“…In our study, we found that in the plots that were given a single application of oxadiazon, weed density was 32e52% higher than in the plots treated with oxadiazon fb bispyribacsodium fb fenoxaprop þ ethoxysulfuron, which indicates that the application of only PRE herbicides is not enough to provide sufficient weed control in DSR systems. These results are also supported by a previous study in which the application of oxadiazon alone provided 60e75% weed control compared with a weed-free treatment (Ishaya et al, 2007).…”

Dry-seeded rice production systems are increasing in many Asian countries because of labor and water scarcities. However, weeds are the main biological constraints in these systems. Herbicides are widely used to manage weeds but they do not provide effective weed control. The use of crop residue as mulch can suppress weed emergence and weed biomass but mulch alone does not provide effective weed control. The integrated use of herbicide and mulch, however, could provide more effective and sustainable weed control in dry-seeded rice systems. A study was conducted in two consecutive rice growing seasons to evaluate the combined effect of herbicide (treated and nontreated) and rice straw mulch (0, 2, and 4 t·ha −1 ) on weed growth and rice yield in a dry-seeded rice system. In the nontreated plots, weed biomass decreased with increases in mulch amounts, whereas weed biomass in the herbicide-treated plots was similar at different mulch amounts. Overall, herbicide treatments provided better weed control than the mulch treatments. In the nontreated plots, grain yield was similar at different mulch amounts, whereas grain yield in the herbicide-treated plots was greater when the field was mulched with 4 t·ha −1 of rice straw than with no mulch or mulched with only 2 t·ha −1 of rice straw. The results suggest that integrated use of mulch and herbicides can help weed control and increase crop yield in dry-seeded rice.

“…The overall efficacy of pre-emergence herbicides can vary from product to product and environmental conditions can also affect the efficacy (Chauhan and Abugho, 2013;Mahajan and Chauhan, 2013). Among the preemergence herbicides used in DSR systems, oxadiazon was superior as it effectively controlled annual grasses and broadleaf weeds Chauhan and Johnson, 2011b;Chauhan and Opeña, 2013;Ishaya et al, 2007). Although pre-emergence herbicides are essential in DSR systems, they have some limitations such as a narrow application timing, requirement for a critical soil moisture level, and possible phytotoxicity to rice (Baloch et al, 2005;Pellerin and Webster, 2004).…”
