Abstract:

Large Cardamom is common cultivated spice crop in Nepal as well as in India and Bhutan. Large Cardamom is prone to many diseases, among them viral diseases are annihilative which causes sententious yield loss. Field surveys were conducted during different seasons of 2016-17. Chirke is serious as far as rate of spread is concerned and Foorkey is serious as far as yield loss is concerned. Chirke is caused by Large Cardamom Chirke Virus (LCCV), a new virus species under the genus Macluravirus, family Potyviridae and is characterized by mosaic with pale streak on the leaves. The streaks turn pale brown resulting in drying, withering of leaves and finally death of the plants. The flowering in diseased plants is debased. The chirke disease is transmitted by mechanical sap inoculation and also by aphid (Ropalosiphum maidis Fitch). The cultivar Kopringe is resistant to chirke. Excessive sprouting and formation of bushy dwarf clumps at the base of the mother plants that gradually die, characterize the foorkey disease caused by Cardamom Bushy Dwarf Virus (CBDV). The primary promulgation of the disease from one area to another is through infected rhizomes and further spread within the plantation by aphids, Pentalonia nigronervosa Cog., Micromyzus kalimpongensis (Hemiptera: Aphididae).
