(CGMMV) is a of economic importance affecting cucurbit crops and Asian cucurbit vegetables. CGMMV was detected in the Northern Territory (NT) in September 2014, the first record for Australia, with 26 properties confirmed as of May 2016. Research was undertaken to determine virus longevity in soils in the NT and investigate the use of disinfectants to remove viable CGMMV from the soil. An in-field trial at 12 months post-quarantine at four properties, and bioassays from collected soils indicate that CGMMV remained viable in at least two of the properties 12 months after plant hosts were removed from the ground. The infectivity of CGMMV from soil was also investigated in two trials with 140 watermelon seeds and 70 watermelon plants sown into CGMMV infested soils with or without the application of the disinfectants Virkon (2%) and Bleach (1%). Watermelons grown in soil, not treated with the Virkon or Bleach, showed CGMMV infection rates of 4% and 2.5% respectively. When Virkon or Bleach was applied, no positive CGMMV detections were observed in the watermelons. This research highlights the importance of proper management of infested properties and the need for on-farm biosecurity to manage CGMMV.
黄瓜绿斑驳花叶病毒（CGMMV）是一种对经济有重要影响的病毒，会感染葫芦科作物和亚洲葫芦科蔬菜。2014年9月在北领地（NT）检测到CGMMV，这是澳大利亚的首次记录，截至2016年5月已有26处被确认。开展了研究以确定北领地土壤中病毒的存活时间，并调查使用消毒剂从土壤中去除活的CGMMV的情况。在四个农场隔离12个月后进行的田间试验以及对采集土壤的生物测定表明，在将植物寄主从地里移除12个月后，至少在两处农场中CGMMV仍具有活性。还通过两项试验研究了土壤中CGMMV的传染性，将140颗西瓜种子和70株西瓜植株播种到受CGMMV侵染的土壤中，其中部分土壤施用了消毒剂卫康（2%）和漂白剂（1%），部分未施用。在未用卫康或漂白剂处理的土壤中种植的西瓜，CGMMV感染率分别为4%和2.5%。当施用卫康或漂白剂时，在西瓜中未检测到阳性的CGMMV。这项研究突出了对受侵染农场进行妥善管理的重要性以及农场生物安全对于管理CGMMV的必要性。
