abstract
A field experiment was carried out to biointensive management of whiteflies (Bemisia tabaci Gennadius) infesting chilli (Capsicum annuum L.) during rabi season of 2018-19 at Central Experiment Station, Wakawali, Dist- Ratnagiri. During this experiment total six biopesticides tested viz., Metarrhizium anisopliae 2×10⁸ cfu/ml @ 2.5ml/lit, Beauveria bassiana 2×10⁸ cfu/ml @ 5ml/lit, Lecanicillium lecanii 2×10⁸ cfu/ml @ 4ml/lit, Nomuraea rileyi 2×10⁸ cfu/g @ 1g/lit, Bacillus thuringiensis 3.5% ES @ 2ml/lit, Pongamia oil 2% EC @ 10ml/lit, respectively. The results regarding overall mean of three sprays against whiteflies revealed that the treatment Lecanicillium lecanii 2×10⁸ cfu/ml @ 4ml/lit was the best treatment which was recorded minimum (1.49) mean whitefly population per three leaves per plant and was at par with Beauveria bassiana 2×10⁸ cfu/ml @ 5ml/lit (1.55).
