Wheat and barley are cultivated under a wide range of environments in South Asia, and the climates vary from temperate to tropical. In Southeast Asia, wheat, barley, and triticale are experimental crops. There are a number of rotations involved, as cropping intensities are generally greater than one crop in both South and Southeast Asia. The influence of environment and cropping system has a pronounced effect on soil-borne diseases, with a number of common pre-emergence and post-emergence diseases reported; a few unique soil-borne diseases are found in the more tropical environments. Most of the research on soil-borne diseases has been descriptive; there is relatively little information on either losses or control
