| Popis: | The effect of Trichoderma spp., strains PB17 and B23, Paecilomyces lilacinus UNA strain, and nematicide injecting into the pseudostem, on nematode control and banana (Musa AAA) production was evaluated. A commercial banana farm infested with nematodes and planted with the cultivar Grande Naine was selected. A randomized complete block design with 6 replications was used. Monthly applications at 1 * 109 cfu.ml-1 of each strain were made during 20 months. Chemical nematicide application on the soil surface was made every 4 months and injection of oxamyl into the pseudostem was performed every 3 months. Root samples were taken every month in each replicate, for nematode analysis. It was not possible to reduce nematode populations on plants treated with P. lilacinus UNA strain nor with Trichoderma spp. PB17 and B23 strains. However, plants treated with these strains showed higher bunch weight (p=0.0375) and girth (p=0.0402) of the mother plant, when compared with plants without such application. The plants injected with oxamyl and those treated with the rotation of nematicides on the soil surface showed a higher percentage of functional roots (p |
