Figure 1:

Biofumigation with Xanthosoma sagittifolium leaves macerates against Meloidogyne enterolobii. These experiments were done by incorporating X. sagittifolium leaves at different concentration (g/45 g) along with M. enterolobii eggs and planting tomato after three days of biofumigation. A: Number of galls. B: Number of eggs. C: Reproduction factor. D: Root weight. The experiments were done twice. Quadratic polynomial regression models, p < 0.01.
