The rice crop (Oryza sativa) and its major phytosanitary problems: A focus on the Gharb region
Rice (Oryza sativa) is the staple food of more than half of the world's population. Its production is confronted with several biotic constraints. As a matter of fact, rice blast (Pyricularia oryzae) and brown spot of rice (Helminthosporium oryzae), weeds, and granivorous birds have negative imp...
