A handbbok on Weed Control in Rice.pdf

Foreword
Farmers everywhere search for ways to widen the narrow margin of profit
between production costs and crop returns. Weeds cause more yield losses in
ricefields than any other pest. Cost-effective methods for controlling weeds
could help preserve profits and increase yields.
The authors have designed this book to provide practical information on
controlling weeds in the many different rice cultural systems, using an inte-
grated management approach. It is exceptionally comprehensive, and can be
used as a textbook, as a field guide, and as a manual for making decisions in
crop management.
The handbook has been especially designed to facilitate inexpensive trans-
lation and copublication. Contact Communication and Publications Services,
IRRI Information Center, for permission and assistance, at no charge, in any
activities to extend its benefits to rice workers who read languages other than
English.
