This publication describes the major rice diseases in the southern United States rice-growing region. Detailed color images of bacterial panicle blight, blast, grain smuts, narrow brown leaf spot, sheath blight, sheath rot, stem rot, water mold and stem rot are included.
Rice diseases pose a major threat to rice production. The two major diseases, sheath blight and blast, cause significant yield and quality reductions that cost farmers millions of dollars each year.
The threat of Cercospora will remain a slight possibility for the 2009 crop, even though it hasn’t been a widespread problem since 2006, according to Dr. Don Groth, LSU AgCenter pathologist at the Rice Research Station.
(Distributed 12/14/06) Developing disease-resistant varieties is the best approach to help farmers fight diseases that afflict rice, said Dr. Don Groth, LSU AgCenter plant pathologist at the Rice Research Station in Crowley.
Diseases Cause Millions in Crop Damage; Scientist Looking for New Ways to Fight Them
(Distributed 06/11/04) Dr. Don Groth held up a Petri dish containing a few spots of a dark mold, and then posed a question. "You wouldn’t think that would cause $10 million to $20 million worth of damage a year, would you?" asked Groth, a plant pathologist at the LSU AgCenter’s Rice Research Station near Crowley.
2011 recommendations for rice varieties and management tips for them. Decisions about rice varieties are some of the most critical you will make, and those deicisions have to be made early each year. The information in this publication will help you decide which rice varieties are best suited to your particular growing conditions. (PDF Format Only)
The objective of the Rice Pathology Project is to develop an integrated disease management program that effectively and economically reduces rice diseases. This project is headed by Dr. Don Groth.
This guide for 2011 contains suggestions for management of the most important or more prevalent diseases of Louisiana plants. It includes information on fungicides, bactericides and nematicides, as well as safety precautions for using them.
