Fruit tree rot is a disease that is difficult to treat. In the past, more pesticides such as Formamide, such as Formamide, were used to prevent and control harmful pesticides. This does not meet current non-pollution production requirements. Some of the non-pollution prevention methods with simple operation and obvious effects that are used in the prevention and control work in recent years are described below for reference. 1, mud prevention and control method: Take fresh soil and mix well with water, the degree of wetness can be squeezed into a mud group can stick to the bark. Smear on fruit trees, thickness 3-5 cm, around the sickness 5 cm, and then tightly wrapped with a plastic film to prevent evaporation and mud loss. After 1 year, the plastic film and mud were removed. In this way, aerobic bacteria can suffocate due to chronic hypoxia. The cure rate of this method is above 90%. 2, urine leaching method: first scrape the sickness, and then draw the urine of the patient to the lesion wound, around the sickness about 5 cm. Apply again 1 week later. The effect of fresh urine is generally less than that of urine. The cure rate of urine is 90-99%. 3, salt water impregnation method: use salt 1 kg, water 40 kg, dubbed 1:40 light salt water, and boil open Liang Liang. Scrape the disease, use a brush or a brush to apply salt water to the disease, so as to impregnate the bark, and play the role of sterilization. After about 2 weeks, apply again. The cure rate of this method is above 80%. 4. Alkaline water impregnation method: Alkaline solution was mixed with the ratio of 1:5 for the alkaline surface and water. Scrape the sickness, apply alkaline water to the sickle with a small brush, and around the sickness about 5 cm, so that the alkaline solution can be fully impregnated into the bark. Then, it is tightly packed with a plastic film. After 10 days, it will be carried out once. After six months, the plastic film will be released. The cure rate of this method is above 85%. 5, garlic liquid sterilization method: the garlic boiled garlic, according to a ratio of 1:1 by adding 10% saline, made of garlic.
