We hypothesized that priming pineapple plants could contribute to pest control in a more ecological production system based on rotation with cover crops to benefit from a low initial inoculum (Soler at 2013, a). Here, two examples of present experiments show the potential management of R. reniformis and D. brevipes on the MD2 variety with SAR and ISR induced by appropriate stimulations. The possibility of using them as components of pesticide-free biocontrols is discussed. This is a synthetic presentation of CIRAD's research on this subject; detailed data have recently been published (Soler et al., 2021) or will be published soon, such as during the next ISHS Pineapple Symposium in 2023.
