Control of witches' broom disease of Cacao in Trinidad



Control of witches' broom disease of Cacao in Trinidad



Trop. Agriculture. Trin., 31: 4, 312-317



The author reviews the various recommendations and tests that have been made from time to time for the control of cacao witches' broom by cutting out diseased material. The recommendations of Baker and Crowdy, which are briefly summarized, still hold good in Trinidad. The figures for pod infection on I.C.S.l from 1943 to 1953 show that in spite of the careful removal of brooms losses remained fairly constant, though much lower than those that might have occurred in the absence of control.
