Antifungal activities were tested against 7 pathogenic fungi by using agar disc diffusion and tube dilution tests. The results show that the commercial rice wine extracts of Allium fistulosum have strong antifungal activity against Aspergillus brasiliensis ATCC 16404, Candida albicans ATCC 10231, Microsporumcanis ATCC 36299, M. gypseum ATCC 24102, Trichophyton mentagrophytes ATCC 9533, T. rubrum ATCC 28188, and T. tonsurans ATCC 28942. The commercial rice wine extracts of different A. fistulosum parts were found to exhibit significant antifungal activities with the minimal inhibitory concentration (MIC) in the range of 0.2 - 1.0 mg/mL. The antifungal activity of the extracts of different A. fistulosum parts was in the order of AFS (stem) > AFI (plant body) > AFL (leaf) > AFR (root).展开更多
通过田间试验,研究二甲戊灵等7种除草剂及混剂对大葱田不同时期杂草的防除效果及对大葱的安全性,以期为大葱田筛选高效、安全的禾本科杂草及阔叶杂草除草剂。结果表明,大葱移栽期、杂草苗前进行土壤封闭处理,二甲戊灵单剂对禾本科杂草...通过田间试验,研究二甲戊灵等7种除草剂及混剂对大葱田不同时期杂草的防除效果及对大葱的安全性,以期为大葱田筛选高效、安全的禾本科杂草及阔叶杂草除草剂。结果表明,大葱移栽期、杂草苗前进行土壤封闭处理,二甲戊灵单剂对禾本科杂草有较好防效,最高达到100%,但对阔叶杂草防效差;乙草胺单剂和精异丙甲草胺单剂对总草的防效均较低,介于36.39%~40.75%;二甲戊灵与乙氧氟草醚、辛酰溴苯腈混配均可以有效地防除杂草,其中二甲戊灵与乙氧氟草醚低剂量混配效果最佳,对总草的防效为68.28%,大葱的生长促进率为9.59%、增产率为11.81%。大葱生长期、杂草3~5叶期喷雾,精喹禾灵和乙氧氟草醚低剂量混配、精喹禾灵+辛酰溴苯腈+乙氧氟草醚三元复配对禾本科杂草和阔叶杂草防除效果最好,对总草的防效分别为74.74%、76.52%,前期虽对大葱有轻微药害,但不影响后期产量,大葱的生长促进率分别为1.29%、7.92%,大葱的增产率分别为88.96%、70.42%;精喹禾灵单剂、精喹禾灵和辛酰溴苯腈混配防除阔叶杂草效果较差,精喹禾灵和灭草松混配对除马泡瓜外的禾本科杂草和阔叶杂草都有一定的防效,这几种处理对总草的防效均低于40%。杂草苗前,推荐使用330 g/L二甲戊灵EC 2 250 m L/hm2+24%乙氧氟草醚EC 300 m L/hm2混配;杂草3~5叶期,推荐使用10%精喹禾灵EC 675 m L/hm2+24%乙氧氟草醚EC 900 m L/hm2、10%精喹禾灵EC 675 m L/hm2+30%辛酰溴苯腈EC 1 200 m L/hm2+24%乙氧氟草醚EC 750 m L/hm2混配,可以安全、有效地防除大葱田禾本科杂草及阔叶杂草。展开更多
