【摘要】 初步试验表明 ,硫酰氟 2 5～ 5 0 g/ m2 对土壤真菌 (Fusarium sp.)、线虫均有良好的杀灭效果 ,防治后番茄产量与使用溴甲烷 5 0 g/ m2相当。硫酰氟蒸汽压高 ,穿透性强 ,可杀死深土层中的线虫及病原菌。由于其在常温下是气体 ,即使在冬天使用 ,也不需要搭小拱棚或采用“热法”施药 ,因此比使用溴甲烷更为方便 ;使用时也不像威百亩那样需要专用的施药设备。因此 ,硫酰氟是溴甲烷土壤消毒很有前景的替代品更多还原

【Abstract】 The results of preliminary experiments show that sulfuryl fluoride, 25～50 g/m 2, presented good control efficacy to both soil born fungal pathogens and nematodes. The yield of tomato after applying sulfuryl fluoride was similar to that obtained from methyl bromide treated plots. The application of sulfuryl fluoride is more convenient than that of methyl bromide because the tension of sulfuryl fluoride is higher and sulfuryl fluoride is gas under normal temperature. The application does not need to make small arches or use hot system. Besides, it does not need specific equipment applied for metam sodium. So, sulfuryl fluoride is a promising alternative to methyl bromide in soil fumigation.更多还原
