摘要
应用寡聚半乳糖醛酸对苹果花叶病进行了田间药效试验,结果表明:寡聚半乳糖醛酸水剂稀释300～500倍,对苹果花叶病防效达87.81%～92.08%.其防效比对照药剂20%病毒的防效81.11%高,比对照区增产20%～23%.是防治苹果花叶病较理想的药剂.
s: The field trial of Oligogalacturonides controlling apple mosaic was done ,the results indicated that the controlling efficacy of Oligogalacturonides diluted 300-500 times by water was 87.81%~92.08% which was higher than that 81.11% of contrast pesticide-Dukexing.The range of increased yield of the tree sprayed oligochitosan was 20%~23%. Oligogalacturonides is a good biocide to controlling Apple mosaic.
