A total of 452 rice farmers from three main granary areas of Muda Agricultural Development Authority (MADA), Kemubu Agricultural Development Authority (KADA), and Integrated Agricultural Development Area Barat Laut Selangor (IADA BLS) were surveyed in 2019. The goal was to determine farmers’ knowledge of and management practices for weedy rice (Oryza spp.) as well as the adoption level of Clearfield® rice technology (CRT) in Malaysia. Most farmers (74%) were adept at recognizing weedy rice. The majority of farmers (77%) perceived transplanting and water seeding rice systems as the best options to manage weedy rice, while only 10% of the farmers adopted CRT. The low level of adoption of this technology was due to several constraints, including the high cost of the CRT package and occurrence of imidazolinone (IMI)-resistant weedy rice in their farms. Farmers from MADA and IADA BLS reported the occurrence of IMI weedy rice in their farms for more than nine planting seasons, whereas those from KADA reported having resistant weedy rice for five to six planting seasons. The main factor contributing to the evolution of IMI-resistant weedy rice was ignorance about the technology and deliberate disregard of stewardship guidelines. The survey revealed that there is a need to increase awareness about CRT through training and educational programs for proper adoption of this technology.

马来西亚半岛杂草稻 (Oryza spp.) 管理实践和 Clearfield® 稻米技术采用调查

2019 年，共有来自慕达农业发展局 (MADA)、克木布农业发展局 (KADA) 和巴拉劳特雪兰莪综合农业发展区 (IADA BLS) 三个主要粮仓区的 452 名稻农接受了调查。目标是确定农民杂草稻知识与管理实践（稻米spp.) 以及 Clearfield® 水稻技术 (CRT) 在马来西亚的采用水平。大多数农民（74%）善于识别杂草稻米。大多数农民 (77%) 认为移栽和水播水稻系统是管理杂草稻的最佳选择，而只有 10% 的农民采用 CRT。这项技术的采用率低是由于几个限制因素，包括 CRT 包装的高成本和他们农场中出现抗咪唑啉酮 (IMI) 的杂草稻。来自 MADA 和 IADA BLS 的农民报告说，他们的农场在超过 9 个种植季节出现了 IMI 杂草稻，而来自 KADA 的农民报告说在 5 到 6 个种植季节出现抗性杂草稻。导致抗 IMI 杂草稻进化的主要因素是对技术的无知和故意无视管理指南。调查显示，有必要通过培训和教育计划提高对 CRT 的认识，以正确采用该技术。
