Effect of Rice Cultivars and Herbicidal Combinations Integrations on Weeds and Yield of Broadcast-Seeded Rice Productivity and Economic Feasibility [PDF]
Journal of Plant Production, 2018 Nowadays there was an attitude from farmers to grow broadcasted seeded rice as an alternative to transplanted rice due to the scarce and costly labors in rice transplanting, but broadcasted seeded rice suffer severely from weed competition where ...

Comparison of Weed Seedbanks in Different Rice Planting Systems
Agronomy Journal, Volume 109, Issue 2, Page 620-628, March–April 2017., 2017 Core Ideas Weed seedbanks were compared in three rice planting systems: machine‐transplanted rice, water direct‐seeded rice, and dry direct‐seeded rice. Weed seedbanks were mainly distributed in soil within a depth of 10 cm. Dry direct‐seeded rice tended to maintain larger seedbanks of sedges, grasses, and some upland weeds.

Journal of Chemistry, Volume 2013, Issue 1, 2013., 2013 The title compound (C18H13ClF3N3O) were synthesized and recrystallized from CH3OH. The compound was characterized by 1H NMR, MS, HRMS, and X‐ray diffraction. The compound crystallized in the monoclinic space group P2(1)/n with a = 8.2354 (14), b = 12.686 (2), c = 16.633 (3) Å, α = 90, β = 97.951 (3), γ = 90∘, V = 1721.0 (5) Å3, Z = 4, and R = 0.0376 ...

CROSS-RESISTANCE OF RICE FLATSEDGE TO ALS-INHIBITING HERBICIDES [PDF]
Planta Daninha, 2017 Cyperus iria (CYPIR) is one of the main weeds in irrigated rice crops. The intense chemical control with acetolactate synthase (ALS) inhibiting herbicides favors the selection of cross-resistance. This study aimed to evaluate the crossresistance of CYPIR
