壳寡糖衍生物对烟草花叶病的田间防效试验

摘要

测定了壳寡糖、宁南霉素、水杨醛壳寡糖希夫碱、5-溴水杨醛壳寡糖希夫碱、水杨醛壳寡糖希夫碱膦酸酯、5-溴水杨醛壳寡糖希夫碱膦酸酯对烟草花叶病的抑制效果，结果表明：这些药剂对烟草花叶病毒（ TMV）均具有一定的诱导抗病效应，其中以5-溴壳寡糖希夫碱膦酸酯药剂的防治效果较好。%The author tested the inhibitions of Chitosan oligosaccharide , Ningnan mycin, Salicylaldehyde chitosan oligosaccha-ride Schiff base , 5-Bromosalicylaldehyde chitosan oligosaccharide Schiff base , Salicylaldehyde chitosan oligosaccharide Schiff base phosphonate , 5-Bromosalicylaldehyde chitosan oligosaccharide Schiff base phosphonate to tobacco mosaic virus ( TMV) disease in field.The results indicated that all these drugs had certain effects of inducing resistance to TMV .Of all, 5-Bromosalicylaldehyde chitosan oligosaccharide Schiff base phosphonate had the best control effect against this disease .
