BOTRYODIPLODIA STEM END ROT OF MANGO AND ITS CONTROL |
| Author: | S. Sangchote |
| Abstract:
Botryodiplodia theobromae, the causal organism of stem end rot disease of mango was studied. Isolates of B. theobromae obtained from different sources induced different levels of disease on mango. An isolate from a mango affected by stem end rot was most virulent. Of six mango cultivars tested, cv. Okrong was the most susceptible to B. theobromae. Length of pedicel also affected disease development. Disease development on fruit with long pedicels was slower than on fruit with short pedicels. Immersion of infected fruit in benomyl (500 ppm) at 52°C for 5 min. provided the most effective control Control measures were most effective on fruit inoculated 3 h or 6 h previously using a benomyl suspension prepared 3 h previously. | |
