Garlic pessimism is a relatively serious disease in the garlic cultivation process, with a reduction of more than 30 per cent in production and possibly even a loss of harvest. So what are the symptoms, symptoms and techniques for the integrated treatment of garlic albinos? Let's take a look
I. Symptoms of morbidity
The disease is mainly harmful to leaves, herbs and rods. When the disease begins, it turns yellow from the tip of the outer leaf to the lower strip, and then spreads to the heart leaf and the sheath, the plant grows weak, the whole plant is yellowden or dead, and it looks like a physical disease. A strain is removed, with water stains on the skin of the rods and a grey filament. In the later stages of the fungus filament, a sesame pelvis-sized brown-bacterium nuclei are produced, the spas are blackened and decomposed, and in the fields they tend to be the first to emerge。
Ii. Characteristics of morbidity
1. The fungus nuclei of the disease through which it is transmitted survives in the soil and is transmitted by rainwater or irrigation water, which enters directly from the roots or the ground, causing the growth of the strain and the emergence of the infection. The fungus fusion into brown and black micronuclei spreads over the stands. The fungus is cold, hot and humid, at temperatures below 20°c, and is more prone to outbreaks of humidity above 90%. As a result, multiple rainy seasons are characterized by rapid outbreaks of disease, which can be exacerbated, in particular by weak growth and a combination of diseases. High temperatures and low humidity adversely affect the disease. It started in february, flourished in march and became more serious in april。
2. Different types of diseases are investigated, with the incidence of white garlic being higher than that of purple garlic, while the incidence of white garlic is between 20 and 30 per cent, compared with 8 and 15 per cent. In addition, early spring is prone to disease in the garlic field, which is growing thin and has a low face, with rapid spread after entering the rainy season。
Iii. Integrated response technologies
1. As the rotation of garlic paste as a home-borne disease is an important route to disease, it is not appropriate to reconnect it with non- garlic crops for a period of more than three to four years, and water and drought are better used to reduce the primary source of infection。
2. Garlic treatment can effectively cut off the path to primary abuse and prevent disease. Garlic can be treated with 50% more fungus before sowing, by using 500 g more than 500 g more than 500 g more per 50 kg garlic for 3-5 kg of water ( evenly spilled on garlic), drying and then planting。
3. Plantation according to different harvest targets, such as the harvesting of garlic should be based on white garlic, with a percentage of violet garlic, which should be harvested before the outbreak of the disease and avoid its harmful effects; while those who harvest garlic and garlic should be equipped with the more resistant garlic。
4. Strengthening of pedestals for the pursuit of fertilizing seedlings, pine soil, drainage and precipitation in the early spring, promoting the growth and resilience of garlic in combination with high-yield, high-quality cultivation techniques of garlic; detecting the timely removal of strains, bringing them out of the field to dry and to burn them together, and strictly prohibiting on-site application and fertilization in order to prevent further introduction of bacteria into the field. The garlic harvest was followed by the clean-up of the sick and the covered, centralized burning, deep-turning of the land, dry-water rotations and rational planting。
5. At the beginning of the treatment, 50 per cent of the pharmacists can be treated with 500 times more liquid or 50 per cent more liquid sprayed with methyl sulphagus, one time between 7 and 10 days and two to three consecutive times; at the same time, 50 per cent can be treated with 1,000 to 1,500 times more liquid rinsing roots, one time every 7 to 10 days and two times more continuously. The rooting method works better than the spray control method, and the drug was stopped one week before the harvest。
