What are the control methods for nematode disease in clivia (Clivia miniata)?

Nematodes are a type of microscopic animal.

Disease pattern: Parasitic nematodes of clivia are generally tiny, with a body length of less than 1 mm, an unsegmented body, and a semi-transparent elastic cuticle covering the outside; the internal organs are embedded in the body cavity, bounded directly by the body wall. They are dioecious, with males and females differing in form. Eggs are laid inside egg sacs, and the egg sacs are oval. They reproduce through mating of male and female nematodes to lay eggs. After ornamental flowers are damaged, they grow poorly, the plants are stunted, the leaves become wrinkled, and they may even die early. Swellings and warts of different sizes can be seen on the roots, the root system is underdeveloped, and growth is hindered. Dissecting the small warts reveals white round granular objects inside, namely the white nematode bodies.

Control methods:

To control diseases caused by nematodes, drugs such as 1,2-dibromo-3-chloropropane, carbofuran, and dazomet are effective.
