Silicon is the main objective of many researchers whose goal is to see its use as an inductor resistance. The action of the inductor happens in the plants, where it does not affect the pathogen directly, but the effect will contribute for its control. Therefore, the main objective of this report was to evaluate the effect of silicon on the embryonic development and the hatching of Meloidogyne javanica. For this, three sources of silicon (Silifort ® , Rocksil ® and wollastonite) in the dosage 0 (distilled water), ½, 1 and 2x the producer indication, resulting in a factorial 3 x 4, were evaluated in two different times. In Petri dishes were add 1 ml of suspension with 1500 eggs, and eventually juveniles of M. javanica, and 9 ml of treatment, which were evaluated, in Peters chambers, the percentage of eggs one, two, tetra and multicellular, eggs containing juvenile formed, and the hatched in a period of three days and seven days after the incubation (DAI). The wollastonite had stimulated the embryonic developments, as the increase of the dosage, were not seen with the Silifort ® and Rocksil ® experiments. The increase in the dosage of wollastonite caused stimulus to the hatching in 3 DAI, while Silifort ® caused the reduction of hatching in 3 DAI in both experiments. In 7 DAI, there was a reduction of hatching of juveniles exposed to Silifort ® and Rocksil ® , in the experiments 1 and 2, respectively.
