Common pests of Huayuejin and their control methods

Common pests of Huayuejin: scale insects

The damage is widespread, sucking the juice from stems and leaves, causing poor growth of the plant, and in severe cases, withering and death.

Its peak period is earlier than that of red spider mites, and it often reproduces in large numbers in early spring. However, its damage is also easy to control. That is, it is often concentrated in only a few plants. Sometimes one plant is full of scale insects, while the neighboring plant has none.
Prevention and control methods: When the number is small, use a brush to remove it. In addition, you can also use 800-1000 times diluted Supusha for spraying. Mixing a certain amount of furadan into the culture soil has a preventive effect, but the efficacy is only three months.

Common pests of flower moon brocade: red spider

Red spider mites are one of the most common plant pests, and they reproduce quickly, producing about 10 generations a year. Red spiders are extremely small in size. They use their piercing-sucking mouthparts to insert into the mesophyll and stem bark of plants, sucking the sap of the plants, causing the plants to turn yellow or even wither.

Prevention and control methods: Spray 1500 times diluted 40% oxydemeton-methyl emulsifiable concentrate.

Common pests of flower moon brocade: white spider

White spiders are not originally pests in our country; they are imported. Generally, imported products have strong resistance to pesticides, so it is difficult to prevent and control white spiders. However, it is difficult and you still have to be on guard, otherwise, a beautiful pot of Huayuejin will be ruined!

Prevention and control methods: Spray with 2000 times diluted 5% cypermethrin suspension.

Common pests of Huayuejin: root-knot nematodes

Root-knot nematodes will drill into the stems of the jasmine and bite the plant, causing the heart to rot and the leaves to fall off.

Prevention and control methods: Fill pots with carbendazim. When the damage caused by insect pests is not very serious, you can use carbendazim to irrigate the pots to kill the root-knot nematodes.

If the infestation is already serious, you can try cutting the top of the plant and then burning the mother plant with root-knot nematodes.
