Abstract
Physiological responses ofAchlya proliferoides, Saprolegnia ferax andDictyuchus sterilis as affected by the fungicide chlorothalonil (Bravo) were determined. Glucose consumption differed in dependence on the organisms used. Ammonia and peptide nitrogen secretion were stimulated inS. ferax but inhibited in the other two organisms. All doses of the fungicide used decreased phosphorus absorption and increased acid phosphatase activity. The lowest concentrations (30 ppm) of the fungicide increased DNA, RNA and protein synthesis while inhibition was observed at moderate or high concentrations. Aspartate aminotransferase and alanine aminotransferase activities were inhibited inA. proliferoides, stimulated inS. ferax but remained similar to that of the control inD. sterilis.
