Apple and P. edulis, commonly known as water rot and mildew, are common infectious diseases during storage and can cause large losses of apples and pears.
First, the symptoms
The fruit was damaged. The surface of the lesion was yellowish-white, concave, and round. The fruit rotted and was extremely moist and deep into a conical shape. When the conditions are right, it will develop rapidly and the whole fruit will rot for more than 10 days after onset.
Second, the incidence of the law
The pathogens are invaded by wounds caused by mechanical operations and insects. Although the lenticels can invade, they are secondary. When sick and healthy fruit are mixed together, they can be contacted and spread. When the air is wet, small mold-like mold pieces are produced, which are initially white and then turn blue-green, covered with powdered material, which is the conidia of pathogens. Penicillium fungus is resistant to hypothermia. When the storage temperature is close to 0°C, the diseased part can still expand slowly. When the temperature is high at the early and late stages of storage, the disease spread rapidly.
Third, control methods
The prevention and control of Penicillium must be started before the fruit is harvested, combined with comprehensive prevention and treatment measures such as transportation and storage period management, in order to receive good results.
1. Pre-harvest control. Spray 200 times lime (1:2:200) Bordeaux mixture or 25% carbendazim wettable powder 1000 times before spraying on the fruit to evenly spray on the fruit. It can also cure anthrax, black Star disease and powdery mildew.
2. Avoid mechanical damage. This is one of the important measures to prevent the disease. Prevent stab wounds, crushing, and bruising during harvesting, grading, packaging, and handling.
3. Storage place sterilization. Sterilize the storage area before storage. Acetaldehyde can be used to treat acetaldehyde in the air at 0.5% concentration for 180 minutes, or 1% concentration for 120 minutes, or 2% concentration for 60 minutes to prevent penicillosis.
4. Medicament dip fruit. Use 25% carbendazim WP 1000 times, dip fruit after harvesting, ie immerse, no more than 1 minute, soak after storage. If 500 times 2,4-D butyl ester is added to the medicament, not only can the effect of fruit dipping be improved, but it can also be kept fresh.
