Curvularia eragrostidis, a new threat to large cardamom (Amomum subulatum Roxb.) causing leaf blight in Sikkim

An in-vitro experiment was carried out for testing the efficacy of various fungicides by adopting poisoned bait method against Rhizoctonia solani (isolated from large cardamom) in Agricultural Research Station, Pakhribas. The experiments were conducted with Completely Randomized Design (CRD) during 2016 with four replications. Two level of concentration of the fungicides (10 ppm and 100 ppm) were used and concentration was calculated based on active ingredients (a.i.) of the pesticides. At lower concentration (10 ppm), Nativo (Tubeconazole 50% + Trifloxystrobin 25 WG) and Dhanustan (Carbendazim 50 % WP) whereas at higher concentration (100 ppm), Folicure (Tubeconazole 25.9 %) and Saaf (Carbendazim 12 % + Mancozeb 63 % WP) found effective for the inhibitions of mycelia growth of R. solani. For the control of R. solani, Nativo and Dhanustan showed greatest inhibition of mycelia growth at 10 ppm concentration as compared to other fungicides. The fungicides containing Tubeconazole and Carbendazim as active ingredients, shows highest degree of mycelia inhibitions as compared to others. The fungicides found effective for inhibition of mycelia growth of R. solani in this study should be further tested in field conditions to verify their efficacy as well as to determine their optimum doses of application.

Large Cardamom

Large Cardamom (Amomum subulatum Roxb.) is one of the most valuable cash crop of the Himalayan mountain region including Nepal, India, and Bhutan. Nepal is the world’s largest producer of the crop while the Taplejung district contributes a 30%–40% share in Nepal’s total production. Large cardamom is an herbaceous perennial crop usually grown under the shade of the Uttis tree in very specialized bioclimatic conditions. In recent years, a decline in cardamom production has been observed which is being attributed to climate-related indicators. To understand the current dynamics of this under-canopy herbaceous crop distribution and its future potential under climate change, a combination of modelling, remote sensing, and expert knowledge is applied for the assessment. The results suggest that currently, Uttis tree cover is 10,735 ha in the district, while 50% (5198 ha) of this cover has a large cardamom crop underneath. When existing cultivation is compared with modelled suitable areas, it is observed that the cultivatable area has not yet reached its full potential. In a future climate scenario, the current habitat will be negatively affected, where mid elevations will remain stable while lower and higher elevation will become infeasible for the crop. Future changes are closely related to temperature and precipitation which are steadily changing in Nepal over time.

Large Cardamom

Large cardamom is the major spices crop and an export potential high value crop. Nepal is the largest producer of large cardamom. The review study focuses on the status of the production, marketing, exports and constraints in the large cardamom cultivation in Nepal. The production of the large cardamom is found to be increasing but the productivity was in decreasing trend. The varieties are under the process of registration. The most of the marketing channel is the exporting channel and India is the primary market of export. Some of the value addition processes are missing during processing of the crop. Price volatility and lack of proper technical knowledge are the major constraints observed in the production and trade. Other problems like improper planting material, traditional curing process, susceptible to viral diseases, high custom tariffs and trade taxes in some countries are also the observed problems. Producing of the product with quality standard through technical training and workshop from public and private sector can help in uplifting the large cardamom status of the country.
