Herbicidal potential of pistia stratiotes on the aquatic weeds in the paddy fields / Norfatin Azlen Johari

The herbicidal potential of the water lettuce (Pistia stratiotes) was examined on the germination and growth of barnyard grass (Echinochloa crus galli) and rice (Oryza sativa) seeds. The aqueous methanol and water extractions obtained from water lettuce were applied on both species of the plants. Bo...
