Diseases of Pepper and their Management

Chapter

Abstract

Diseases of pepper caused by biotic (infectious) and abiotic (non-infectious) agents interfere with the production of pepper. Biotic agents of disease of pepper include fungi, bacteria, nematodes, and viruses. Abiotic disorders include a number of unfavorable cultural or climatic conditions, such as sunlight, nutrient deficiency, and temperature excesses. Diseases affect all parts of the pepper plant including the foliage, stems, roots, fruit, and young seedlings. Fungi and bacteria cause a variety of symptoms such as leaf and fruit spotting, wilting and plant death. Typical symptoms of viral infections are stunting, mottling of foliage and fruit, and small, misshapen fruit. Abiotic disorders such as sunscalding or blossom end rot greatly interfere with the fruit quality and reduces yield. Management of diseases begins prior to planting of the crop and many techniques are used to minimize losses due to disease problems. Control methods include, but are not limited to, the use of cultivars with resistance to diseases, pathogen-free seeds, sterilized equipment for transplant production, rouging and eradication of diseased plants and alternative hosts, field sites that are pathogen-free and isolated from other solanaceous crops, soil fumigation, and application of pesticides and other disease-suppression compounds. Post-harvest disease management techniques include growing healthy pepper plants to produce fruits free from predisposing injuries, using field sanitation practices, avoiding the wounding of fruit, and storing of fruit under optimum environmental conditions.
