缩果病是枣树的重要病害。近年来，在河北省衡水枣树栽植区发生较为普遍。病株率在９０％以上，重病树落果遍地，好果率仅４０％左右，使枣果产量和质量受到很大影响。从１９９４年开始，我们对多种杀菌剂进行了试验，从中筛选出特谱唑（烯唑醇）为防治枣缩果病的理想杀菌... Fruit shrinkage is an important disease jujube. In recent years, Hengshui jujube tree planting area in Hebei Province is more common. The rate of diseased plants is over 90%. The severely diseased trees fall everywhere and the good fruit rate is only about 40%, which greatly affects the yield and quality of jujube. Since 1994, we have conducted experiments on various bactericides, and we have screened out the ideal bactericide of terfenadine (diniconazole) for the prevention and cure of jujube shrinkage diseases.
