How to prevent and control brown spot and shot hole disease in cherry blossoms
[Distribution] Cherry blossom brown spot and shot hole disease is an important disease of cherry blossom leaves and occurs in cherry blossom growing areas throughout China. [Symptoms] It mainly affects mature leaves and also affects young twigs. Infected leaves first show pinhead-sized purplish-brown dots, which soon enlarge into circular to nearly circular spots, 1-4 mm, brown in the center, slightly with concentric rings, with purple or reddish-brown edges, and grayish-brown fuzzy dots appear on the lesions; later, an abscission layer forms around the lesions, brown mold-like growth appears on both sides of the diseased leaves, and the center of the lesion dries up and falls off, forming round small holes and producing shot hole 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:

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.

The edges of the brown spots are purplish-brown, and grayish-brown mold spots appear on the lesions in the later stage. An abscission layer forms at the edge of the spot, and the lesion dries up and falls off, forming shot holes. II. Disease Pattern: The pathogen of cherry blossom brown spot shot hole disease overwinters in diseased leaves or shoot parts

What are the control methods for rice brown spot?
Symptoms Also known as rice sesame leaf blight. It occurs in all rice-growing regions nationwide. Disease can occur from the seedling stage to the harvest stage, and all aboveground parts of the rice plant can be affected, with leaves being the most common. When seeds are affected at the germination stage, the coleoptile turns brown, the sprout fails to emerge, and the cotyledon dies. Leaf and leaf sheath disease at the seedling stage mostly appears as elliptical lesions, the size of sesame seeds, dark brown; sometimes the lesions enlarge and merge into strips, and when there are many lesions the seedlings die. On leaves of adult plants, infection begins as small brown spots, gradually enlarging into elliptical spots the size of sesame seeds, with the center of the lesion brown to grayish white, the margin brown, and around it yellow halos of varying
