Fruit rot, also known as rotten skin disease, stinky skin disease, etc., occurs throughout the world. Rot disease mainly damages the branches of the resulting tree. Saplings and seedlings can also be harmed, but the incidence is less. In the early stage of the disease, it is difficult to identify from the appearance. If the epidermis is lifted off, dark brown spots with moist red and brown spots or brownish dry spots can be seen. Sometimes, the internal lesion area is larger and it is still not well recognized from the outside. . When the damage is heavy, the cortex rots and necroses and it is depressed with your finger. The diseased skin is easily peeled, the rotten cortex is red-brown, and the wet rot has distiller's grains. At the later stage of disease, the diseased department was dehydrated and contracted, darkened and submerged, and dark brown spots were produced on it. The pathogenic conidia became the source of infection. In addition to invading branches, it sometimes infects fruit. Symptoms of the lesions on the fruit are dark red round or irregular shaped, with rosy patterns and sharp edges. The diseased parts of the rot softened, slightly distiller's smell, easy peeling of the diseased fruit epidermis. The product is liquid, neutral. Easy to use, non-toxic and harmless.

The rot bacterium is a weak parasitic fungus. The pathogenic characteristic of this bacterium is that when the water content of the tree is low, the pathogenicity is strong, while other pathogenic bacteria mostly means that the greater the water content of the object, the more the air humidity is. The stronger the disease.
After the bacteria invade the plant, they secrete toxic substances and kill the cells. Then the mycelium continues to expand in depth, causing cortical tissue to rot. The disease can be plucked into apple, pear, peach, cherry, plum, willow, poplar and other deciduous fruit trees and broadleaf species. After germs invade the tree, they usually do not cause the disease immediately, but are latent. Whether or not the disease will occur later depends mainly on the host's disease resistance. What is the host disease resistance, that is, the degree of cell activation of the host, what is the degree of cell activation, that is, the cell wall, cytoplasm, organelles, cell membranes formed well, and the necessary continuous nutrients and water supply. If the plant lacks calcium, it will affect the construction of the cell wall. If the cell wall is loose, it will lead to weakening of the frame potential energy between the cell itself and the cells. Insufficient water will affect nutrient transport and absorption and transformation of nutrients such as cytoplasm and organelles. If the overall cell viability is strong, there will be no pathogenesis. According to investigations, the status of apple branches is almost 100%. The rate of colonization increased with the age of the tree. Normally growing shoots are generally not affected. When the tree or local tissue is weakened, the rot bacteria will turn from a sublimation state to a disease state. From the production point of view, during the early spring from the tree's water flow to the leaf during the fall from the tree began to fall asleep, the emergence of a strong period of disease. As the tree enters a vigorous growth period, the disease resistance gradually increases and the disease turns into a low tide.
Usually, after the fruit trees enter the result period, rot disease begins to occur. With the increase of tree age and continuous increase of yield, rot disease will increase year by year. Under normal management conditions, tree load is a key factor in the pathogenesis. Year after year results consume a lot of nutrients. If nutrient supply is insufficient, it will inevitably lead to rot disease. According to actual investigation, the lesions spread slowly when the water content of the shoots is 80-100%, and the lesions expand rapidly when the water content of the shoots is 67%. When pruning in winter, the pruning is too heavy, the wound is too much, and disinfection and protection are not timely, which is conducive to the occurrence of diseases. Freezing damage and hail can damage the tree and aggravate the rot disease.
At present, the agents for the control of rot include Fumeijing, Corbicillin, Decaying Enemy, Sclerotium, Arsenic Humic Acid, Copper Humate, Pingfuling, QuePaiHuo, Simeisu, Peracetic Acid, Strong Acid, Strong alkali and so on.
We believe that it is extremely easy to kill rot bacteria, and it is critical to improve the ability of cells to activate, and it is also the key to cure the disease. In the past, more emphasis was placed on sterilization. Most of the main ingredients of the pharmaceuticals were Fumei Shen. Although nutrients such as humic acid were added, the increase in nutrients through wounds did not improve cell activation. Although hydrogen peroxide and other strong oxidants can kill bacteria on the surface, the obvious effect is obvious, foaming, its lack of no systemic absorption, the holding period is too short, about 2 hours, due to strong oxidants on cells and organelles The damage is heavier and the result is not ideal. Strong acid and alkali are also not ideal. Because of the damage to the host at the same time as killing the bacteria.
Our research on the prevention of rot disease began in 1992 and progressed in 2004. Initially we found an ideal formula that was abandoned because of the high cost. Later, substances that can sterilize and activate plant cells were found on several plants, and rot disease can be cured with one dose. Generally do not relapse in 1-2 years.
