Symptoms are also known as mulberry blight. It is easy to occur on young mulberry branches with too heavy leaf collection, and the half branches are more common. In the early spring, the water-stained elliptical lesions on the surface of the shoots were gradually expanded. When the lesions surrounded the winter buds, the winter buds could not germinate. When the lesions were circumscribed for 1 week, the branches above the diseased part died. Sangge
The cause of stem blight is different, and it is divided into many kinds, such as Sangping rash, mulberry skin disease, mulberry rough rash disease, sangjie rash disease, mulch dryness disease, mulberry branch blight, mulberry rash and so on. Sangbing blight mainly affects half-branches or young shoots and seedlings, resulting in large oval lesions, some as long as 30cm, yellowish-brown to auburn, edematous when wet, shrinking depression after drying, disease and health Obviously, the bark of the diseased tree is easy to peel off, the skin is black after the dehiscence, and there is a black dense rash under the skin. There are a lot of small black spots on the stems of infected mulberry skin disease. The protrusions are rough and obvious, like sharkskin skin. Mulberry blight mostly damages mulberry seedlings or saplings. It produces dark brown lesions at the base of the shoot near the ground, and the cortical necrosis and shedding are obvious, with many dark-black rashes around.
There are three pathogens that cause pathogenic sangyang rash and stem blight: Massaria phorcioides Miyake called the black body of the sarcophagus and belongs to Ascomycete spp. The asccus shell is spherical to oblate spheroid, with mycelial soft tissue winding on the surface, papillary in the orifice, opening outside the epidermis, and endogenous ascaria and lateral filaments. Ascido-bar-shaped, 8-celled ascospores are arranged in 2 rows. Ascospores are initially colorless, and later become dark brown with 4-6 membranes. M.moricola Miyake called the Sangsheng black crust as an ascomycete subphylum. The asccus shell is spherical or nearly round, the shell wall is black, there are a few ascospores, the ascospores have short stalks, and the ascospores have three septa surrounded by a glial membrane. M.mori Miyake synonym M.mori (P. Henn) Ito called the mulberry black crust, belonging to the phylum Ascomycotina. The ascospora shell is similar to the mulberry black cluster. Ascaria cylindrical, with short handle, size 140-16040-50 (um), containing 8 ascospores. Ascospores spindle to oblong, with 3 membranes, size 51-6518-26 (um).
Transmission routes and pathogenic conditions The pathogenic bacteria live as ascosbic spores or conidia in the diseased branches. Invasion through the wound. The vulnerability of the tree vigor is morbid. The leaves are rough or pests are severe and attacked by storms, hail and frost damage are prone to disease. Mulberry management is not good, and improper fertilization is very serious.

UTZ Freeze Dried Coffee: also known as Freeze-dried Coffee, it is an Instant Coffee made by freezing liquid products and removing ice through sublimation.
The freeze-dried coffee chips retain the original flavor of coffee well. Due to its loose and porous internal structure and fast dissolution rate, it is a "instant coffee" that is convenient to measure and can easily control the concentration of the beverage.
