| dc.description | A trial was conducted at the Gurabo Substation, Gurabo, Puerto Rico, to evaluate different methods (biological, manual and chemical) for controlling jointvetch (Aeschsynomene sensitiva Sw.) and waterprimrose [Ludgia erecta (L.) H. Hara] in rice. The sequential applications of either propanil [N-(3,4-dichlorophenyl) propanamide] or thiobencarb [S-(4-chlorphenyl) methyl diethylcarbamothioate] as early postemergent, followed by a mixture of 2,4-D [(2,4-dichlorophenoxy) acetic acid] and bentazon [3- (1 -methylethyl)-(1H)-2,1,3-benzothiadiazin-4-(3H)—one 2,2-dioxide] were found to be the two best treatments. Both treatments oufyielded all others except the weeded check. The sequential application of propanil followed by Collego™ (a mycoherbicide) gave only fair weed control and produced a poor yield. | en-US |
| dc.description | Se realizó un experimento con arroz en el cual se evaluaron distintos métodos para desmalezar (biológico, manual y químico), especialmente para combatir el moriviví bobo (Aeschynomene sensitiva) y el clavo acuático (Ludwigia erecta). Con aplicaciones en serie de propanil a razón de 3.36 kg pa./ha a thiobencarb a razón de 4.48 kg ia/ha como posemergente temprano seguidas por una mezcla de 2,4-D a razón de 1.12 kg pa/ha y bentazon a razón de 1.12 kg ia/ha se pudo erradicar excelentemente ambas malezas. En las parcelas tratadas así se logró un mejor rendimiento de arroz que con los demás tratamientos excepto con el testigo desyerbado a mano. | es-ES |
