Iron Toxicity. Iron toxicity is not a common problem in the field, except in rice crops in Asia (29). It can also occur in pot experiments, and in cases of oversupply of iron salts to ornamental plants such as azaleas. The symptoms in rice, known as ''Akagare I'' or ''bronzing'' in Asia, include small reddish-brown spots on the leaves, which gradually ...
