Effect of Infrared (I.R.) and Bacillus Cereus on Residual Rate of Insecticide Flash 10% EC

Abstract

This study aimed to test the effect of two factors, biological (Bacillus cereus) and physical (infrared I.R.) in the transformation of the insecticide residue Flash10% EC on wheat plants. Pathogenicity in vitro experiments showed that B. cereus is not pathogenic on wheat seeds. On the other hand, there was no negative effect of the pesticide on bacteria in solid and liquid media, as the number of bacterial colonies in Flash + I.R treatment was 46.56 compared to the control treatment, which was 43.39. As for the field experiments with regard to the pesticide residues in the soil, the results showed that the highest concentration of the pesticide was 12.50 ppm in the treatment of uncultivated soil sprayed with Flash, while the lowest concentration of the pesticide appeared in the soil planted with wheat sprayed with Flash and (IR) + B-bacterium cerus, which was below the level of appreciation. As for the seed treatment, the highest concentration of the active substance 3.10 ppm appeared in the seeds treated with Flash in the absence of other treatments, while the lowest concentration (0.00) ppm appeared in the treatment of seeds treated with Flash treated with infrared (IR).
