Risk Assessment of Sulfonylurea Herbicides Based on a Complex Bioindicator

The increasing use of herbicides in recent years for improved crop yields requires a risk assessment. To assess their impact on soil, the an indicator named synthetic biological (ISB%) is proposed, which includes range biotic and enzymatic parameters derived from previous experiments. Three sulfonylurea were evaluated, chlorsulfuron, amidosulfuron, tifensulfuron. monitored using different herbicide doses field laboratory Calculating this all experimental variants showed that analyzed was insignificant, but there statistically significant differences between conditions. registration based legislation countries several toxicity tests active substance’s effects against soil microorganisms some functions performed by microorganisms, are also included (ISB). This has capacity to provide important information sustainable management, including minimum set parameters, can global regarding environment, showing changes multiple areas interest, be applied at minimal cost worldwide. In conclusion, we say highlights caused various chemical treatments because it follows variation large number unlike other indicators follow only one, providing useful farming practices.
