dc.description.abstractThe aim of present study is to enhance the stability of physico-chemical characteristics of neem kernel aqueous extract by botanical stabilizer system. There are variety of bioactive constituents are present in neem which give broad-spectrum of insecticidal activity. Neem aqueous extract is commonly used and found very effective in pest control applications without harming the environment. However, due to hydrolytically unstable characteristics of neem active ingredients which results its lesser bioactivity and limits its usage in aqueous form. To overcome this un-stability issue oil extracted botanical stabilizer (Prosopis juliflora) (Junglee kikar)) were used in various ratios. In 70-30 (NKP-KP) composition (NKP- Neem kernel powder; KP- Kiker powder), neem aqueous extract was found stable without any turbidity, pH change, and fungal growth. Active ingredient, Azadirachtin was found stable with very less degradation i.e only 20–30% degradation. This may possibly be due to inhibition of hydrolytic reactions. Bio-efficacy evaluation data also showed improved and stable mosquito larvae mortality per cent i.e 75–90% with 8 µg/g LD50 value. The approach used in this study could be very useful in long term stability of neem kernel extract in various geographical conditions without adding toxic solvents or chemical compositions.en_US
