Latest Tutorial on the Main Disease Prevention and Control Techniques for Garlic Sprouts

Garlic sprouts are a vegetable we are all familiar with. They are the seedlings of garlic that have grown to a certain stage, with the spicy flavor of garlic. They are nutritious and also help with digestion, and can prevent diseases such as influenza and enteritis. However, during cultivation they can be attacked by a variety of diseases, and if not controlled in time, this can cause huge losses. Below, let's take a look together with the editor at the prevention and control techniques for common diseases of garlic sprouts.

1. Purple blotch

It mainly harms the leaves. When the disease occurs, it always starts at the leaf tips and flower stalks, then spreads to the lower part in a short time, producing small white sunken spots that are slightly purple in the middle and gradually expand into yellow-brown oval lesions. When humidity is high, black moldy growth appears on the lesions; these are the conidia of the pathogen. The lesions mostly have concentric rings and break off very easily.

Prevention and control methods: In the early stage of the disease, fungicides such as chlorothalonil, iprodione, and oxadixyl can be sprayed for control, once every 7-10 days, for 3-4 consecutive sprays, with good control results.

2. Leaf blight

This disease is a fungal disease and mainly harms the leaves. In the early stage, it starts from the leaf tips and gradually develops toward the leaf base, and spreads from the lower part of the plant upward. When the disease occurs, white round spots appear and gradually expand into gray-brown, irregular oval lesions. In severe cases, the leaves of the whole plant wither and the plant dies. In the later stage, black moldy growth also appears on the diseased areas, scattered with small black granules.

Prevention and control methods: After the plant is infected, treat it promptly to prevent the disease from spreading. Carbendazim can be sprayed once every 7 days. Zineb or chlorothalonil can also be sprayed, also once every 7 days, for 2-3 consecutive sprays, with good results.

3. Soft rot

This is a bacterial disease, and it is very easily triggered in low-temperature and high-humidity environments. It first develops at the leaf margins or veins, forming yellow-white streaks along the leaf margins and veins that can run through the entire leaf. When humidity is high, the lesions become yellow-brown and soft-rotted, accompanied by a foul odor, and the leaves completely lose their photosynthetic function. It generally occurs on the basal leaves and spreads upward to the leaves, and in severe cases can cause the whole plant to turn yellow and die.

Prevention and control methods: This disease mainly occurs because pests bite and wound the leaves, allowing the pathogen to invade, or because pests carry the pathogen and directly spread the disease. Therefore, to control soft rot, pest control is very important. In the early stage, attention should be paid to controlling underground pests such as wireworms and mole crickets. At the seedling stage, attention should be paid to root maggots, flea beetles, and others. When the disease occurs, agricultural streptomycin or amobam can be sprayed once a week, for 2-3 consecutive sprays depending on the condition, with good results.
