Effects of metsulphuron-methyl on amylase, invertase and xylanase activities in two soil types.
Effects of metsulphuron-methyl on the activities of amylase, invertase and xylanase in loamy sand and clay were evaluated for up to 28 days under laboratory conditions. Metsulphuron-methyl at 1.0 microg/g caused a significant reduction in amylase, invertase and xylanase activities for the entire period of study, especially at 28 days incubation in both soils. The lowest activities of the three enzymes were observed in the presence of 5.0 microg/g at 28 days incubation.
