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 effectson'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.
