Esophagogastroduodenoscopy (EGD) is a diagnostic procedure that allows the physician to diagnose and treat problems in the upper gastrointestinal (UGI) tract. The doctor uses a long, flexible, lighted tube called an endoscope. The endoscope is guided through the patient's mouth and throat, then through the esophagus, stomach, and duodenum (first part of the small intestine). The doctor can examine the inside of these organs and detect abnormalities.
Onions are transported in wide-meshed jute fabric or plastic bags, crates, boxes, cartons, baskets or fruit crates. Small-meshed bags are unsuitable for transport due to their low permeability to air.
Root and Bulb Diseases. Some of the diseases that affect the roots and bulbs of onions may start on the foliage and spread downwards and others may carry over into storage. This section will highlight diseases seen primarily on the roots and bulbs.
