摘要

摘要在这项工作中，我们旨在制定一种生态友好的策略来管理R.solani抑制摩洛哥菌株的发病率。在评估了不同作物的阻尼发生率后，进行了温室实验，以评估化学和生物制剂对植物生长和阻尼控制的效率。结果表明，龙葵MN191236菌株的毒力最强，其严重程度指数显著增加，根长和荚数分别减少23%和58%。在受到龙葵感染的豆苗上，木霉使荚数增加了169%，严重程度指数降低了1.33。然而，甲基Tolclofos和低毒力尖孢镰刀菌菌株排在第二位。化学或生物制剂的效率与“致病菌株*杀菌剂或生物制剂”的相互作用显著相关。这些结果对龙葵的综合环保管理具有一定的前景。

Pathogenicity study of Rhizoctonia solani and its integrated management on different crop species in Morocco

Abstract In this work, we aimed to develop an ecofriendly strategy to manage the R. solani damping-off incidence of Moroccan strains. After the assessment of damping-off incidence on different crops, a greenhouse experiments were carried out to assess the efficiency of chemical and biological agents on plant growth and damping-off control. Results revealed that R. solani MN191236 strain was the most virulent as it dramatically increased severity indexes and reduced root length and pods number by 23% and 58% respectively. On R. solani-infested bean seedlings, Trichoderma asperellum increased pods number by 169% and reduce the severity index up to 1.33. However, the Tolclofos-methyl and the hypovirulent F. oxysporum strain came in second place. The efficiency of chemical or biological agents was significantly related to the interaction ‘pathogenic strains*fungicide or biological agents’. These results are promising in term of integrally and eco-friendly management of R. solani damping-off.

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.
