It explains how key insects such as stem-borers, grasshoppers, maggots, and cutworms damage rice, including how their life cycles affect plant parts and yield. Advice emphasizes using treatments only when necessary, managing risk with appropriate fertilizer use, and considering natural alternatives to pesticides while seeking local expert recommendations for local conditions.","Rice Paddy Book 3  \nProblems with Pests  \nlevel: advanced  \nEnglish Agriculture  \nRice Paddy  \nBook 3  \nProblems with Pests  \nAdapted from Ini Sa Ukit Ta Egbael Basakan © 1993, SIL Philippines  \nand 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.

Please change these forms to local male or female names.  \nYou can also substitute local names for plants, medicines, vaccines, food, tools, animals or any other item.  \nIf you can, ask a local medical or nutritional expert to verify the advice given in a booklet, if appropriate.  \nYou can change the text as you desire and you can also change any of the illustrations if you need to.  \nWhen you print the book it will be A5 size, each page on a separate sheet. If you want to make it into an A5-sized booklet, Word can do this automatically for you. You should:  \n• Go to “File”  \n• Select “Print”  \n• click on “Page Setup”  \n• From the “multiple pages” drop-down box, select“Book fold”.  \n• Click “ok”. The book should now print as a booklet for you. If you do not have a printer which will print automatically on both sides of the paper, you will need to turn the paper over manually when prompted.  \nNote: This book recommends the use of pesticides to manage pests that damage rice at various phases during its growth. The International Rice Research Institute also has advice about natural alternatives to manage pests. See  \n[http://www.knowledgebank.irri.org/training/fact](http://www.knowledgebank.irri.org/training/fact)sheets/pest-management for more information.  \nWe hope you enjoy using this Shell Book . Please delete these notes before printing  \nRice Paddy Book 3: Problems with Pests  \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 (IRRI), DAPO Box 7777, Metro Manila 1301, Philippines  \nand from their website [http://www.irri.org](http://www.irri.org)  \nIf you want to earn a good profit from rice, you must kill any pests. But do not spend more money than the profit you will earn! Only treat the pests when it is necessary. And when you are sure about it. Also, get advice about natural alternatives to pesticides. Natural methods may be safer and cheaper.
