Toxic Effect of Capsicum and Garlic Xylene Extracts in Toxicity of Boiled Linseed Oil Formulations against Some Piercing Sucking Cotton Pests

Capsicum and garlic were extracted in xylene. The obtained extracts were used to prepare four emulsifable concentrates "EC's". Formula A "capsicum xylene extract + emulsifier", Formula B "garlic xylene extract + emulsifier", Formula C "capsicum xylene extract in boiled linseed oil + emulsifier" and Formula D "garlic xylene extract in boiled linseed oil + emulsifier ". All prepared formulations passed successfully the physicochemical properties of EC formulation according to WHO. Toxicity of all tested formulations were evaluated against aphid using leaf and slide dipping technique where as formula B, C and D were evaluated against Red mite. The obtained results indicate that all tested formulations had insecticidal activity against tested pests, Formula A and Formula B were highly toxic to aphid and using capsicum and garlic as component in boiled oil formulation increased the effectiveness of boiled oil against the Red mite, this effectiveness depended on component of each formulation, method of treatment and tested pest.
