It can live in the roots of the rice plant without showing any symptoms and during the booting stage it grows on its stems and leaves. This disease is transmitted through the seeds, flowers, leaves and residue of crops. Lesions caused by different insects and other conditions that put strain on the plant enable the organism to penetrate more easily it may also invade the plant through the hydathodes which are the stomas located on the underside and the edges of the leaves. This is a disease that causes rice grain and plantlet rotting caused by the Burkholseria glumae that inhabits the soil and which can live in tomato, pepper, eggplant, Chinese basil and sesame crops as well as other weeds associated with rice fields. ![]() Product Development Manager, Sumitomo Chemical Latin America National Autonomous Agricultural Research Institute (INIAP) - Ecuador During 2005 rice crops in Panama reported a 40% loss caused by this disease.Actualmente es limitante económicamente en Colombia, Nicaragua, Venezuela, Costa Rica, Panamá y República Dominicana.In 2011 the presence of this plague was declared a sanitary emergency in Colombia, a status that was extended until June of 2012, jeopardizing close to 500 thousand hectares of cultivated land.It is currently causing economic limitations in Colombia, Nicaragua, Venezuela, Costa Rica, Panama and the Dominican Republic. This bacterium has been reported and confirmed to be found in fields across China, Korea, India, Philippines, Thailand and the United States.Fields that have been severely affected show a yield loss of more than 75%. It causes grains and plantlets to rot.The production of rice, one of the basic grains currently feeding almost half of the world’s population is being threatened by this disease.Bacterial Panicle Blight, the disease with the greatest impact on rice cropsīacterial panicle blight (Donald Groth, 2011 and Cristo Pérez, 2011)
