Effects of three different pesticides on free proline content, total soluble proteins and nitrate reductase activity in SO2 fumigated and non-fumigated maize plants (CM-124xCM-128) were studied under pot conditions. Total free proline content reduced in response to all the three pesticides used, while total soluble proteins and nitrate reductase activity increased. Protein content and NRA decreased in SO2 fumigated plants over unfumigated control, while free proline content increased. Pesticide treated plants revealed lesser effect of SO2 fumigation than the untreated plants. Thus pesticides reduced the effect of SO2 fumigation in maize plants.
