| Abstract:
After unsuccessful attempts to control the Fruitlet Core Rot and Leathery Pocket diseases by direct methods in situ, a 3-year diagnostic survey was launched in Martinique in 1993. The main objective is to identify and classify the climatic, edaphic, biological, and cultural factors associated with the etiology of these diseases. The widest variability of situations is represented by a set of 120 plots split into groups according to planting dates. Detailed information and measurements are recorded from land preparation to harvest. Parameters are chosen according to present knowledge of causal factors and way of infestation. Flowering is induced simultaneously for each sub-group of about 20 plots. Infestation levels are recorded at harvest according to a well defined method. A yield analysis is also conducted using agronomic data collected in the survey. The first results indicate a strong spatial and temporal variability of the diseases, thus validating the methodological options. | |
