摘要：

Use of synthetic pesticides has resulted into health hazards, ecological imbalance, resistance in pests and environmental pollution. ([1]) Neem oil is natural pesticide and has excellent insecticidal properties. Hence, attempts are being made to develop neem oil emulsions to be used as pesticide. Surfactants like castor-oil based, nonyl phenol-based, sodium lauryl sulphate, and calcium alkyl benzene sulphonate were tried to develop stable emulsions. Neem extract based emulsifiable concentrates were prepared by using methanol. Stability of emulsion as a function of type of surfactants, hydrophile-lipophile balance (HLB) of surfactants and hardness of water was studied. Larvasidal effects of emulsions and emulsifiable concentrates were examined. Laboratory experiments have shown effectiveness of these emulsions and emulsifiable concentrates as pesticide.
