Abstract:

The use of triazole fungicide as agrochemicals into soil leading to many long lasting effects on the microbes present in the soil environment which indirectly affecting the soil health, the current work evaluates the impact of propiconazole on cellulase and invertase activities in red loam soil of groundnut (Arachis hypogaea L.) and paddy soil (Oryza sativa). In vitro experiment was conducted to evaluate the effect of propiconazole on their application rates (1.0, 2.5, 5.0, 7.5 and 10.0 kg/ha) on cellulase and invertase. The period of experimental set up was 10, 20, 30 and 40 days under the in vitro conditions. The results show that propiconazole was found stimulatory for the activities to the cellulase and invertase at lower application rates in both soils after 10 days of incubation period and an outstanding increase in the activity of cellulase and invertase was observed at the application rate 5.0 and 2.5 kg/ha respectively. Conversely, the comparable trend was observed after 20 days of incubation. The higher application rates (7.5 and 10.0 kg/ha) were found toxic to activity of cellulase and invertase in both red loamy and paddy soil. However, the results of the present investigation suggest that, recommended application rates of propiconazole have greater impact on the enzyme activity in the soil and the application of higher doses and regular contact of propiconazole will cause the harmful effect on enzyme activity in red loamy and paddy soil.
