摘  要:
宽叶酢浆草为近年来入侵云南耕地和园林的重要检疫性杂草。为筛选出防除玉米地宽叶酢浆草的最佳除草剂种类,使用7种玉米地阔叶杂草防治剂处理旺盛生长期的宽叶酢浆草,于施药后10、20、30 d调查株防效并且于药后30 d调查鲜质量防效。结果表明,40 g/L烟嘧磺隆油悬浮剂、41%草甘膦异丙胺盐水剂、200 g/L氯氟吡氧乙酸乳油、30%苯唑草酮悬乳剂、30%莠去津悬乳剂、15%硝磺草酮悬乳剂和25%砜嘧磺隆水分散粒剂施药后30 d对宽叶酢浆草的株防效和鲜质量防效均超过75%,其中41%草甘膦异丙胺盐水剂和15%硝磺草酮悬乳剂的株防效和鲜质量防效均超过99%,说明玉米地宽叶酢浆草可以用除草剂进行防治。

摘  要:
Oxalis latifolia is an important quarantine weed recently invading cultivated land and gardens of Yunnan Province. Seven herbicides were screened for controlling actively-growing O. latifolia in a corn field. Efficacy was determined at 10,20,and 30 days after treatment and fresh weight determined at 30 DAT. Efficacy and fresh weight reduction by nicosulfuron 40 g/L OF,glyphosate isopropylamine 41% AS,fluroxypyr 200 g/L EC,topramezone 30%SE,atrazine 30% SE,mesotrione 15% EC,rimsulfuron 25% WG were above 75%. Meanwhile,efficacy and fresh weight reduction by glyphosate isopropylamine 41% AS and mesotrione 15% EC were above 99 percent. It is clear that O. latifalia can be controlled by herbicides in corn fields.
