RNA bacteriostatic agent miRNA482a and crop pathogen inhibitor

Abstract

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.

Description

technical field [0001] The invention relates to the protection and treatment of botrytis cinerea, in particular to RNA bacteriostatic agent miRNA482a and a crop fungus inhibitor. Background technique [0002] Botrytis cinerea is a plant fungal disease caused by Botrytis cinerea. It can infect more than 200 kinds of fruits and vegetables such as tomatoes, strawberries, peppers, grapes, beans, and leeks. The host range is extremely wide. Botrytis cinerea is mainly transmitted by airflow, and the transmission speed is very fast, which makes the prevention and control of the disease very difficult in the process of tomato facility agriculture. With the continuous expansion of the planting area of ​​protected cultivation agriculture, gray mold of tomatoes cultivated in protective facilities such as plastic greenhouses, greenhouses, and small arch sheds also commonly occurs. In general, the annual output reduction reaches 20% to 30%, and in severe cases it reaches more than 50%. ...
