What are the treatment methods for cherry tree wounds?
During the growth of cherry trees, long-term exposure to the sun makes the bark prone to aging and damage, causing rot and forming hollows, which affects the growth and lifespan of the cherry tree. Therefore, once a wound is found on a cherry tree, treatment measures must be taken immediately. Generally, first use a sharp knife to shave and scrape the wound clean, then disinfect it with a disinfectant such as a 5-degree lime sulfur mixture or ink, and finally apply a protective agent such as tung oil to prevent the wound from rotting and promote its healing. If the cherry tree wound has already become a hollow, it should be repaired. The method is: first dig out the rotten wood inside the hollow, then scrape clean the dead tissue at the edge of the hollow, then disinfect with a chemical agent, and use leaf mold and charcoal powder to wrap the rotten area to promote the restoration of its normal physiological functions. Observe carefully and keep the leaf mold and charcoal powder wrapping moist. If it dries out, water it to maintain a certain humidity. After such treatment, the hollow of the cherry tree will slowly grow adventitious roots. Combined with annual soil improvement, the adventitious roots will continue to grow, and finally extend into the soil and gradually thicken. The adventitious roots will transform into a trunk, becoming a healthier main trunk that sprouts and produces flowers.

What are the symptoms of cherry brown spot shot hole disease?
Symptoms of cherry brown spot shot hole disease: This disease occurs on leaves, new shoots and fruit. But it mainly damages leaves, producing circular or nearly circular spots on both sides of the leaves, about 1 to 4 mm in diameter, with clear edges and slight concentric rings; the outer ring is sometimes purple or reddish brown, and the center is grayish white or brown with faint concentric rings. In the later stage, grayish brown mold-like material, namely the conidiomata, occasionally appears on both sides of the spots, more abundantly on the underside of the leaves. The spots often dry up and fall off, forming shot holes, and the holes at the edges of these spots are neat. Leaves with many shot holes drop early, and the spots on new shoots are purplish brown, with grayish brown mold-like material also produced on the spots.

Occurrence Patterns and Control Methods of Cherry Brown Spot Shot Hole Disease
Symptoms: Small brown, grayish-brown, or purplish-brown spots initially appear on the leaves, gradually forming circular lesions that are non-water-soaked and opaque, with no yellow-green halo around the lesions, 2-4 in diameter, with clear boundaries and a purplish-brown outer margin. In the later stage, the center turns white or brown, slightly zonate, and the lesions die and fall off, forming irregular shot holes. 2. Occurrence patterns: The pathogen overwinters on fallen leaves and spreads by wind and rain in the following spring. The disease begins in June, with the peak period from August to September. Heavy rainfall promotes disease occurrence and epidemic, and weakened tree vigor leads to severe disease. 3. Control methods:

Cherry Blossom Pest Control Methods and Technical Key Points
1. Cherry blossom pests and diseases include the white peach scale (Pseudaulacaspis pentagona), various nettle moths, and the apple fruit moth (Phalera flavescens), among others. The white peach scale is mainly distributed in cherry blossom cultivation areas, occurs commonly, and is quite severe in individual fields. The damage has already caused the leaves to basically fall off, with pest populations at extremely high densities, appearing snow-white from both near and far. It is speculated that the first-instar nymph stage of the white peach scale should be around late August to early September. The first-instar nymph stage is the best time to carry out spray control. All growers should carry out coordinated prevention and control to keep the pest population base below the allowable economic level. Control method: spray during the nymph stage with Sujieke at 1000-1500
