How to control root rot nematode disease by breeding rich trees? The root rot nematode disease of the rich tree is a small nematode that exists in the soil, which mainly harms the roots and other underground organs of the host plant, occasionally infects the aboveground parts such as stems and fruits, and the tissue of the infected parts turns dark brown and flooded. There are scars on the surface, the roots are short and rotten, and the aboveground parts show growth, dwarfing, withering or death. In terms of control, proper application of nitrogen fertilizer, especially urea, can inhibit the occurrence of short-body nematodes. The healthy insect-free breeding materials were selected, and according to the sensitivity of different breeding materials to temperature, the suitable combination of temperature and time was selected to treat the breeding materials with hot water. The soil was treated with fumigant nematicide such as must-be, and non-fumigant nematicidal agents such as clenophos, Clementan, Milol and methamidophos could be used to control the soil before planting.
