由胶孢炭疽菌引起的核桃炭疽病是目前危害山东省核桃生产的主要病害。为筛选防治该病害的高效药剂,山东农业大学林学院科研人员在确定了最适菌丝生长和分生孢子萌发温度的基础上,采用菌丝生长速率法和孢子萌发法,测定了8种常用杀菌剂对胶孢炭疽菌的毒力,评估了温度对咪鲜胺和戊唑醇毒力的影响,检测了17个胶孢炭疽菌菌株对咪鲜胺和戊唑醇的敏感性,同时评价了这2种杀菌剂的预防和治疗作用。研究结果显示:在胶孢炭疽菌菌丝生长和孢子萌发的最适温度28℃下,供试8种杀菌剂中,咪鲜胺、戊唑醇和三唑酮对供试菌株菌丝生长的抑制作用最强,平均EC50值分别为
Walnut anthracnose caused by Colletotrichum gloeosporioides is the main disease which is harmful to the production of walnut in Shandong province. In order to screen the effective agent for controlling the disease, researchers at Shandong Agricultural University, College of Forestry, determined the optimal mycelial growth and conidial germination temperature on the basis of mycelial growth rate and spore germination method, the determination of eight commonly used Fungicides on Colletotrichum gloeosporioides toxicity, to assess the temperature of prochloraz and tebuconazole virulence, detection of 17 strains of Colletotrichum strains of prochloraz and tebuconazole sensitivity, while the evaluation The two kinds of fungicides for the prevention and treatment. The results showed that among the eight fungicides tested, the inhibitory effects of prochloraz, tebuconazole and triadimefon on the mycelial growth of tested strains were observed at the optimum temperature of mycelial growth and spore germination of Colletotrichum; The strongest effect, the average EC50 values were
