Abstract

The mistletoe ( Scurrula ferruginea ), a parasitic plant, is quite widespread in Malaysia. A severe infestation of S. ferruginea was reported on mature hybrid cocoa (9-12-year-old plantings) in a cocoa estate near Merlimau, Malacca in the 1980s. The effect on crop yield was not known, but the vigour, yield and photosynthetic capability had been greatly reduced. The control measures included: (i) removal of infected trees or their infected branches by pruning or poisoning, and (ii) chemical treatments designed to kill the endophytic system. A total of 588 hectares were pruned manually to remove the mistletoes in the cocoa estate near Merlimau, in May/June 1989. The average cost of pruning was estimated at RM 34.50 per hectare. In a poisoning trial using six herbicides (fluroxypyr, triclopyr, dicamba, paraquat, glufosinate-ammonium and 2,4,5-T) the costs was as high as pruning. Manual pruning was therefore the recommended method of controlling cocoa mistletoe. Integrated Weed Management is perhaps the next step towards more effective and more efficient control of mistletoes over very large areas inclusive of cocoa estates, orchards and other agricultural/non-agricultural areas. Keywords: Scurrula ferruginea, mistletoe, parasitic plant, cocoa, management

寄生于可可上的寄生植物锈叶槲寄生及其管理

槲寄生是一种寄生植物，在马来西亚分布很广。据报道，20世纪80年代，马六甲Merlimau附近一个可可庄园的成熟杂交可可(9-12年种植)发生了严重的铁锈病。对作物产量的影响尚不清楚，但大大降低了作物的活力、产量和光合能力。控制措施包括:(i)通过修剪或中毒去除受感染的树木或其受感染的树枝，以及(ii)旨在杀死内生系统的化学处理。1989年5 / 6月，在Merlimau附近的可可庄园，共人工修剪了588公顷的槲寄生。修剪的平均成本估计为每公顷34.50令吉。在使用六种除草剂(氟虫腈、三氯虫、麦草畏、百草枯、草甘膦铵和2,4,5- t)的中毒试验中，成本与修剪一样高。因此，人工修剪是控制可可槲寄生的推荐方法。综合杂草管理可能是在包括可可庄园、果园和其他农业/非农业地区在内的大片地区更有效和更有效地控制槲寄生的下一步。关键词:铁血藤，槲寄生，寄生植物，可可，管理
