9种杀菌剂对小麦纹枯病菌的毒力及田间药效
Toxicity and Field Efficacy of 9 Fungicides Against Rhizoctonia cerealis
摘要
Abstract
The laboratory toxicity of nine fungicides against Rhizoctonia cerealis was tested by mycelium growth rate method,and the field efficacy trial was also carried out.The results indicated that 10％ hexaconazole SC,43％ tebuconazole SC and 12.5％ diniconazole WP showed the best inhibitory activity against the growth of R.cerealis with the EC50 value of 0.0651 ～0.6315 mg/L.The 10％ polyoxin WP,30％ ethylicin AS,250 g/L propiconazole EC,50％ carbendazim WP and 20％ triadimefon EC had better antibacterial activity with the EC50 value of 1.3006 ～4.2026 mg/L.The 43％ tebuconazole SC (500 mg/L),12.5％ diniconazole WP (500 mg/L),10％ hexaconazole SC (500 mg/L) and 250 g/L propiconazole EC (500 mg/L) showed better field control effects with the value of 68.7％,66.0％,65.3％,63.3％,respectively.关键词
