Common diseases and pests in Cameo and their control methods

Common diseases of Cameo: Rust

Cameo leaves themselves are not a shape that everyone likes to see. After being infected with rust, large rust-brown spots appear on the epidermis of the stems and extend upward from the base of the stems. In severe cases, the stems are covered with spots. There are rust-like patches on the leaves.
Prevention and control measures: Cut off the diseased leaves, allow new buds to sprout again, and then spray with 2000-3000 times diluted 12.5% ​​diniconazole wettable powder.

Common pests in Cameo: root-knot nematodes

Root-knot nematodes will burrow into the stems of Cameo and chew through the plant, causing the heart to rot and causing 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 severe, you can try cuttings and then burning the stems of the mother plants that have root-knot nematodes.
