Effects of dimethomorph on some enzymatic activities in soil
In this study, soil samples (0-20 cm depth)were taken from the same test fields of Henan Institute of Science and Technology in order to determine the effects of dimethomorph on enzymes activities of soils. Basal soil catalase activity (CA) and urease (UA) enzyme activities, the results showed that high dose of dimethomorph introduced into soil had an significant effect on soil enzymatic activities, the degree of inhibition or promotion of enzymatic activities was not only related to the concentration of dimethomorph, but also to the remain time. Compared with the control, dimethomorph stimulated soil catalase and the action increased with the increasement of treatment concentration; the activity of urease treated by dimethomorph dropped down at first and then rose slowly.
