On farm selection for witches' broom resistance in Bahia, Brazil- a historical retrospective
Witches' broom, caused by Crinipellis perniciosa, was introduced in Bahia in 1989, causing severe economical, social and ecological losses. Since the beginning, resistance was chosen as one of the key points of the integrated pest management adopted by the Cacao Research Center (CEPEC). Today, 14 years after the begining of the program, more than one thousand trees were pre-selected by CEPEC and more than five thousands pre-selected by farmers. Among these, highly productive and resistant clones have been found. In this paper, we report the strategies adopted, the results and some drawbacks on that program.
