The PIF method: an agroecological innovation for the plantain Guadeloupean famers?


In the context of agroecological transition, the use of synthetic products is increasingly limited and criticized. Prophylactic measures are presented as a path of investigation. In the French West Indies, particularly marked by the scandal of chlordecone, an insecticide used in the past to control banana weevils, the agroecological sector is looking for more agroecological solutions. Among them, the PIF (Plants Issus de Fragment de tige or ‘Shoots resulting from stem fragment’ in english) method was developed in Cameroon to address the lack of healthy plantain plants and has shown particularly interesting results. The PEYI experimental unit of the INRAE Antilles Guyane center adapted this method to Guadeloupean conditions to enable producers to multiply and sanitize plants on the farm scale autonomously, using agroecological practices. More than three years after the beginning of the project, the method has been adapted to the conditions of the territory, allowing the multiplication of up to 20 times of the number of small plants for a cost of less than 1€60 per plant. The time-consuming nature of the method appeared to be the major obstacle to its adoption and was identified during participatory workshops. To overcome this barrier, organizational innovation has been set up by a farmers’ group and an experiment has been set up in the experimental unit. The objective of the experiment was to identify environmental factors that could improve the method results’ and compensate the time-consuming. Significant results were obtained with the increase of the temperature.
