Abstract

The invention discloses a method for artificially inducing field wheat scab, belonging to plant disease technical field. The method includes culturing conidiophore of wheat scab strain; preparing wheat scab strain inoculum; preparing moisture-retaining cloth; inoculating wheat scab strain inoculum, and retaining moisture; observing disease condition, recording, and performing statistics. The method retains moisture with moisture-retaining cloth, to significantly improve environmental humidity of wheat ear position and balance temperature, thereby facilitating invasion and fixation of wheat scab strain and improving field wheat scab artificial inducement effect. The method has simple implementation, no need of high input of manual labor and high-cost facilities, and applicability to wheat planting test areas.

Description

technical field

[0001] The invention relates to the technical field of plant diseases, in particular to a simple, efficient and labor-saving method for inducing wheat head blight by artificial inoculation in the field. Background technique

[0002] Wheat head blight is one of the main diseases in the warm, humid and semi-humid wheat regions of the world, and it is also an important disease that affects the yield and quality of wheat in the middle and lower reaches of the Yangtze River and South my country wheat regions. It includes barley scab and wheat scab, the causative bacteria of these two diseases are Gibberella zeae (Schw.) Petch, and the yield loss caused by them is generally 10% to 20% in a year, The reissue year can reach 20% to 30%.

[0003] The occurrence of wheat head blight needs to meet the following two conditions: one is the source of pathogenic bacteria, and the other is suitable temperature and humidity conditions. If these two conditions are not met, it...
