Abstract:

The practice of fallowing for one year represents a viable alternative to chemical control of Radopholus similis and Pratylenchus coffeae in dessert banana monoculture. Although necessary, fallowing has an economic disadvantage for farmers. The objective of this work is to evaluate the nematicidal and fertilizing effects of lixiviate from banana rachis and Purpureocillium lilacinum in order to reduce the frequency of fallowing. In this study, we performed a chemical analysis of the lixiviate and then compared the two types (plantain lixiviate and dessert lixiviate) at 25% concentration, Bioact (Purpureocillium lilacinum) at 106 spores/ml) and two mixed treatments (plantain lixiviate + Bioact and dessert lixiviate + Bioact) to an untreated control and a reference nematicide, fluopyram at 10% (Verango) during three cycles of cultivation of the dessert banana seedling Grande naine. At the end of each crop cycle, the evolution of the nematode population and the yield of banana plants were evaluated. Chemical analysis revealed a high potassium content in both products and a more remarkable amount of nitrogen in the plantain lixiviate. The results showed that Bioact did not show antagonistic effect against nematodes and impact on production. On the other hand, despite less nematicidal activity, the lixiviate significantly increased the yield compared to the chemical nematicide treatment. Therefore, only in the plots treated with lixiviate, it was possible to carry out several successive crop cycles. This result was more marked with the plantain lixiviate. The results presented in this work are encouraging for the development of biological control methods of banana nematodes by lixiviate.
