Summary. Several new herbicides were tested for control of weeds in broadcast‐seeded flooded tropical rice. Among the new herbicides, S‐(2‐methyl‐l‐piperidylcarbonyl‐methyl)‐ O,O ‐di‐ n ‐propyl dithiophosphate (C‐19490), S‐(2‐methyl‐l‐piperidylcarbonyl‐methyl)‐ O,O ‐di‐ n ‐propyl dithiophosphate combined with 2‐(1′,2′‐dimethylpropylamino)‐4‐ethylamino‐6‐methylmercapto‐ s ‐triazine [C‐19490/C‐18898 (C‐288)], and N ‐secondary‐butyl‐4‐tertiary‐butyl‐2,6‐dinitroaniline (A‐820) were highly selective in controlling Echinochloa crus‐galli (barnyard grass) and other annual weeds under tropical conditions. S‐(4‐chlorobenzyl)‐ N,N ‐diethylthiol carbamate (benthiocarb) and N ‐(butoxymethyl)‐2‐chloro‐2′,6′‐diethylacetanilide (butachlor) continued to look promising in our experiments. Only butachlor is widely used in Asia. Désherbage chimique des cultures tropicales de riz inorndé, seméà la volée
