Abstract

Neem oil micro-emulsion showed a significantly superior bioefficacy than its macro-emulsion against Spodoptera litura, Spilarctia obliqua and Euproctis lunata. The IC50 values for inhibiting adult emergence in case of micro- and macro-emulsions were 0.09 and 0.14% against S. litura; 0.07 and 0.10% against S. obliqua and 0.05 and 0.02% against E. lunata. The relative effectiveness of micro- to macro- was 1.5:1.0 0gainst S. litura; 1.4: 1.0 against S. obliqua and 3.9:1 1gainst E. lunata.
