Weed management in direct-seeded rice under a long-term conservation agriculture-based rice (Oryza sativa)-wheat (Triticum aestivum) system

The Indian Journal of Agricultural Sciences, 2022
Weeds that occur in repeated flushes pose major challenges to direct-seeded rice (DSR). Zero till (ZT) DSR with crop residue influences weed interference considerably and can be substitutive to resource-intensive puddled transplanted rice (PTR).

Differential Growth Response of Rice Cultivars to Pyrazosulfuron-ethyl.

Journal of Weed Science and Technology, 1995
In growth response to pyrazosulfuron-ethyl [ethyl 5-[[3-(4, 6-dimethoxypyrimidin-2-yl) ureido] sulfonyl]-1 H-1-methylpyrazole-4-carboxylate], indica rice cultivars were more tolerant than japonica cultivars in a manner similar to bensulfuron-methyl [methyl α-[[3-(4, 6-dimethoxy-pyrimidin-2-yl) ureido] sulfonyl]-o-toluate].
