摘要
经鉴定,蜜桃黑斑病的病原菌为链格孢(Alternartaalternata(Fr.)Keissl),主要危害果实,病班最早在果实第2次膨大期(7月中下旬)出现,以后继续发展。随着病斑的发展,症状表现为乳突状、黄尖、红尖(红斑)、褐腐和黑斑。

The initial spots appear during the second swelling period of fruit (from second to the last ten days of July)and expand in succession. With development of spot,one after another,the symptoms present nipple, yellow nipple, red nipple,brown rot and black spot.
