Apple Mould Heart Disease is a kind of disease that harms the fruit during the period from fruit ripening to storage, causing the fruit to rot, heart rot or early fall off. The pathogenic bacteria overwinter between mycelium in diseased fruit, necrotic tissue, or scales hidden in the bud by spores. In spring, when the temperature and humidity are appropriate, various types of spores are produced. By the wind and rain, the pathogenic spores enter the ventricle from the calyx tube and the stamens. The pathogens mainly invade the flowering period, latent behind the fruit, and multiply with the development of the fruit. Generally, the disease can be dissected in the tree as early as the end of June, but it is mostly in the later stage of fruit growth. Some diseases show symptoms until the storage period, causing mildew. The occurrence of the disease is closely related to climate and species. Warm and humid flowering, is conducive to the reproduction and dissemination of germs. The orchard is low-lying and canopy closure, and poor ventilation is conducive to disease. There was a significant difference in the incidence of disease among apple varieties. All the fruits were susceptible to infection when they were gargled, and the length of pods was linked to the core of the fruit. The gingiva was small and the pods were shorter. Marshals such as Red Star, Golden Delicious and Fuji are more susceptible to disease. The prevention and treatment of apple fungal heart disease should be combined with the method of controlling the growth phase of the drug and the control of storage conditions during the storage period. During the growing period of the apple growth period, three key medication periods should be seized: 1 Inflorescence buds expand to the red period. Combining the control of apple powdery mildew and others, it is possible to select bactericidal agents with good permeability and therapeutic properties, such as: 30% difenoconazole cyproconazole suspension 1000-1500 times or 430 grams per liter tebuconazole suspension 2000 ~ 3000 times of liquid, 1.5% of thimethone water emulsion 500 times, to eradicate the spores of pathogenic bacteria produced on branches and stems. 2 early flowering period. Choose a fungicide that has no effect on fruit set, to eliminate germs on the flower. Such as 3% multi-antimycin agent 400 times, or 4% agricultural anti-120 agent 600 to 800 times, 80% mancozeb WP 700 times. 3 young fruit period. This is a critical period for the prevention and treatment of mycotic heart disease. The systemic fungicide should be selected 10 days after the apple is dropped, combined with the control of apple ringworm, anthrax, and 430 g/l tebuconazole suspension 4000-5000 times, or 10% difenoconazole water dispersible granules 3000 to 4000 times, 70% phospine aluminum manganese zinc wettable powder 1000 times. After harvesting, prevention and treatment of those fruits with poor hardness and lack of luster on the fruit surface should be removed and stored. If conditions permit, they can be pre-stored in a short-term storage at 10°C to 15°C, and after removing the disease, they can be stored in an air-conditioned cold store.
