What are the common pests and diseases of pomegranate trees? Here is the latest summary

The pomegranate tree is a fruit tree prone to many pests and diseases, and every year farmers suffer some yield loss because of these diseases, and in severe cases the entire crop can be lost. Below, let us take a look at some common diseases of pomegranate trees, so that when the disease occurs you can judge the type of disease yourself and carry out post-disaster prevention and treatment.

1. Pomegranate stem clearwing moth

This is a pest that is extremely destructive during its larval stage. The female lays eggs on the branches of the pomegranate tree, and the larvae feed on the sap of the branches, seriously affecting the growth of the pomegranate tree. The peak incidence period is generally around July. In the early stage of the disease, the main sign is an extremely high death rate of new branches, and in severe cases old branches also die. In the later stage, the larvae bore into the main trunk, causing the whole plant to wither. So if farmers find that the death rate of that year's branches is very high, they should be alert to the pomegranate stem clearwing moth. It is recommended to promptly clean up old and dead branches, and after the disease occurs the plants can be sprayed with trichlorfon insecticide.

2. Pomegranate dry rot

This is a disease caused by a fungus, and the onset period spans the flowering stage and the fruiting stage. The disease mostly occurs during the rainy season and the subsequent period of higher humidity. In the early stage, brown spots appear on the corolla of flowers or fruits, and they slowly rot and spread, eventually covering the entire fruit or flower. The prominent symptom in the flowering stage is severe flower drop, and most of the flowers show obvious blackening. The prominent symptom in the fruiting stage is a large number of fruits showing black rot, along with fruit drop. Carbendazim suspension concentrate can be used to try to treat it.

3. Black spot disease

If you commonly see quite a few black spots on the leaves of the pomegranate tree, and within a period after the black spots appear the leaves wither and drop very quickly, this is basically caused by black spot disease. In severe cases it causes a large number of leaves to drop, the pomegranate tree can no longer carry out photosynthesis, and it finally slowly withers. If you notice this, it is best to treat it promptly, and carbendazim is a good choice.

4. Scab

Scab is a disease that mostly occurs on the pomegranate fruit. It mainly shows as spots resembling scabs on the surface of the pomegranate, which then slowly spread, the affected area further dries out, and finally the entire fruit turns into a dried lump. The onset period is concentrated in the early fruiting stage, and the symptoms are obvious. Once noticed, it is generally recommended to remove the fruit directly to reduce the pathogen, and finally treat with carbendazim powder.

The above are the common pests and diseases of pomegranate trees, and these pests and diseases pose a relatively great threat to pomegranate trees. In general, disease prevention follows the principle of reducing pathogens to lower the chance of onset, so farmers should clean up the residual branches of the fruit trees after harvest and take them out of the orchard.
