Leguminous Mucuna bracteata DC. ex. Kurz is\u00a0one of the most commonly planted ground covers in\u00a0oil palm plantations. However, under uncontrolled\u00a0conditions, the covers can smother and entangle\u00a0the palms, especially in young immature plantings.\u00a0Efficacy of five major types of herbicides – paraquat\u00a0dichloride (PD), glyphosate isopropylamine (GI),\u00a0metsulfuron methyl (MM), glufosinate ammonium\u00a0(GA), and disodium methyl arsenate (DSMA),\u00a0as well as ammonium chloride with two separate\u00a0spraying volumes and two different spraying\u00a0frequencies, in controlling M. bracteata were\u00a0studied. Variable spraying volume or spray-towet\u00a0method caused higher M. bracteata mortality\u00a0compared to fixed volume spraying. The PD,\u00a0GI+MM mixture and GA were observed to give\u00a0better control of M. bracteata compared to other\u00a0treatments. Multifactorial ANOVA illustrated that\u00a0herbicide, volume and frequency were showing\u00a0significant post-spraying influence on both percent\u00a0of casualty and alive M. bracteata after most of the\u00a0spraying rounds. Interactions between herbicide\u00a0x volume, herbicide x frequency, and herbicide\u00a0x volume x frequency were spotted in a few postspraying\u00a0census. However, there was no interaction\u00a0found in volume x frequency. Results showed that\u00a0spraying with GI+MM mixture could be one of the\u00a0promising herbicide combinations with spray-till-wet\u00a0technique and variable spraying rounds (reapplication\u00a0as M. bracteata covered >, 70%) was\u00a0the most efficient treatment and with reduced effect\u00a0on M. bracteata regeneration.<\/p>\n
Pokok kekacang, Mucuna bracteata DC. ex. Kurz\u00a0merupakan tanaman penutup bumi yang biasa\u00a0ditanam di ladang sawit. Walau bagaimanapun,\u00a0dalam keadaan yang tidak terkawal, tanaman\u00a0penutup bumi ini boleh melitupi dan menjerut\u00a0sawit, terutamanya sawit yang belum matang.\u00a0Kajian ini dijalankan untuk mengetahui\u00a0keberkesanan lima jenis racun rumpai utama dalam\u00a0mengawal M. bracteata – parakuat diklorid (PD),\u00a0glifosat isoproplamin (GI), metsulfuron metil\u00a0(MM), glufosinat ammonium (GA), dan disodium\u00a0metil arsenat (DSMA), serta ammonium klorida\u00a0dengan dua jumlah semburan berasingan dan\u00a0dua frekuensi semburan yang berbeza. Jumlah\u00a0semburan yang berubah atau kaedah semburan\u00a0hingga basah menyebabkan kadar kematian\u00a0M. bracteata lebih tinggi berbanding jumlah\u00a0semburan tetap. PD, campuran GI + MM dan\u00a0GA didapati dapat memberi kawalan yang lebih\u00a0baik terhadap M. bracteata berbanding rawatan\u00a0lain. Multifaktorial ANOVA membuktikan bahawa\u00a0jenis racun, jumlah dan kekerapan semburan\u00a0memberi pengaruh yang signifikan ke atas peratus\u00a0M. bracteata yang hidup dan mati selepas\u00a0pusingan awal semburan. Interaksi antara racun\u00a0rumpai x jumlah racun, racun rumpai x frekuensi\u00a0semburan, dan racun rumpai x jumlah x kekerapan\u00a0telah dikesan dalam beberapa kajian selepas\u00a0semburan awal. Walau bagaimanapun, tidak\u00a0terdapat interaksi di antara jumlah racun rumpai\u00a0x frekuensi semburan. Hasil kajian menunjukkan\u00a0bahawa semburan dengan GI + MM boleh menjadi\u00a0salah satu daripada gabungan racun rumpai yang\u00a0berkesan dengan teknik semburan-hingga-basah dan\u00a0pelbagai pusingan semburan (aplikasi semula bagi\u00a0M. bracteata menutupi >, 70%) adalah rawatan\u00a0yang paling berkesan dan mampu mengurangkan\u00a0pertumbuhan semula M. bracteata.<\/p>\n
