Irrigated Rice Research Consortium


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.
