[目的]为新疆鹰嘴豆褐斑病的防治提供理论依据。[方法]采用菌丝生长速率法测定了9种杀菌剂对鹰嘴豆新病害褐斑病病菌Ascochyta rabiei Pass.的毒力。[结果]10%苯醚甲环唑WG、25 g/L咯菌腈FS、30 g/L苯醚甲环唑FS、50%嘧菌环胺WG四种药剂抑菌作用最强,药后10 d,EC50值为0.001-1.461 mg/L范围内,持效期可达20 d以上。其次是30%苯甲.丙环唑EC、50%多菌灵DF,药后10 d,EC50值在1.544-3.280 mg/L范围内,也表现较好的抑菌作用。[结论]10%苯醚甲环唑WG、30%苯甲.丙环唑EC、25 g/L咯菌腈FS、50%嘧菌环胺WG和30 g/L苯醚甲环唑FS抑菌效果好,可以适当轮用。
[Objective] The research aimed to provide theoretical basis for prevention and treatment of chickpea brown spot in Xinjiang. [Method] The mycelial growth rate method was used to determine the toxicity of 9 fungicides to Ascochyta rabiei Pass. [Result] The four antibacterial agents of 10% difenoconazole WG, 25 g / L fludioxonil FS, 30 g / L difenoconazole FS and 50% 10 d, the EC50 value ranged from 0.001 to 1.461 mg / L, and the persistence period could reach more than 20 d. Followed by 30% Benzocycloconazole EC and 50% Carbendazim DF. EC50 value was in the range of 1.544-3.280 mg / L at 10 days after drug treatment, and also showed good antibacterial activity. [Conclusion] 10% difenoconazole WG, 30% benzofenoxazole EC, 25 g / L fludioxonil FS, 50% cyprodinil WG and 30 g / L difenoconazole FS Bacteria effect is good, you can use appropriate rotation.
