Weedy rice brochure unveiled!
Weedy rice is an important
problem in
rice, particularly in direct-seeded rice
where its management poses a significant challenge. The problem of weedy rice is
recognized by many farmers in countries such as Malaysia, Thailand, and Vietnam,
where large areas of direct-seeded rice are infested. However, in
other countries in Asia, farmers or even researchers and technicians may not be
aware of the potential problems
caused by weedy rice.
To increase awareness on weedy rice, the
Irrigated Rice Research Consortium (IRRC) has been sharing information with
researchers and farmers in Asia. Part of this information campaign is a brochure
entitled Be aware of weedy rice in Asia, which was developed by Azmi bin
Man of the Malaysian Agricultural Research and Development Institute, Malaysia,
and David Johnson, IRRC Labor Productivity Work Group (LPWG) leader.

The brochure describes weedy rice’s
characteristics, the problems it causes, and its preventive measures and
control.
It is now being distributed widely in Asian
countries. During the 2nd International Rice Congress (IRC) in October, 1,000
copies were taken by participants. Dr. Azmi also spoke on weedy rice during the
IRC and at the Asian Pacific Weed Science Society Conference in Vietnam in
November 2005.
In the Philippines, copies of the brochure were
handed out through the Philippine Rice Research Institute, led by program leader
for Unfavorable Rice Environment, Dr. Madonna Casimero. In addition, LPWG’s Joel
Janiya gave out brochures to field technicians and researchers in Iloilo
Province (in the Western Visayas region of the Philippines). He was also
interviewed on a local television channel (Central Philippine University Alumni
Channel, Agritalk Program) on 23 August 2006, introducing the brochure and
discussing the problem of weedy rice and integrated weed management.
In Myanmar, Joel Janiya, together with
collaborator Chit Thein, visited Kyaiklat and Myaung Mya townships, where copies
of the brochure were distributed and explained to farmers.
