Abstract: Ring rot of apple fruit is one of the important apple diseases in Henan province. Experiments on the biological control of ring rot of apple fruit were carried out in laboratory and field in Zhengzhou from 1990 to 1992. The results showed that antibiotics 751 and B 903 have bacteriostatic action for Physalospora piricola. The bacteriostatic diameters were 11.77mm - 18.70mm. The rate of rot apple fruits and the number of spot in leaves treated with antibiotic 751 (100 time of ferment solution) and Bordeaux mixture alternately were lower than that treated with chemicals. The treatment of apple fruits with QGF (a compound of antibiotic 751) before storage resulted in controling diseases of the fruits and keeping them fresh more effectively.

Key words: Ring rot of apple, Biological control, Antibiotic
