- Abstract
Dose–response experiments were conducted in glasshouse pot experiments to investigate the selectivity of oxadiargyl, a recently introduced herbicide, in direct-seeded rice under both aerobic and anaerobic conditions. Crop sensitivity to oxadiargyl was comparatively greater for wet-seeded (anaerobic) than for dry-seeded rice (aerobic). Likewise, greater efficacy against Echinochloa crus-galli (L.) was also observed under anaerobic conditions. These results indicate greater activity of oxadiargyl under anaerobic conditions, but that application pre-sowing with subsequent flooding would reduce selectivity in wet-seeded rice. The results are discussed in relation to rice production in Mediterranean agriculture.
