Abstract :
The paraffinic fraction and nonionic surfactant increased the efficiency of the potassium salts of fatty acids concentrate (M-pede 49% EC) insecticide/ miticide against aphids (Aphis fabae), red mite (Tetranychus urticae) and whitefly (Bemisia tabaci) by 7.36, 12.67 and 10.97 folds respectively. The obtained results also indicate that the addition of a mixture of 4% paraffin and 3% surfactant to neem oil EC (Triology 90% EC), gave the highest values of relative toxicity, whereas it showed 9.55, 1.82 and 38.29 folds against aphids, red mite and white fly, respectively. It should therefore be possible to optimize and maximize the pesticidal activity of fatty acid-based and neem oil products by using appropriate paraffinic fraction and/or nonionic surfactants to be applied as ready-to-use formulations.
