsicum annuum) in India

Chilli (Capsicum annuum) is a globally cultivated perennial herbaceous plant highly valued for its culinary importance and nutritional richness. In February 2024, during routine surveillance for diseases in solanaceous crops, a disease with leaf blight symptoms was observed on chilli in a plantation area in Dhubri district of Assam, India. The diseased symptom was characterized by small brown lesions along the leaf margins, which progressively merged into larger necrotic blights causing the leaves to turn brown and wither. The causal organism isolated from the infected plants was identified as Fusarium proliferatum both by morphological and molecular analysis. Koch's postulates also confirmed F. proliferatum to be the causative agent. To best of our knowledge this is the first report of F. proliferatum causing leaf blight disease on chilli (Capsicum annuum) 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.
