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%。

Abstract: 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 100 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%.
