Description

1. Technical field

[0001] The invention discloses a treatment method for drug-resistant wheat head blight, which belongs to the new application of fungicide and the invention of application technology thereof. Use the active ingredients of existing fungicides to completely or partially replace benzimidazole fungicides to prevent and control wheat head blight, control and delay the resistance of head blight bacteria to benzimidazole fungicides, and prevent the prevalence of drug-resistant head blight. 2. Technical background

[0002] Scab is one of the most important diseases in wheat production. Fusarium graminearum (Fusarium graminearum) is its main pathogenic fungus, which spreads through seeds and diseased residues, and can cause bud rot, seedling rot and ear rot of barley, wheat and other cereal crops, especially ear rot causing the most production loss serious. In the middle occurrence and epidemic years, it can cause the yield loss of more than 30%-50% of large wheat...
