Project Information

Reference Number 19970078
Project Title Evaluation of Different Formulations of a Fungus Indigenous to the Philippines, Bipolaris sacchari, for control of weedy Echinochloa species in rice
Project Type Contained Use (Screenhouse)
Status N/A
Name of Institution International Rice Research Institute (IRRI), Los Baños, Laguna
Cooperating Institution Ciba- Geigy Limited, Basle, Switzerland
Supervising IBC IRRI-IBC
Project Leader(s) Paul S. Teng, Plant Pathologist
Experimental Facility/Site IRRI, Philippines
Purpose / Objectives 1. To determine the level of control of Echinochloa achieved with the pathogen Bipolaris sacchari applied in transplanted rice in the field in the Philippines.
2. To evaluate the effect of formulation and water management upon herbicidal activity and rice tolerance of Bipolaris sacchari.
3. To compare results obtained in Malaysia and Indonesia with those obtained in the Philippines.
Biosafety measures 1. Trial will be conducted within a screen house on the IRRI site.

2. Standard land preparation will result in natural decomposition of crop residues.

Subject Request of Dr. F. A. Bernardo to import Bipolaris sacchari
Requesting Party Dr. F. A. Bernardo, Deputy Director General for International Services, IRRI
Action of NCBP Approved for implementation

NCBP informed Dr. F. A. Bernardo through letter dated 13 June 1997 that importation of formulations of Bipolaris sacchari do not need approval/endorsement of the NCBP considering that Bipolaris Sacchari was isolated from a fungus indigenous to the Phil. and therefore, is not considered regulated material under the Phil. Biosafety Guidelines.
