As one of the "seven sages" of bonsai, sparrow plum is an important material for making bonsai, which is deeply loved by bonsai lovers. However, if infected with diseases and insect pests, it will greatly reduce its value. So which diseases and insect pests are Finch plum easy to catch? How to prevent and control these diseases and insect pests? Here, the pro-agricultural network introduces several common diseases and insect pests of Finch plum and the corresponding control methods.

1. Rust of sparrow plum

The rust of Finch plum is caused by fungus. Caused by multicellular rust, it will produce spores that make the leaves yellow, or the disease spots on the front of the leaves begin to be orange, the tissue of the disease spots slowly become thicker and thicker, and the back of the leaves bulge, affecting beauty. With the passage of time, the disease spot will expand, can expand to round, black, and finally cause the leaves to die and fall off.

Prevention and control methods:

The rust spot of sparrow plum can be treated by pruning: completely cut off the fungal branches and buds from the sparrow tree before the spring rain. In addition, you can also spray parathion or pentachlorophenol sodium 350 times liquid plus 1.01 kg before spring rain to reduce diseases.

Second, longicorn beetle pests

When a longicorn beetle pest occurs in sparrow plum, the female longicorn beetle will bite through the bark and lay eggs on the top of the branch. The newly hatched larvae will eat under the bark, grow up and gradually eat into the trunk and root, and then gradually empty the stem and die.

Prevention and control methods:

The larvae can be stabbed to death by inserting moderate wire into the wormhole directly.

3. Red spider pest

Red spider disease is a reddish-brown oval appearance. Red spiders will form a web above the plant leaves to lay eggs and use mouthparts to pierce the branches and leaves to absorb the sap of the branches and leaves, resulting in the destruction of the chlorophyll of the leaves and the gradual yellowing of the leaves. Grayish-yellow spots will also appear on the leaves until the leaves dry and fall off.

Prevention and control methods:

Can directly spray dichlorvos or dimethoate 1000 times liquid to 1500 times liquid.

The above are the three common diseases and insect pests of Finch plum and the measures to control these three kinds of diseases and insect pests, hoping to provide some help for bonsai lovers. The cortex of the branches of Finch plum itself is relatively thin, and the ways of nutrient transport are also different, so we must pay attention to maintenance measures during culture.
