Abstract:

Experiments were conducted to evaluate the efficacy of different kind of botanicals and fish oil rosin soap (FORS) against mealy bug, Phenacoccus solenopsis Tinsley (Psuedococcidae: Hemiptera) at laboratory and field condition. Results revealed that application of FORS @ 2.5 per cent, neem oil @ 3 per cent and NSKE @ 5 per cent were found to be the most effective treatments and recorded low mean population of mealy bugs viz., 5.5, 7.5, 9.3 and 5.9, 7.4, 8.0 adults/crawlers per 5 cm apical shoot with the per cent reduction of 85.3, 79.8, 74.9 and 84.0, 79.8, 78.2, respectively in both preliminary and confirmatory field trials. FORS @ 2.5 per cent with increased yield of 61.4 and 68.1 per cent in both preliminary and confirmatory field experiments respectively compared to untreated check.
