The sanitation harvesting included in a coffee berry borer management plan should eliminate almost all residual fruits from branches to be efficient
In a coffee plantation with one annual harvest and a marked dry period, how sanitation harvesting should be done to reduce damages caused by the coffee berry borer (CBB) on the harvest? For two consecutive years, in El Salvador, we measured quantities of attacked and healthy residual fruits in March, as well as attacked and healthy new fruits before the harvest in September, in control plots and in plots with sanitation harvesting. In year 1, the sanitation harvesting was done by a team of farm workers without supervision, in year 2, sanitation harvesting was made by a team supervised by a leader previously trained. None sanitation harvesting had reduced significantly residual berries on ground. Unsupervised sanitation harvesting led to a 65% reduction of residual berries on branches. Supervised sanitation harvesting led to a 93% reduction of residual berries on branches. As a result, unsupervised sanitation harvesting doesn't lead to a significant reduction of infested berries on new harvest. On the contrary, a supervised sanitation harvesting leads to a significant reduction of infested berries on new harvest (70 % infested berries less than control plots). Residual berry from branches seems to influence new harvest attacks and can be eliminated by supervised sanitary harvest. So, the elimination of residual berries, from branches made through a rigorous sanitation harvesting, is a useful contribution to the control of the CBB.
