| The effect of sisal liquid residue (fresh and fermented) was evaluated in controlling the root-knot nematode (Meloidogyne javanica) in tomato plants. Bioassays were conducted in vitro with 100 µL of an aqueous suspension containing 300 juveniles (J2) of M. javanica and 1000 µL of sisal liquid residue. The treatments consisted of nematode immersion for 24 and 48 hours in sisal liquid residue, fresh or fermented, diluted in water to the final concentrations of 0, 2.5, 5, 7.5, 10, 12.5, 15, 17.5 and 20%, and nematicide Carbofuran at 350 mg of the active ingredient per liter. Under greenhouse conditions, 4000 juveniles of M. javanica were inoculated on tomato plants grown in pots, and after one week, 100 mL of sisal liquid residue at concentrations of 0, 4, 8,... |
