Experiment on the influences of cultural practices on the incidence of bunchy top disease and yield of banana was conducted by the Chia-yi Agricultural Experiment Sation, TARI, from 1967 to 1969 at three localities, namely, Lun-Lung, Yung-Hsing and Chun-Kun, in Nantou Hsien where the bunchy top disease often attacked seriously on banana plantations. Seven treatments of, different cultural practices and farm managements were adopted in the experiment as follow:
A. Applying with pig's excreta once two months interval and replanting the diseased plants.
B. Mulching with straws and replanting the diseased plants.
C. Irrigating once two weeks interval during dry season and replanting the diseased plants.
D. Planting cover crop and replanting the diseased plants.
E. Spraying with 800 times of Malathion to kill the vector insect and replanting the diseased plants.
F. No treatment but replanting the diseased plants.
G. Without any treatment as control.
Based on the preliminary results obtained, it was showed significant differences among the various treatments on the infection percentage of bunchy top. All trentments were less infected by the disease than those of control. The irrigation treatment gave the best result on reduction incidence of bunchy top disease. (Table 1). However, there were no significant differences to be found out among the treatments on the plant growth and yield of banana (Table 2).
The losses of yield due to the bunchy top disease were very greatly in each treatment, As it was estimated from the bunch weight and infection percentage of bunchy top, all treatments outyielded from 1.58% to 12.18% than the control one. Moreover, the mulching and irrigating treatment showed the highest yield increased 12.18% and 9.35%, respectively, as compared with the control (Table 3). Therefore, it is important to indicate that the management by holding up soil moisture, such as mulching or irrigating, during the dry season on hillside plantations not only can reduce the percentage of bunchy top disease but also can increased the production of banana. On the other hand, if all diseased plants were destroyed as soon as symptoms appeared, so that they could not be transmitted by banana aphids to healthy plants, the disease could efficiently be reduced the proportions.
