摘要

摘要 2016年8月至2017年10月，在实验室和盆栽试验中对14种不同的杀菌剂抗三叶金花菌进行了研究评价。体外评价结果表明，Amiscore 32.5 SC、Bavistin DF、Cabrio Top、Xtracare 300 EC、Nativo 75 WG、Provax 200 WP和Trooper 75 WP可100%减少径向菌丝生长。在盆栽试验中，Nativo 75 WG（0.2%）比对照病害发生率降低最高（85.38%），而 Provax 200 WP（0.3%）在降低病害发生率方面的效果为 82.14%。Nativo 75 WG 的病害严重程度最低（3.70%），Provax 200 WP 的病害严重程度也为 4.40%。Nativo 75 WG 的健康谷粒数最多（16.40 粒/穗），Provax 200 WP 的健康谷粒数（15.00 粒/穗）接近 Nativo 75 WG。在每穗粒重方面，Nativo 75 WG（0.2%）比对照组显著增加了 160.47%。

Efficacy of different fungicides on wheat blast disease caused by M. oryzae pv. triticum in vitro and vivo condition

Abstract The experiment was studied to evaluate the fourteen different fungicides against M. oryzae pv. triticum in laboratory and pot experiment from August 2016 to October 2017. The result of the in-vitro evaluation showed that a 100% reduction of radial mycelial growth was obtained in Amiscore 32.5 SC, Bavistin DF, Cabrio Top, Xtracare 300 EC, Nativo 75 WG, Provax 200 WP and Trooper 75 WP. Nativo 75 WG (0.2%) revealed the highest (85.38%) reduction of disease incidence over control while Provax 200 WP (0.3%) showed an efficacy of 82.14% in reducing disease incidence in the pot experiment. The lowest (3.70%) disease severity was found in Nativo 75 WG, and Provax 200 WP also exhibited 4.40% disease severity. A maximum number of healthy grain/ear (16.40) was observed in Nativo 75 WG, and Provax 200 WP was demonstrated with healthy grain (15.00), which was close to Nativo 75 WG. In grain weight/ear, Nativo 75 WG (0.2%) led to an impressive increase of 160.47% over control.

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.
