Garlic is one of the traditional agricultural crops in China and is called a "natural antibiotic." It is not only widely eaten, but also has good medicinal value. However, as people's demand for garlic continues to increase, garlic virus diseases are becoming more and more serious. This article will start with the symptoms and prevention and control measures of viral diseases to provide reference for the healthy development of the garlic industry.
The cause of virus disease Garlic virus disease is a plant disease caused by a variety of viruses. Common ones are bulb Huanglong virus, digging hole virus, garlic mosaic virus, etc. These viruses are usually spread through infected seeds, soil or insects.
Symptoms 1. Bulb Huanglong virus infection: The leaves show yellow-green, red-brown, and white spots, the bulb outer skin shows irregular depressions, and the internal texture is soft, black, and smelly.
2. Dig hole bacterial virus infection: The bulb appears as multi-strip, asymmetric depressions, forming obvious pits. At the same time, leaves will appear chlorosis, yellowing and other symptoms.
3. Garlic mosaic virus infection: The leaves appear yellowed and albinized, showing the shape of plum blossoms. Although bulbs will not show serious symptoms, their quality will also be affected.
Prevention and control of viral diseases 1. Planting disease-resistant varieties: During the planting process of garlic, varieties with strong disease resistance should be selected, which can reduce the possibility of disease occurrence.
2. Strengthen field management: Keep the fields dry, drain and drain water in a timely manner, reduce soil moisture, and reduce the chance of garlic diseases.
3. Strengthen nutrition for garlic: During the growth process of garlic, apply fertilizer and topdressing in time to make it grow healthily and enhance its own immunity.
4. Timely pest control: During the planting process, remove pests in the field in time to prevent pests from spreading the virus.
5. Administration of drugs: After garlic is found to have symptoms of viral disease, drugs can be used for treatment. However, pay attention to the use and dosage of the drug.
6. Strengthen prevention and control measures: During the growth process of garlic, strengthen prevention and control awareness, identify problems in a timely manner, and take effective measures to deal with them to avoid the spread of diseases.
7. Reasonable rotation: During the planting process of garlic, attention should be paid to reasonable rotation and not continuous planting to avoid the decline of soil quality and the occurrence of diseases.
8. Regular inspection: During the planting process, the growth of garlic and the occurrence of virus diseases should be regularly checked, problems should be dealt with in a timely manner, and diseases should be prevented.
Garlic is one of the traditional agricultural crops in my country, but it is affected by viral diseases, which will have a serious impact on its yield and quality. During the garlic planting process, we must pay attention to field management, strengthen prevention and control measures, and take effective measures to prevent the occurrence of viral diseases. Only in this way can the healthy development of the garlic industry be protected.
