The invention provides an RNA bacteriostatic agent miRNA482a, which has an RNA sequence shown in SEQ ID NO. 1. The invention also provides a crop pathogen inhibitor, which at least contains miRNA482a. Specifically, the inhibitor can be a spray containing miRNA482a, and effective prevention and treatment of botrytis can be realized by spraying. The solution applied with miRNA482a provided by the invention can significantly inhibit the germination of botrytis spores and the infection toxicity of botrytis to plants, and can be used for prevention and treatment of botrytis of vegetable crops. 本发明提供一种RNA抑菌剂miRNA482a，其具有SEQ ID NO.1所示的RNA序列。本发明还提供一种作物病菌抑制剂，所述抑制剂中至少包含miRNA482a。具体的，所述抑制剂可以为包含所述miRNA482a的喷雾剂，通过喷雾来实现对灰霉病的有效预防和治疗。本发明施加miRNA482a的溶液能显著抑制灰霉菌孢子的萌发以及灰霉菌对植物的感染毒力，可用于蔬菜作物的灰霉病的防治。
