Disease damage to rice can greatly impair productivity and sometimes destroy a crop.
Direct losses to disease include reduction in plant stands, lodging, spotted kernels, and fewer and smaller grains per plant and a general reduction in plant efficiency.
Indirect losses include the cost of fungicides used to manage disease, application costs, reduced yields associated with special cultural practices that reduce disease but may not be conducive to producing maximum yields.
Disease control is based on several steps including the correct identification, understanding the disease’s epidemiology, and utilizing host resistance, cultural management, and chemical control.
