Corn smut is a systemic disease infested at the seedling stage, and typical symptoms usually appear in the ear stage. The prevention methods are as follows:
1. Select disease-resistant varieties and coat with a seed coating that prevents silk smut.
2. Reasonable rotation, performing more than three years of rotation is an effective way to reduce corn smut. Especially in places where corn smut is serious, it is necessary to use a variety of crops such as potatoes and beans to avoid repeated planting for many years. It is really unreasonable, and it is necessary to rotate and plant disease-resistant varieties.
3. Do a good job of dressing with pesticides. Before sowing, you should use “teconazole†and “malignant†to mix seeds and kill the seeds.
4. Suitable sowing, seed selection, seeding, and shallow sowing before sowing to speed up germination and emergence, and reduce the chance of pathogen invasion.
5. Application of composted manure, manure or compost containing sick bodies, must be fully decomposed before application, preferably not in corn, to prevent pathogens from being introduced into the field with manure.
6. Dispose of the diseased plants in time, remove the diseased plants in the field in time, and bring out the field management, and do not discard them at will. Incinerate the corn residue in the previous year to eliminate the source of sterilization and reduce the incidence.
Nowadays, due to the constant changes in natural conditions such as temperature and precipitation, many diseases often occur during the growth of crops. Therefore, pesticide fungicides can be used in advance to prevent them. In the later stage, pesticide products must be timely controlled if they occur.
