摘  要：
枇杷拟盘多毛孢菌生长温度范围为10～30℃,最适温度为20～25℃。在碳源中,以对蔗糖、乳糖和葡萄糖利用为佳,其中蔗糖和葡萄糖最适合病菌产孢;在氮源中,以对蛋白胨、磷酸铵、硝酸铵和硝酸钾利用为佳,其中硝酸钾最适合病菌产孢,而硫酸铵不利病菌生长,尿素可抑制病菌生长。室内试验结果表明,1～100mg·L-1浓度的50%施保功WP、50%多菌灵WP、68%多菌灵·代森锰锌WP和50%多菌灵·施保功WP均能有效抑制该病菌菌丝生长和产孢。田间试验结果也表明,50%多菌灵·施保功WP1.00kg·hm-2防治枇杷叶斑病效果最好,防效为93.27%;68%多菌灵·代森锰锌WP2.50kg·hm-2次之,防效为80.34%。

摘  要：
The temperature range for Pestalotiopsis eriobotryfolia growth was 10-30℃, the optimum temperature was 20-25℃.The pathogen grew well on the media using sucrose, lactose and glucose as carbon sources and using peptone, ammonium phosphate, ammonium nitrate and potassium nitrate as nitrogen sources;sucrose and glucose as carbon sources and potassium nitrate as nitrogen sources were suitable for the sporulation of the pathogen However,ammonium sulfate as nitrogen source was not beneficial for the growth of the pathogen, urea as nitrogen source could inhibite the growth of the pathogen completely.50% Sporgon WP, 50% carbendazim WP, 68% carbendazim·mancozeb WP and 50% carbendazim·sporgon WP (100 mg·L-1,10 mg·L-1 and 10 mg·L-1) could inhibite effectually the growth and sporulation of pathogen.In the field, the results showed that control efficiencies of 50% carbendazim·sporgon WP 100 kg·hm-2 was the best,up to 9327%; the next one was 68% carbendazim·mancozeb WP 250 kg·hm-2,and its control efficiencies was 8034%.
