ABSTRACT The nematicidal effect of Purpureocillium lilacinum strain 251 and a formulated product containing chitosan was recorded against second stage juveniles (J2s) and eggs of Meloidogyne javanica. There was a significant gradual decrease in the number of J2s survival as the chitosan concentration increased. The survival of J2s and hatching of eggs of Meloidogyne javanica were influenced by the presence of chitosan at different concentrations. However increase of P. lilacinum concentration from 1 × 106 to 3 × 106 conidia g−1 soil did not significantly reduce J2s survival in the treated soil. There was a clear interaction effect between P. lilacinum and chitosan 14 days after inoculation of soil with J2s. This was not obvious when the incubation time was prolonged to 21 days. When the soil was inoculated with eggs, there was an interaction effect only in one experiment 14 days after inoculation. Higher level of infection of root-knot nematodes by P. lilacinum was evident after applying glucose in either sterilised or non-sterilised soil.

Purpureocillium lilacinum联合壳聚糖防治爪哇根结线虫的功效

摘要 记录了紫红色紫苏菌 251 株和一种含有壳聚糖的制剂对第二阶段幼虫 (J2s) 和爪形根结线虫卵的杀线虫作用。随着壳聚糖浓度的增加，J2s 存活的数量显着逐渐减少。J2s的存活和爪形根结线虫卵的孵化受不同浓度壳聚糖存在的影响。然而，将 P. lilacinum 浓度从 1 × 106 增加到 3 × 106 分生孢子 g−1 土壤并没有显着降低处理土壤中 J2s 的存活率。用J2s接种土壤14天后，紫丁香与壳聚糖之间存在明显的互作效应。当孵育时间延长至 21 天时，这一点并不明显。当土壤接种鸡蛋时，仅在接种后 14 天的一项实验中出现交互作用。在已消毒或未消毒的土壤中施用葡萄糖后，紫丁香对根结线虫的更高水平感染是明显的。
