ABSTRACT
A field study was conducted on efficacy of herbal asthras, indigenous plant extracts, bio-pesticides and commercial neem oil against groundnut leaf miner at Main Agricultural Research Station, Raichur during kharif 2010-11. Among biorationals, neem seed kernel extract 5% (NSKE), commercial neem oil and Metarrhizium anisopliae recorded less numbers of larval population during all the periods of observation and were found effective, while, garlic chilli kerosene extract (GCKE) and Nomourea rileyi were found to be least effective. However, profenophos 50 EC a chemical standard check recorded the lowest number of leaf miner larvae and was statistically superior over all other treatments throughout the experimental period. Therefore, biorationals can be well fitted in the IPM package along with other components
Key words :
