- Abstract
- The effect of two fungicides, propiconazole and chlorothalonil on the protease and urease activity were studied in two groundnut (Arachis hypogaea L.) soils. The activity of urease, in terms of ammonia formed from urea was more pronounced in soil samples treated with 5.0 kg ha-1 of the propiconazole and chlorothalonil in both laterite and vertisol soils. Similarly, the activity of protease, (in terms of tyrosine equivalents formed from casein) was enhanced more in soil samples, treated with 5.0 kg ha-1 of the propiconazole and chlorothalonil, but higher concentrations of 7.5 and 10 kg ha-1 of these fungicides were toxic to urease and protease activity in both soils. The activity of urease and protease was decreased gradually on prolonged period of incubation up to 30 and 40 days.
