Abstract Bacterial wilt of Capsicum spp. caused by Ralstonia solanacearum species complex (RSSC) is a very disparaging disease and reported to cause complete loss of the crop. The bacterium occurs in the tropical, sub-tropical as well as some of the temperate regions throughout the world. It enters the plant through root wounds or occurs at sites of secondary root emergence and spreads to the plant through the vascular system. The external symptoms of the disease consist of green wilting of the plant and necrosis as well as browning of vascular bundles. The bacterium has a wide host range and can infect 200 plant species belonging to 54 families. It can effectively transmit through soil, seed, roots, insects, contaminated water used for irrigation and also through mechanical injury. The disease is complicated and many cultural, physical, biological and chemical methods have been tried to control it without much success. The use of biological means has proved to be promising to some extent as it is less costly and safe for the environment but for this purpose micro-organisms with strong antagonistic effect on RSSC are required. Considering all the options and their efficacy, the host-plant resistance remains the only prudent option to manage this disease. In this review, an attempt has been made to compile the information about various aspects of bacterial wilt disease in pepper including history, distribution of pathogen, symptoms, detection of the pathogen, host range, transmission, resistance breeding and effective management practices to control the disease.

深入了解辣椒属中的青枯病问题。特别提到印度

摘要辣椒属细菌性枯萎病。由青枯病菌物种复合体 (RSSC) 引起的疾病是一种非常贬义的疾病,据报道会导致作物完全丧失。该细菌存在于世界各地的热带、亚热带以及一些温带地区。它通过根部伤口进入植物或发生在次生根出现的部位,并通过维管系统扩散到植物中。该病的外部症状包括植物的绿色萎蔫和坏死以及维管束褐变。该细菌宿主范围广,可感染54科200多种植物。它可以通过土壤、种子、根、昆虫、用于灌溉的污染水以及机械损伤有效传播。这种疾病很复杂,许多文化、身体、已尝试生物和化学方法来控制它,但没有取得多大成功。生物方法的使用在某种程度上已被证明是有前途的,因为它对环境来说成本较低且安全,但为此目的,需要对 RSSC 具有强拮抗作用的微生物。考虑到所有选择及其功效,宿主植物抗性仍然是控制这种疾病的唯一谨慎选择。在这篇综述中,试图汇编辣椒青枯病的各个方面的信息,包括病史、病原分布、症状、病原检测、寄主范围、传播、抗性育种和有效管理措施,以控制辣椒青枯病的发生。疾病。生物方法的使用在某种程度上已被证明是有前途的,因为它对环境来说成本较低且安全,但为此目的,需要对 RSSC 具有强拮抗作用的微生物。考虑到所有选择及其功效,宿主植物抗性仍然是控制这种疾病的唯一谨慎选择。在这篇综述中,试图汇编辣椒青枯病的各个方面的信息,包括病史、病原分布、症状、病原检测、寄主范围、传播、抗性育种和有效管理措施,以控制辣椒青枯病的发生。疾病。生物方法的使用在某种程度上已被证明是有前途的,因为它对环境来说成本较低且安全,但为此目的,需要对 RSSC 具有强拮抗作用的微生物。考虑到所有选择及其功效,宿主植物抗性仍然是控制这种疾病的唯一谨慎选择。在这篇综述中,试图汇编辣椒青枯病的各个方面的信息,包括病史、病原分布、症状、病原检测、寄主范围、传播、抗性育种和有效管理措施,以控制辣椒青枯病的发生。疾病。考虑到所有选择及其功效,宿主植物抗性仍然是控制这种疾病的唯一谨慎选择。在这篇综述中,试图汇编辣椒青枯病的各个方面的信息,包括病史、病原分布、症状、病原检测、寄主范围、传播、抗性育种和有效管理措施,以控制辣椒青枯病的发生。疾病。考虑到所有选择及其功效,宿主植物抗性仍然是控制这种疾病的唯一谨慎选择。在这篇综述中,试图汇编辣椒青枯病的各个方面的信息,包括病史、病原分布、症状、病原检测、寄主范围、传播、抗性育种和有效管理措施,以控制辣椒青枯病的发生。疾病。
