Efficacy of lac based chemicals on egg hatching of root-knot nematode (Meloidogyne incognita) under in vitro condition is reported. Two lac based chemicals viz. 9-hydroxy/2 –nonenoic acid and its methyl ester when evaluated against juveniles (J2) of M. incognita at different concentrations [T1(1000ppm), T2 (500ppm), T3 (250ppm), T4 (125ppm) and T5 (62.5ppm)] showed marked suppression over control. There was a significant difference among the concentrations tested. Highest inhibition of egg hatching (100%) was recorded in T1 with both the chemicals, while other concentrations showed decrease in percentage inhibition of egg hatch with time.
