Problems solved by technology
At present, the prevention and control of this disease is still based on chemical control. In production practice, it has been found that the following problems exist in the use of common chemical agents to prevent and control hawthorn anthracnose: first, the control effect is poor, and an ideal pesticide has not been found yet; second, anthracnose The occurrence of hawthorn almost runs through the entire growth period, and even occurs during the storage period. Therefore, long-term use of pesticides for prevention and control will cause pollution and seriously affect the quality of hawthorn.

Embodiment
[0019] Embodiment: the control method of this hawthorn anthracnose comprises:
[0020] 1. During the growth period of hawthorn, weeds are implemented in the whole garden, and the grass depth is kept at 10-20 cm. The grass in the whole garden is artificially planted in the hawthorn garden in early October;
[0021] 2. Use sunshade nets on hawthorn trees from July to August;
[0022] 3. Spray Chinese herbal medicine extract after hawthorn fruit setting and fruit expansion stage, that is, take 250 parts of Coptis chinensis and 200 parts of white fresh skin, add 3000ml of water, decoct for 20 minutes, filter, add 80 parts of mature vinegar to make a medicinal liquid, and add 100 parts of water After dilution, spray once after fruit setting and fruit expansion period.

The invention discloses a hawthorn anthracnose control method. The hawthorn anthracnose control method is a comprehensive control method mainly aiming at Chinese herbal medicine extracting solution control and includes the steps that a whole orchard is swarded during the growing period of hawthorns, and a sunshade net is used on hawthorn trees during the June and the August; after fruit setting of the hawthorns, Chinese herbal medicine extracting solutions made of coptis chinensis and cortex dictamni are sprayed during the fruit expansion period. It is testified through field tests that the control effect reaches 99.3%, and the hawthorn anthracnose control method is safe, efficient, free of pollution or residues and low in control cost.
Description
technical field [0001] The invention relates to a method for preventing and controlling fruit tree diseases, in particular to a method for preventing and controlling hawthorn anthracnose. Background technique [0002] Hawthorn anthracnose is a latent infection fungal disease that occurs widely and seriously. It is distributed and harmful in hawthorn production areas in my country. It is an important disease that endangers the healthy development of hawthorn industry. The disease mainly infects young leaves, branches, spikes and fruits, causing fallen flowers, fallen leaves, dead shoots, withered pedicles, fallen fruits and rotten fruits, resulting in tree vigor decline, reduced production or even loss of harvest, resulting in significant economic losses. Pathogenic bacteria continue to harm fruits during the storage and transportation period of fruits, which is also an important storage disease. How to effectively control the occurrence and harm of anthracnose has become an...
