Most summer residents are well aware that the process of growing garlic on a personal plot is quite laborious. It is very important to provide the plant with solar heat, prepare the soil, and meet the planting dates. Otherwise, garlic diseases will very soon make themselves felt, and the harvest may be low. So, what ailments can kill garlic?
They primarily include the stem nematode. This is a small worm that lays hundreds of eggs in the tissues of garlic. The microorganism infects the plant to such an extent that the bulb simply crumbles into cloves, and the leaves become sick. To minimize such diseases of garlic, the seedlings are pre-treated with a special saline solution, and then soaked in water, cooled and dried.
Insects also cause damage to the plant, among which the onion fly is a particular threat. She places her future offspring under the lumps of earth near the garlic or on the bottom of the bulb. After ten days, larvae appear from the eggs, which enter the bulb through the base of the leaves or the bottom. Similargarlic diseases are necessarily accompanied by yellowing and drying of the leaves. After twenty-one days, the larvae move into the ground and wait to pupate. In early August, flies fly out again, which will also lay eggs.
To reduce the risk of onion fly damage, the soil is dug up and early shoots are treated with ash or tobacco ash.
Considering the main diseases of garlic, one cannot fail to mention downy mildew. Its first sign is the formation of blurry spots of a pale green hue on the leaves, which subsequently turn gray. Infected leaves eventually turn yellow and die. From them, the disease moves to the bulb, the garlic is sick with downy mildew all winter, and when spring comes, it again affects the leaves, as well as the arrows. The disease progresses strongly in sunny and humid weather.
In order to control downy mildew, the seedlings are heated before being placed in the ground, and after twenty-one days, the seedlings are treated with a solution of copper oxychloride.
It should also be noted that the stem nematode and downy mildew are diseases of winter garlic.
Garlic is also prone to black mold disease. Its cause is a fungus that appears in storage conditions at high air temperatures. The microorganism infects the head of garlic, which forms a dark coating. In the event that the disease progresses, the garlic dries out completely. Especiallypoorly dried and immature plants are susceptible.
To eliminate the possibility of black mold, it is necessary to ensure the plant is properly stored and dried properly. If the disease has damaged the heads, additional drying should be done, and the plant should be treated with crushed chalk.
Thus, pests and diseases of garlic can seriously affect the quality of the crop. To prevent this, it is necessary to provide the plant with appropriate care.
