Witches' broom disease investigations. III. Notes on the occurrence of witches' broom disease



Witches' broom disease investigations. III. Notes on the occurrence of witches' broom disease



Trop. Agriculture, Trin, 20: 5-12. bibl. 1



The observations were recorded on 76 cacao trees situated at River Estate, Trinidad. In the 3 years the disease spread very rapidly but probably had not reached its maximum intensity. Trees producing many brooms one year are likely to do so the next, trees producing only a few brooms produce only a few in the following year. This applies to both fan and cushion brooms. Cushion broom numbers and flower production are closely correlated but apparently not fan broom and leaf flushes.
