Rose and pomegranate pest control

1. Diseases and Pests

1. Japanese wax scale

One of the common pests. When they are nymphs, they will attach themselves to leaves or new branches to suck sap and secrete mucus that is poisonous to plants. It can cause sooty mold disease, causing leaves and fruits to fall off, and in severe cases, it can lead to death. Generally speaking, drugs can be used for prevention and treatment. You can also use other hostile animals to suppress them.

2. Pomegranate stem moth

One of the common pests, it can be found in most pomegranate-producing areas in my country. It harms the new shoots or branches of trees, affects the growth of trees, and greatly harms the fruits, reducing their yield and quality, and can cause plant death. If you find sick branches, you need to remove them immediately to prevent the larvae from continuing to grow and endanger the whole plant.

3. Heartworm

The larvae of this pest will harm the fruit, causing needle-sized spots on the fruit. As the insects grow, the fruit will be further eaten away, seriously affecting the health of the fruit. In mid-May, you can use parathion to spray the tree trunks, which can effectively inhibit the growth and reproduction of the pests and diseases. If you encounter diseased fruits, you should pick them off in time and dispose of them by deep burial.

2. Diseases

1. Black spot

The disease causes lesions on the plant's branches, fruits and flowers. This disease can seriously affect the shape of the plant, causing the branches and trunks to become cracked, rough, and hard, and even exposing the wood. For trees, after the disease is found, the lesions need to be removed with a knife in time, and the wounds need to be disinfected with bacteria. For flowers and fruits, you can use carbendazim for spraying to effectively prevent the occurrence of diseases.

2. Brown spot disease

This disease can seriously damage the leaves and fruits of trees, causing them to fall. When the infection first occurs, brown spots will appear. If found, they need to be removed promptly to prevent further spread of the disease. Before germination, spraying with Bordeaux solution can prevent and control the disease.
