Slime flux, also known as bacterial slime or bacterial wetwood, is a bacterial disease of certain trees, primarily elm, cottonwood, poplar, boxelder, ash, aspen, fruitless mulberry and oak. A wound to the bark, caused by pruning, insects, poor branch angles or natural cracks and splits, causes sap to ooze from the wound. Bacteria may infect ...
The mulberry fruit is a multiple, about 2–3 centimetres (3 ⁄ 4 – 1 + 1 ⁄ 4 inches) long. [2] [6] Immature fruits are white, green, or pale yellow. [6] The fruit turns from pink to red while ripening, then dark purple or black, and has a sweet flavor when fully ripe. [2] [6]
The red mulberry cannot be used for silk production as the white mulberry. Silkworms reject the leaves of the red mulberry. [36] The red mulberry cannot be used as a short-term solution, due to the time until the first fruit bearing. Instead, it requires long-term planning. The highest yields are obtained after 30–85 years. [37]
The leaves are much like the flowers when analyzing diversity. The leaves can be singly attached to the stem or alternating, they may be lobed or unlobed, and can be evergreen or deciduous depending on the species in question. [citation needed] The red mulberry can host numerous leaf types on the same tree. Leaves can be both lobed and unlobed ...
The leaves of the Morus plant are the only source of food and nutrition for silkworms, as their growth, larval development and its production of cocoons are dependent on the plant. Mulberry rust affects buds, leaves and branches, resulting in a decrease of quality of the leaves and their quantity. [11] It is most common in China. [9]
Symptoms can overlap across causal agents, however differing signs and symptoms of certain pathogens can lead to the diagnosis of the type of leaf spot disease. Prolonged wet and humid conditions promote leaf spot disease and most pathogens are spread by wind, splashing rain or irrigation that carry the disease to other leaves. [2]
Morus alba, known as white mulberry, common mulberry and silkworm mulberry, [2] is a fast-growing, small to medium-sized mulberry tree which grows to 10–20 m (33–66 ft) tall. It is native to China and India and is widely cultivated and naturalized elsewhere.
References to diseases now known to be caused by phytoplasmas can be found as far back as 1603 (mulberry dwarf disease in Japan). [4]Such diseases were originally thought to be caused by viruses, which, like phytoplasmas, require insect vectors and cannot be cultured.
