Abstract

Abstract Impacts of AM fungus Rhizophagus irregularis and silicon dioxide nanoparticles (SiO2NPs) were observed on the disease complex of carrot (Daucus carota) caused by Meloidogyne incognita, Alternaria dauci and Rhizoctonia solani. Use of R. irregularis alone together with SiO2NPs (0.10 mg ml−1) caused a significant increase in plant growth and photosynthetic pigments and reduce disease indices, galling and population of M. incognita. Use of R. irregularis resulted in a lesser plant growth and photosynthetic pigments than foliar spay of NPs. Use of R. irregularis with NPs spray was best for the management of disease complex. Leaf blight and root rot indices were 3 when fungal pathogen was inoculated alone and indices were 5 when pathogens were inoculated together. Use of R. irregularis/NPs with A. dauci/R. solani reduced indices to 2, indices were reduced to 1 when R. irregularis was used with SiO2 NPs. Root colonisation by R. irregularis was higher when alone but reduced in plants sprayed with NPs. Inoculation of test pathogens reduced colonisation by R. irregularis. Various studied attributes showed a significant correlation in principal components analysis. Significant management of disease complex may be achieved by the use of R. irregularis with SiO2 NPs.

利用AM真菌不规则食根菌和二氧化硅纳米颗粒治理无名甜根线虫、稻瘟菌和茄枯丝核菌及胡萝卜生长

摘要研究了AM真菌“不规则食根菌”(Rhizophagus irregularis)和二氧化硅纳米颗粒(SiO2NPs)对胡萝卜(dauci)病复合体的影响，这些病复合体由不认识的甜根线虫(Meloidogyne incognita)、daucalternaria dauci和solani Rhizoctonia引起。与SiO2NPs (0.10 mg ml−1)联合使用，可显著提高野田鼠的植株生长和光合色素含量，降低野田鼠的疾病指数、刺痛和种群数量。喷施不规则叶面草对植物生长和光合色素的影响小于喷施植物叶面草。使用不规则白蚁与NPs喷雾剂对疾病复合体的管理效果最好。单独接种病原菌时，叶枯病和根腐病指标为3，共同接种时，叶枯病和根腐病指标为5。r.r irregularis/NPs与a.d uci/R。与SiO2 NPs混合使用时，茄泥的指数降至2，不规则草的指数降至1。喷施NPs后，不规则栗的根定殖率降低，而单独施时则升高。接种试验病原体可减少不规则弧菌的定植。主成分分析显示，各研究属性具有显著的相关性。使用带有SiO2 NPs的不规则棘球蚴可实现对复杂疾病的显著管理。

期刊介绍： Archives of Phytopathology and Plant Protection publishes original papers and reviews covering all scientific aspects of modern plant protection. Subjects include phytopathological virology, bacteriology, mycology, herbal studies and applied nematology and entomology as well as strategies and tactics of protecting crop plants and stocks of crop products against diseases. The journal provides a permanent forum for discussion of questions relating to the influence of plant protection measures on soil, water and air quality and on the fauna and flora, as well as to their interdependence in ecosystems of cultivated and neighbouring areas.
