Abstract

The results of the effect of three concentrations (1%, 25%, and 50%) and control of each pesticide on the number of bacteria colonies were reported and compared to the control which was 356.9 CFU/gm, with percentage of 100%. The effect of concentrations 1% of Abamectin, Triazophos, and Methomyl on bacteria growth were recorded [234.8 CFU/gm (65.78%), 200.4 CFU/gm (56.1%), and 224.4 CFU/gm (62.8%), respectively].
The effect of concentrations 25% of Abamectin, Triazophos, and Methomyl on bacteria growth were recorded [124.0 CFU/gm (34.7%), 38.2 CFU/gm (10.7%), and 1.9 CFU/gm (0.5%), respectivel], While, the bacterial growth at the concentrations [50% of each of three pesticides was 0.7 CFU/gm (0.19%)] recorded for each tested \pesticide.
