| A new philosophy and new formulation of pesticide nanoemulsion abamectin and limonene have been tested for its adult activity against Tetranychus urticae Koch. The presence of abamectin and limonene in the formulation was confirmed by Transmission Electron Microscope and Gas Chromatography-Mass Spectrometer. The dose-response data of T. Urticae indicated that the abamectin and limonene TC was more toxic to the pest than its commercial one. Arranged the toxicity values of some treatment based on LT50 values tested against T. urticae in descending orders as follows abamectin1.8%, nano abamectin TC, nano abamectin 1.8%, and abamectin TC. Nano abamectin TC is the second level but is the lowest dose with high absorption and fast toxicity. It was shown that nano orange oil TC was the most effective essential oil and thymus oil was the least effective oil. LC 50 values were 11.21%, 12.17%, 16.11% and 19.17 % for nano orange oil TC. orange oil 6%, nano orange oil 6%, and orange oil TC respectively after 96hr post-treatment. Time of Absorption on Plant Leaves per minutes was the lowest time in leaves absorption nano orange oil (10.33,15.16,21.14,21.25,23.12,33.09,39.13 and 48.08 respectively) for (nano orange oil TC, nanoabamectin TC, orange oil TC nano orange oi l6% nanoabamectin 1.8% abamectin 1.8% orange oil 6% abamectin TC respectively).nano orange oil was more absorption than orange oil TC by 21%. Our findings indicated that nano shape in TC form and then make pesticide formulation was more effective and more absorption in plant leaves against T. Urticae than abamectin and limonene in normal shape and formulation nano shape conversion. The required concentration for controlling T. Urticae decreased more then. because active ingredients became more speared in formulation This approach might be successful examples for decreasing the resistance of this pest to pesticides and reduce environmental pollution. | ||||
