The practice of imidazolinone-resistant rice production in the irrigated rice fields of Kg Sungai Leman

Rice is an important crop and a staple food in Malaysia. Herbicides are used extensively to control weeds, which represent a major constraint to yield production. Although the introduction of Imidazolinone-resistant Rice with its management system (IRPS) has greatly improved both yields...
