| dc.description | Two herbicide experiments on rice were conducted at the Gurabo and Lajas Substations in 1979 and 1980. Rice cultivar Brazos was planted in 3.1 x 3.1 m plots. Herbicides butachlor [N-(butoxymethyl)-2-chloro-2' ,6' -diethylacetanilide], oxadiazon [2 tert-butyl-4(2,4-dichloro-s-isopropoxyphenyl)-∆2-1,3,4 oxadiazolin- 5-one] and propanil (3,4-dichloro-propionanilide) alone or in combination were evaluated for weed control and grain yield. Butachlor at 3.36 and 6.72 kg ai/ha; oxadiazon at 1.12 and 2.24 kg ai/ha; and propanil at 3.36, 6.72 and 13.44 kg ai/ha; and their mixtures gave good to excellent weed control. As a group, propanil provided a better safety margin to rice than butachlor and oxadiazon. All propanil-treated plots outyielded those of the other herbicides. | en-US |
| dc.description | En las Subestaciones de Gurabo y Lajas se establecieron experimentos con herbicidas para controlar los yerbajos del arrozal. La variedad Brazos se sembró en parcelas de 3.1 x 3.1 m. Los herbicidas butaclor, oxadiazon y propanil, solos o combinados, se evaluaron en cuanto a control de las malezas y efecto sobre la producción. Los 3 herbicidas y sus mezclas controlaron muy bien las malezas. El propanil proveyó un mayor margen de seguridad al arroz que los demás. En general, todos los tratamientos de propanil produjeron mejores rendimientos que los de butaclor y oxadiazon en ambas localidades. | es-ES |
