为了筛选出防治降香黄檀炭疽病的环境友好型药剂,本文测定了10种杀菌剂的室内毒力,并从中筛选出毒力较强的药剂进行林间防效试验。结果表明:25%丙环唑EC,60%唑醚·代森联WG和40%氟硅唑EC对降香黄檀炭疽病菌的毒力较强,其EC50分别为0.12,0.15和1.12mg/L。其他供试药剂的EC_(50)分别为:75%百菌清WP 231.42mg/L,10%苯醚甲环唑WG 3.60mg/L,80%醚菌酯WG 1.58mg/L,70%甲基硫菌灵WP 4.51mg/L,3%中生菌素WP 19.36mg/L,80%代森锰锌WP 79.76mg/L,80%多菌灵WP 11.47mg/L。考虑到氟硅唑、唑醚·代森联价格较高,建议将这两种药剂使用在降香黄檀苗木炭疽病的防治上。人工林炭疽病的防治采用25%丙环唑EC、 80%醚...

In order to screen pesticides against anthracnose of Dalbergia odorifera,the indoor toxicity and the field control efficacy of ten fungicides were investigated.25％ propiconazole EC,60％ pyraclostrobin · metiram WG and 40％ flusilazole EC showed the strong virulence against anthracnose of D.odorifera with EC50 values of 0.12,0.15 and 1.12 mg/L,respectively.The EC50 of 25％ chlorothalonil EC was 231.42 mg/L,10％ difenoconazole WG was 3.60 mg/L,80％ kresoxim-methyl WG was 1.58 mg/L,70％ thiophanate-methyl WP was 4.51 mg/L,3％ zhongshengmycin WP ...
