The material explains how to recognize disease patterns in leaves, stems, joint areas, and developing grain, and links disease severity to conditions such as excess nitrogen, insufficient sunlight, heavy rainfall, soil acidity, and nutrient imbalance. It also emphasizes prevention strategies, including selecting resistant rice varieties, improving soil conditions, and applying appropriate seed treatment and disease management steps.","Rice Paddy Book 4  \nProblems with Diseases  \nlevel: advanced  \nEnglish Agriculture  \nRice Paddy Book 4  \nProblems with Diseases  \nAdapted from Ini Sa Ukit Ta Egbael Basakan © 1993, SIL Philippines and is shared under a CC:BY-NC (4 .0) licence.  \nIllustrations are from the collection of the International Rice Research Institute (IRRI), Los Baños, Laguna, Philippines © IRRI 1993.

The International Rice Research Institute gives more information at:  \n[http://www.knowledgebank.irri.org/training/fact](http://www.knowledgebank.irri.org/training/fact)  \nsheets/pest-management/diseases  \nWe hope you enjoy using this Shell Book . Please delete these notes before printing  \nRice Paddy  \nBook 4: Problems with Diseases  \nThere are three other books in the series; they are listed on the Title Page. They will all give you ideas and general guidance, but there are so many variables when growing rice, that you should always consult your local agricultural expert. He will be able to give advice about local conditions and how to vary, when necessary, what is written in these books.  \nAdvice and books on the subject are available from The International Rice Research Institute,  \nDAPO Box 7777, Metro Manila 1301, Philippines and from their website  \n[http://www.irri.org](http://www.irri.org)  \nThis book tells you about various diseases that rice can have, and how to cure them.  \nSee more of the IRRI’s advice on how to manage diseases at:  \n[http://www.knowledgebank.irri.org/training/fact](http://www.knowledgebank.irri.org/training/fact)  \nsheets/pest-management/diseases  \nBlast  \nThe diagram shows the signs of the d","cbCaiouZbxLN9jzD","https://ap.wps.com/l/cbCaiouZbxLN9jzD","pdf",359933,4,1,21,"English","en",105,"# Rice diseases overview\n## Blast\n## Sheath Blight\n## Brown Spot\n## Narrow Brown Spot","[{\"question\":\"How can blast be identified in rice plants?\",\"answer\":\"Blast creates small coffee-coloured leaf patches with grey centers and can darken and snap the stem near the flag leaf.
