"Skin disease" is a kind of root rot disease of wind protection, and it is one of the serious soil-borne diseases that are often caused by the replantation of root crops. Infected with wind disease, tiger's skin disease, the root will appear horizontally and vertically diamond-shaped tan dots. With the corkation of yellow-brown lesions, the epidermis of the rhizome becomes abnormally rough, and the center is slightly scabbed and hardened in the middle. Lesions are limited to the skin and do not penetrate into the phloem. The "skin disease" bacteria rot in the soil or overwinter on seedlings. The bacteria in the soil are infective after invading from the lenticels or wounds, and it is difficult to invade the surface of the tubers after they have been tethered. Plants that grow out of disease are prone to disease, and the incidence of severe crops is more serious. Temperatures of 25°C to 30°C, neutral or slightly alkaline sandy loam, and soils below pH 5.2, rarely occur. Causes of morbidity: Firstly, long-term and excessive use of chemical fertilizers is unreasonable, resulting in soil compaction, acidification, salinization, and serious imbalance of nutrients, thereby reducing the disease resistance of crops. The second is the long-term application of organic manure without decomposition, such as chicken manure or manure, which contains large amounts of antibiotics and salt, which will destroy the structure of the soil aggregates, aggravate the soil compaction, cause serious imbalance of water, fertilizer, gas and heat, and make the soil The pests and diseases in the more and more difficult to cure. Third, the beneficial bacteria in the soil are destroyed, trace elements cannot be absorbed and utilized, and the lack of boron and calcium deficiency in the soil is the culprit in the windbreak “tiger diseaseâ€. Control methods: 1. Increase the use of beneficial bacteria and trace elements, reduce the use of compound fertilizer, so that balanced fertilization. 2. Combine and control the underground pests in early July. One kilogram of mancozebite or 1 kg or 1-2 kilograms of soil conditioner can be used per acre with water. 3. In June and August, use 25 grams of Dasheng (Manson Manganese) + 15 grams of Boron Boron + 15 grams of Fruit and Vegetable Calcium or 30 grams of Fluorinated Triethylphosphonate, for a bucket of water (15 kilograms) ) Spraying is performed 2-3 times in succession, preferably at intervals of 7-10 days.
