Anthurium pests and control methods

Nematodes

Symptoms

The nematodes are mainly root-knot nematodes, which mainly harm the growth of plants. Gallbladder-like masses can be seen at the base of the plant. Of course there is another type of nematode, the boring nematode, which causes brown spots on the roots of the plant without any obvious swelling.

When plants are infested with nematodes, they are easily damaged by fungi and develop root rot.

Prevention and treatment measures

The main way to solve the problem of nematodes is prevention. Disinfect the soil before planting, and you can choose sterilizers such as Bisumid. Or irrigate the roots of the plants with pesticides.

When the pest is serious, it is recommended to change the pot and replant, expose the soil to the sun for a period of time, remove impurities in the soil, and replant.

Scale insects

Symptoms

Scale insects are often found on the leaves of anthuriums and are pests with round brown shells. In serious cases, the leaves are covered with pests, which not only affect the growth of the plant but also reduce its ornamental value.

Prevention and treatment measures

Strengthen maintenance, ventilate frequently, ensure suitable humidity in the maintenance environment, control water appropriately, and remove pests in time when found. They can be rinsed with clean water or scraped with bamboo strips.

When the pest is serious, spray fungicides to kill them. The concentration of the drug should be low and the spraying should be even. However, try to avoid spraying pesticides during home maintenance as it may affect human health.

Red Spider

Symptoms

Red spider mites attach to anthuriums, causing the leaves and flowers to fade, affecting the varieties of the leaves and flowers.

Prevention and treatment measures

When red spider mites appear, spray pesticides for prevention and control. Commonly used pesticides include cypermethrin, flumethrin, and dicofol.
