In Martinique or La Réunion, French authorities recently banned the use of pesticides for the management of “soil-borne pathogens” on pineapple after several decades of intensive monoculture where the natural balance between beneficial and harmful communities of soil organisms has disappeared. Today, increasing infestation of pineapple by the nemat...

Monoculture and intensive use of pesticides have reduced the biodiversity of agrosystems and increased the imbalance between pathogenic and beneficial organisms. In the past, pineapple pests were generally controlled by pesticides, but today very few pesticides are authorized. In fragile environments like in the French Antilles, there is a growing...

This study highlights some of the effects of the application of Azotobacter chroococcum (INIFAT5 strain) on in vitro-pineapple plantlets during acclimatization. The bacteria were sprayed immediately after transplanting to the ex vitro environment; the plants were then sprayed every 4 week. Subsequently (4 months) the evaluated variables included pl...

Under the new European regulations, tropical crop infestation by soil borne parasites (Rotylenchulus reniformis for pineapple and Pratylenchus coffeae for banana) cannot be controlled through the use of pesticides, in French Antillas. Therefore, we investigated the possible contribution of induced systemic resistances (ISR) to biocontrol pests and...

Pineapple is one of the most important tropical fruits, but the availability of planting material is insufficient to agricultural demands. Therefore, several pineapple micropropagation protocols have been developed. However, acclimatization of in vitro plants continues to take a prolonged period. Biofertilizers have been found as safe alternatives...

The aim of this study was to evaluate the effect of arginine on sugarcane (Saccharum sp.) somatic embryogenesis, free polyamines and other nitrogenous compounds contents. Segments of leaves were used as explants to establish embryogenic cultures on media with 0 and 50.0mgl−1 arginine. Somatic embryos formation and free polyamines, free proline and...
