Abstract

This study was carried out at Abu Jarash Farm and Weed Laboratory, Faculty of Agriculture, Damascus University, during 2017 winter to investigate the integrated effect of the non-selective herbicide Glyphosate (360 g/l) (Lancer®) and plant extracts of some weeds: sorghum (Sorghum bicolor L.), alfalfa (Medicago sativa L.) and bermuda grass (Cynodon dactylon L.) by using one third and one fourth of the recommended doses of the herbicide mixed with plant extracts for weed management of plots planted with carrot. The integration between herbicide and plant extracts led to 100% weed control when the herbicide was used at 25% of the recommended dose, and was equally effective to that of the recommended dose. The benefits are cost reduction and decrease of harmful effects of synthetic herbicides to the environment. On the other hand, Sorghum bicolor extract was significantly effective in controlling all tested weed species (82.1% effectiveness on Chenopodium album (most sensitive), plant height of wild barley Hordeum murinum L. was 3.8 cm, dry matter content of 4.96% for purple nutsedge, Cyperus rotundus L. and 6.58% for hairy amaranth, Amaranthus retroflexus L. Keywords: Integration, herbicides, plant extracts, reduced doses, weeds
低剂量草甘膦与植物提取物对胡萝卜杂草综合治理的研究
本研究于2017年冬季在大马士革大学农业学院Abu Jarash农场和杂草实验室进行,旨在研究非选择性除草剂草甘膦(360 g/l) (Lancer®)和一些杂草的植物提取物的综合效应:高粱(sorghum bicolor L.)、紫花苜蓿(Medicago sativa L.)和百慕大草(Cynodon dactylon L.)分别使用推荐剂量的三分之一和四分之一的除草剂与植物提取物混合,用于胡萝卜种植地块的杂草管理。当除草剂用量为推荐剂量的25%时,除草剂与植物提取物的结合可以达到100%的杂草控制效果,并且与推荐剂量的效果相同。其优点是降低了成本,减少了合成除草剂对环境的有害影响。另一方面,高粱双色提取物对所有被试杂草均有显著的防效,其中对藜草(Chenopodium album)的防效率为82.1%(最敏感),对野生大麦Hordeum murinum L.的株高为3.8 cm,对紫苣苔(purple nutgrass)、圆草(Cyperus rotundus L.)的干物质含量为4.96%,对毛苋菜(hairy Amaranthus retroflexus L.)的干物质含量为6.58%。关键词:综合、除草剂、植物提取物、减量、杂草
