摘　　要：选用12种农用抗菌素、化学杀菌剂及生防菌剂对枣黑腐病Dothiorella gregaria Sacc.进行防治对比试验.结果显示,3%中生菌素WP 800倍、4%农抗120的WC 400倍、4%双抗WC 400倍、70%甲基托布津WP 800倍与4%农抗120的WC 400倍交替使用防治效果最好,自7月中旬幼果期至9月中旬喷3～4次,与1:2:200波尔多液2次交替使用,间隔10～15 d,可使病果率由34.70%～60.52%降至2.32%～18.43%,防治效果为69.55%～93.93%;相当或优于喷化学杀菌剂70%甲基托布津和50%退菌特.苹果益微防治效果为57.19%～82.65%.The experiments against jujube fruit black rot mainly caused by the fungus Dothiorella gregaria Sacc. were conducted with several agricultural antibiotics, fungicides and a biological control agent in the field. The results showed that 3 % zhongshengmycin WP 800 times, 4 % agri-antibiotic 120 WC 400 times, 4 % BI-antic WC 400 times as well as an alternate application of 70 % thiophanatemethyl WP 800 times and 4 % agricultural antibiotic120 WC 400 times had the best effect. The rates of infected fruits were reduced from 34.70%-60.52% to 2.32%-18.43%, after the spraying of the obove pesticides 3 or 4 times and alternated them with 1 ： 2 ： 200 bordeaux mixture 2 times at intervals of 10-15 days from the juvenile fruit period,i, e. ,mid of July to mid of September. The control effect ranged from 69.55 % to 93.93 %, equal or superior to the application of fungicide 70 % thiophanatemethyl and 50% tuzet. The control effect of YIB（yield-increasing bacteria）ranged from 57.19% to 82.65 %.
