A field experiment was conducted during the year 2004 at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad to study the impact of organic amendments and biorationals on the natural enemies in soybean ecosystem. Vermicompost @ 2.5 t/ha, combination of vermicompost @ 2.5 t/ha and neem cake @ 250 and 500 kg/ha, combination of Farmyard manure @ 5 t/ha and neem cake @ 250 and 500 kg/ha had no impact on the predators like coccinellids and chrysopids. But among the biorationals, vermiwash recorded significantly higher number of predators three days after spraying. However, the combinations of organic amendments and biorationals involving vermiwash were superior compared to other combinations with the highest number of predators.
