Sydney is a very nutritious fruit, especially in the heat and detoxification, and it has a high medicinal value. However, pear trees are a kind of tree species that are easy to be affected. Below the pro-farm network, we will introduce some common pests and diseases of pear trees and their prevention and treatment methods to solve some troubles.
1, pear
This is one of the most common parasites in pear trees. It mainly likes to parasitize the nutrients of pear trees on the leaves, which will seriously affect the rate of pear trees. The symptom is that the pear tree leaves are attached to the pear larvae, and the leaves begin to shrink into a cylindrical shape over time, eventually causing shedding. It is generally found that such leaves should be removed and burned in time to avoid more infections. In the initial stage, manual removal can be carried out to solve the serious problem. It can be sprayed with 50% parathion EC 3000 times.
2, pear sore disease
The so-called pear black spot disease, which has multiple results at the beginning, leads to abnormal growth of the fruit, and the disease is mostly caused by excessive humidity. The onset of the disease begins with the appearance of spotted marks on the surface of the pear, and then slowly mildews and blacks, which eventually leads to the wilting of the whole fruit. In addition, the disease of the pears is a disease of the group and should be treated promptly after the discovery. Fruit disease, tebuconazole, and black star speed powder are the commonly used agents for the treatment of this disease. It can also be sprayed with 40% new star emulsion 800-1000 times for early prevention.
3, pear rust
This disease is particularly harmful to the leaves, and the damage to the young pears is also high, mostly concentrated in the temperature alternating period of higher humidity. The surface of the leaves appears as rust-like spots, which then slowly dry up; the top of the fruit appears to be dry and necrotic. Such as cypress will seriously increase the incidence of morbidity, this should be noted. In the prone season, spray 20% rusting emulsifiable concentrate 1500-2000 times solution for prevention, twice a month for two months. If the disease occurs, it is treated with 20% powder rusting 600 times solution.
4, pear small heartworm
This is one of the most feared parasites in the pear tree fruit. Once it was discovered, Sydney was not saved and it rotted. Therefore, the prevention and treatment after the onset must be timely and important. Most of the parasites enter the fruit at the beginning, and the fruit grows with the growth of the insects. For the diseased fruit, the fruit is directly removed and taken out of the orchard for destruction. The surrounding trees should be sprayed immediately, and the two kinds of treatments are the common treatment methods.
