Introduction:

The root-knot nematode disease of climbing rose has a wide range of hosts. In addition to damaging roses, it can also damage various flowers such as gladiolus, gerbera, and cyclamen.

Abstract: In this article, we analyze the symptoms of root-knot nematodes disease and the characteristics, then introduce three measures for controling the nematode who invades climbing rose roots.

1. Symptoms of root-knot nematode disease:
2. The incidence and epidemic characteristics of root-knot nematode disease in rose:
3. Three control measures to climbing rose root-knot nematode:

Symptoms of root-knot nematode disease:

Affected plants and fibrous roots form many solitary nodules, which are light and smooth at first, and then turn brown and rough. When the tumor tissue is cut open, white luminous dots can be seen, which is the female adult. The above ground part of the plant grows poorly, and the yield and quality of cut flowers decrease.

The incidence and epidemic characteristics of root-knot nematode disease in rose:

Multiple generations can occur in one year. Overwinter in the soil as larvae or root-knotted galls along with diseased debris. In the following year, when the environment is suitable, the larvae can directly invade the young roots, stimulating the moth tissue in the roots to form giant cells, which enlarge and form root nodules. After mating, the male and female worms lay eggs, which hatch into larvae that can be re-infected. Nematodes are spread through water streams and seedlings.

Three control measures to climbing rose root-knot nematode:

A. Soil disinfection

Soil disinfection is carried out before cultivation, which can be treated with heat or chemicals. Medicament can choose 80% dibromochloropropane emulsion or cramphos emulsion.

B. Implement crop rotation.

C. Seedling treatment.

Soak the seedlings in hot water at about 50°C for 20-30 minutes.
