| Abstract | Enset (Ensete ventricosum Welw. Cheesman) production and productivity in Ojojia water shade is strictly affected by disease and insect pests this leads, a serious devastating cultivar diversity and yield losses. The objectives of the study were to assess the major disease and pest in Ojojia water shade based on farmers’ perceived constraints, to analyze farmers’ traditional knowledge on management of disease and pests in the area, to access the susceptible and resistance enset cultivar to insect pests in the water shade and grouping of cultivars with their similarity for disease and insect pests. One hundred eighty households from three villages, among those who own enset crop were selected based on purposive systematic sampling technique. Based on farmers, assessment, a total of 29 different enset cultivars were identified and submitted to further disease and insect pest evaluation. The results indicated that enset disease and pests are the second most important production constraints in the area. Of which, enset bacterial wilt, mealy bugs, nematodes, worm, termite and root rot were the most signaled. Moreover, cutting knife, sharing planting material, use of the same farm equipment, climate change, flooding, animal attack and wind movement were the main cause of disease in the area. Based on cluster and principal component analysis pointed out the existence of five clusters with different in sizes based on similarity of cultivars. Cluster I consisted the maximum number of cultivars accounting for about 48.27% of the total cultivars from the water shade. Cultivars in this cluster were mainly identified by 85% of similarity and susceptible to enset bacterial wilt, mealy bugs and nematodes. Conversely, cultivars fall in to this cluster are highly resistant to disease and insect pests particularly for root rot, worm and termites. Cluster II had of six (20.69%) cultivars and had 60% similarity and susceptible to most of identified disease and insect. Cluster V had only two (6.89%) cultivars and had medium resistant to most of the disease and insect pests. All other clusters have much susceptible to almost all disease and insect pests. The result of principal component analysis clearly showed that diseases and pests were the most important constraints to enset production in the water shade. The first two principal component scores 69.90% (PCA-1) and 17.60% (PCA-2) showed a lucid interaction between enset cultivars and major disease and pests. Bacterial wilts, root rot and nematodes, were the most economical important disease and pests for enset cultivars in the area. Therefore, need strong attention on the management and conservation of enset cultivars before complete loss. |
