Abstract
In a laboratory incubation study, application of a commercial formulation of tridemorph to a tropical rice soil under flooded condition significantly stimulated CH 4 production at low levels (5, 10 and 20 μg.g -1 ) but inhibited the process at higher levels of 50 and 100 μg.g -1 . Oxidation of CH 4 , however, was progressively inhibited with increasing concentrations of the fungicide. Increase in CH 4 production in tridemorph-amended soil was attributed to a hastening in the soil reduction, increase in the K 2 SO 4 -extractable C content and an increase in the population of methanogenic bacteria. Inhibitory effect of the fungicide on the oxidation of CH 4 , on the other hand, was related to the inhibition in the population of methanotrophic bacteria.
