摘要
生物防治是芒果胶孢炭疽病防控的主要措施之一。为了系统性评价生防菌的防控效果,为生防菌剂的生产应用提供指导,本文采用离体叶片针刺法,室内评价了18种生防菌对‘贵妃’‘台农1号’两个芒果主栽品种叶部炭疽病的防护、治疗和兼防兼治效果。结果表明,生防菌对两个主栽品种的芒果叶部病害的防效具有一致性,18种生防菌均具有防护、治疗和兼防兼治的作用,其中对‘贵妃’芒果效果较好的是S8(蜡质芽孢杆菌菌剂)、S3(枯草芽孢杆菌菌剂),对‘台农1号’芒果效果最好的是S3;田间防治芒果叶部炭疽病试验表明,S8、S9(枯草·纳豆·地衣芽孢杆菌·硝化细菌)效果较好,防效超过90%,可以应用于芒果叶部胶孢炭疽病的生物防治中。
Biological control is one of the main measures for the prevention and control of mango anthracnose.In order to systematic evaluation of control effect of bio-control bacteria,provide guidance for the production and application of bio-control agents,this article evaluated protective,therapeutic,combined prevention and treatment effects of 18 biocontrol bacteria on the leaf anthracnose of two main varieties of mango,‘Guifei’mango and‘Tainong No.1’mango,indoors.The results showed that the control effect of bio-control bacteria on the leaf diseases of two main varieties of mango was consistent.All 18 bio-control bacteria had protective,therapeutic,and combined prevention and treatment effects.Among them,S8(Bacillus cereus)and S3(Bacillus subtilis)had better effects on‘Guifei’,and S3 had the best effect on‘Tainong 1’mango.The field experiment on preventing and controlling anthracnose in mango leaves showed that S8 and S9(Bacillus subtilis·natto·licheniformis·nitrifying bacteria)had good control effects,with a control efficiency of over 90%,and could be applied in the biological control of Colletotrichum gloeosporioides in mangoes.
