| 摘 要： | 为了筛选用于禾草病害防治的高效、低毒、低残留的杀菌剂,本试验选用6种常见的杀菌剂对3种禾草病原菌进行了室内毒力测定及田间试验。结果表明,苯菌灵对褐斑病菌和炭疽病菌的EC50值分别是0.492 4,0.446 6 mg/L,多菌灵对禾草云斑病菌的EC50值是0.413 0 mg/L,其抑制作用最好。田间药效试验表明,50%苯菌灵WP(750 g/hm2)防治禾草褐斑病和禾草炭疽病、25%多菌灵WP(750 g/hm2)防治禾草云斑病有各自较好的防治效果,在药后10 d的防效分别是75.40%,72.06%和76.97%。室内毒力测定与田间药效试验结果表现一致,且6种供试药剂防治3种禾草病害具有明显的时效性。

| Abstract: | Virulence determination on three pathogens of grass diseases and field trials with six fungicides were carried out. The EC50 of benomyl to Rhizoctonia solani and Colletotrichum gloeosporioides were 0.492 4 and 0.446 6 mg/L, respectively. The EC50 of carbendazim to Rhynchosporium secalis was 0.413 0 mg/L. Carbendazim had the highest toxicity of the fungicides to Rhynchosporium secalis. The field control efficacy of 50% benomyl against Rhizoctonia solani and Colletotrichum gloeosporioides of turfgrass was 75.40% and 72.06%, respectively, while the control efficacy of 25% carbendazim on Rhynchosporium secalis was 76.97%. |
