Summary: Mold, the tree has withered and is affected by moisture, the trunk will become moldy, and slowly grow white mold.
Mold is a type of fungus that is characterized by a well-developed mycelium and no larger fruiting body. Like other fungi, they also have cell walls, parasitism or saprophytic modes of survival. Mold can turn food into toxic substances, and some may produce toxins in food, known as mycotoxins.
Since the discovery of aflatoxins, there has been a growing concern about food contamination by molds and mycotoxins. One of the main conditions for mold growth and reproduction is that it must maintain a certain amount of moisture.
Causes of mold:
1. The walls of the production workshop are damp, and mold is easy to grow in the damp parts.
2. The pipelines and walls of condensate in the workshop are easy to grow mold, and the rupture of the water pipe will also lead to the production of mold.
3. Normal ventilation cannot be guaranteed in the workshop, and mold is easy to grow in the workshop under the specified humidity.

Mulberry scale
In fact, it is a kind of scale insect of the genus Pseudowhite Wheel Shield of the family Shield Scale, also known as Mulberry white scale, peach scale scale, etc., which mainly sucks the sap in the branches of plants by nymphs and female adults.
At the earliest, it mainly harmed mulberry, peach, apricot, walnut and other fruit trees in the orchard; In recent years, it has also begun to spread harm in the garden, mainly harming the national acacia, white ash, yueji, privet, pu tree, etc.
Because the mulberry shield scale is mainly used by female adults and nymphs to gather on the branches for stinging and sucking, so a dense layer of scale insects will be distributed on the branches of the trees that are harmed by it, and when these scale insects secrete a waxy layer, it will seriously affect the landscape effect of garden plants.
In addition, although the trees damaged by the mulberry scale will not die within 1 to 2 years, the sap in the branches will become less and less, and the growth will gradually weaken, and then the phenomenon of yellow leaves and dry branches will gradually appear. If it is not prevented in time, it will cause the whole tree to dry up and die after 2 to 3 years of continuous damage.
