- The direct cause: by the fungi Fusarium, Pythium, Phytophthora, and nematodes.
- Indirect causes: often due to the care of gardeners such as not handling garden soil, fungi and nematodes in the soil are not destroyed; Excessive watering causes waterlogging, suffocating roots and reducing oxygen in the soil, creating conditions for pathogens to develop; abuse of chemical fertilizers for a long time; poorly permeable soil; the drain hole is clogged; Use disease-prone, non-tolerant varieties.

Effective remedy for yellow leaf rot disease
For citrus orchards, the soil is required to be high, with good drainage. If the garden is low, the banks must be raised. At the same time, there must be a good drainage system.
- Choose disease-free seedlings.
- Balance the amount of water, and reasonable fertilizer. Prioritize the use of microbial organic fertilizers. In order to increase the humus, the soil is porous and destroys harmful pathogens in the soil.
- Regularly prune leaves, old, disease-prone branches
- Apply lime at the beginning of the rainy season to disinfect
- Regularly monitor and check plant diseases.
- Treat nematodes, soil mealybugs, and root-damaging spiders around the root zone such as Comda 250EC, and Sago Super 20EC, periodically 2-3 times/year. Especially in the dry season.
