Abstract
A PHYSIOLOGICAL disorder of rice known as ‘suffocation disease’ occurs on the poorly drained soils of northeastern Taiwan. The disease, which is characterized by a reddish-brown discoloration of the older leaves, stunted growth, root rot, and low yield, has been attributed to excessive reduction of the soil1,2. As the recommended remedy3 of draining the fields to facilitate oxidation of the soil by atmospheric oxygen is not feasible during the rainy season, chemical retardation of reduction of the soil was investigated in a greenhouse experiment.
